Cat anatomy blood vascular system


The aorta is the largest artery in the body and is divided into 3 parts: the ascending aorta, arch of the aorta, and descending aorta. The aorta is the largest artery in the systemic circulatory system. Blood is pumped from the left ventricle into the aorta and from there branches to all parts of the body. The aorta is an elastic artery, meaning it is able to distend. When the left ventricle contracts to force blood into the aorta, the aorta expands.

This stretching generates the potential energy that helps maintain blood pressure during diastole, since during this time the aorta contracts passively. Diagram of Human Heart : This diagram of the human heart shows all the major vessels, and arrows indicate the direction of flow through the heart.

The aorta is divided into three parts: the ascending aorta, where the aorta initially leaves the heart and points superiorly toward the head; the arch of the aorta where the aorta changes direction; and the descending aorta where the aorta points inferiorly toward the feet. Ascending Aorta : The aorta has three parts: the ascending, the arch and the descending.

The ascending aorta has two small branches, the left and right coronary arteries. These arteries provide blood to the heart muscle, and their blockage is the cause myocardial infarctions or heart attacks. The arch of the aorta has three branches: the brachiocephalic artery, which itself divides into right common carotid artery and the right subclavian artery, the left common carotid artery, and the left subclavian artery. These arteries provide blood to both arms and the head.

The descending aorta is the largest artery in the body; it runs from the heart down the length of the chest and abdomen. It is divided into two portions, the thoracic and abdominal, in correspondence with the two great cavities of the trunk in which it sits. Within the abdomen, the descending aorta branches into the two common iliac asterisk revealer online that provide blood to the pelvis and, eventually, the legs.

The ascending aorta is the first portion of the aorta; it includes the aortic sinuses, the bulb of the aorta, and the sinotubular junction. Its total length is about five centimeters. The aortic root is the portion of the ascending aorta beginning at the aortic annulus, the fibrous attachment between the heart and the aorta, and extending to the sinotubular junction. Just above the aortic valve are three small dilations called the aortic sinuses. The two anterior sinuses give rise to the coronary arteries, while the third posterior sinus does not usually give rise to any vessels and so is known as the non-coronary sinus.

The sinotubular junction is the point in the ascending aorta where the aortic sinuses end and the aorta becomes a tubular structure. At the junction of the ascending aorta with the aortic arch, the caliber of the vessel increases with a bulging of its right when a pisces hates you. It is enclosed in a tube of the serous pericardium, which also encloses the pulmonary artery.

The ascending aorta is covered at its beginning by the trunk of the pulmonary artery and, higher up, is separated from the sternum by the pericardium, the right pleura, the anterior margin of the right lung, some loose areolar tissue, and the remains of the thymus.

Posteriorly, it rests upon the left atrium and right pulmonary artery. The arch of the aorta follows the ascending aorta and begins at the level of the second sternocostal articulation uebert angel belt the right side. Aortic arch : This diagram shows the arch of the aorta and its branches.

The arch of the aorta, or the transverse aortic arch, is continuous with the upper border of the ascending aorta and begins at the level of the upper border of the second sternocostal articulation of the right side.If you're seeing this message, it means we're having trouble loading external resources on our website.

Function: Arteries carry blood away from the heart, and veins carry blood back to the heart. Circulating blood supplies cells throughout the body with oxygen and removes waste carbon dioxide.

Because of these living cells suspended in the plasma, blood is considered a fluid connective tissue not a fluid. Function: It transports oxygen and other essential substances throughout the body, fights sickness, and performs other vital functions. Cell fragments called platelets, or thrombocytes, make up about 2 percent of blood. Function: Platelets clump and form a plug in the damaged area of a torn blood vessel to stop blood loss. White blood cells, also called leukocytes, are the disease-fighting components of blood.

Arteries transport blood away from the heart. In the systemic circulation arteries and their branches transport oxygenated blood and veins carry deoxygenated blood. Pathologies: Aortic aneurysm, arteriovenous malformations, diabetes type 1, diabetes type 2. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.

The capillaries also connect the branches of arteries and to the branches of veins. Systemic circulation moves blood between the heart and the rest of the body. It sends oxygenated blood out to cells and returns deoxygenated blood to the heart. Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.

The heart is a hollow, muscular organ that pumps oxygenated blood throughout the body and deoxygenated blood to the lungs. The heart comprises four chambers enclosed by a heart wall. Pathologies: Angina, arrhythmia, atrial fibrillation, cardiomyopathy, congenital heart defects, coronary artery disease, diabetes type 1, diabetes type 2, diabetic heart disease, heart attack, heart failure, heart valve diseases, mitral valve prolapse, muscular dystrophy, pericardial disorders, rheumatoid arthritis.

The muscular wall of the heart has three layers. The outermost layer is the epicardium or visceral pericardium. The epicardium covers the heart, wraps around the roots of the great blood vessels, and adheres the heart wall to a protective sac.

The middle layer is the myocardium. The innermost layer, the endocardiumlines the interior structures of the heart. This large vessel is formed by the junction of the two brachiocephalic veins on either side of the root of the neck. This vessel ascends along the front of the vertebral column on the right side of the aorta. It perforates the diaphragm and passes behind the serous pericardium, opening into the right atrium at its base. Function: The inferior vena cava returns blood to the heart from the abdominal walls and viscera below the diaphragm.

The right atrium, one of the two upper chambers of the heart, receives deoxygenated blood from the vena cava superior, inferior and the coronary sinus, and empties into the right ventricle.

CT Angiography (CTA)

The tricuspid valve, one of the two atrioventricular valves in the heart, controls blood flow from the right atrium into the right ventricle. Function: The tricuspid valve plays a vital role in the cardiac cycle, preventing backflow and ensuring one-way blood flow through the heart.Appropriate ischemia models are required for successful studies of therapeutic angiogenesis. While collateral routes are known to be present within the innate vasculature, there are no reports describing the detailed vascular anatomy of the murine hindlimb.

In addition, differences in the descriptions of anatomical names and locations in the literature impede understanding of the circulation and the design of hindlimb ischemia models. To understand better the collateral circulation in the whole hindlimb, clarification of all the feeding arteries of the hindlimb is required. The aim of this study is to reveal the detailed arterial anatomy and collateral routes in murine hindlimb to enable the appropriate design of therapeutic angiogenesis studies and to facilitate understanding of the circulation in ischemia models.

Arterial anatomy in the murine hindlimb was investigated by contrast-enhanced X-ray imaging and surgical dissection. The observed anatomy is shown in photographic images and in a schema. Previously unnoticed but relatively large arteries were observed in deep, cranial and lateral parts of the thigh. The data indicates that there are three collateral routes through the medial thigh, quadriceps femoris, and the biceps femoris muscles.

Furthermore, anatomical variations were found at the origins of the three feeding arteries. The detailed arterial anatomy of murine hindlimb and collateral routes deduced from the anatomy are described. Limitations on designs of ischemia models in view of anatomical variations are proposed. These observations will contribute to the development of animal studies of therapeutic angiogenesis using murine hindlimb ischemia models.

The word cerebrovascular is made up of two parts — "cerebro" which refers to the large part of the brain, and "vascular" which means arteries and veins. Together, the word cerebrovascular refers to blood flow in the brain. The term cerebrovascular disease includes all disorders in which an area of the brain is temporarily or permanently affected by ischemia or bleeding and one or more of the cerebral blood vessels are involved in the pathological process.

Cerebrovascular disease includes stroke, carotid stenosis, vertebral stenosis and intracranial stenosis, aneurysms, and vascular malformations. Restrictions in blood flow may occur from vessel narrowing stenosisclot formation thrombosisblockage embolism or blood vessel rupture hemorrhage. Lack of sufficient blood flow ischemia affects brain tissue and may cause a stroke.

The heart pumps blood up to the brain through two sets of arteries, the carotid arteries and the vertebral arteries. The carotid arteries are located in the front of the neck and are what you feel when you take your pulse just under your jaw. The carotid arteries split into the external and internal arteries near the top of the neck with the external carotid arteries supplying blood to the face and the internal carotid arteries going into the skull.

Inside the skull, the internal carotid arteries branch into two large arteries — the anterior cerebral and middle cerebral arteries and several smaller arteries — the ophthalmic, posterior communicating and anterior choroidal arteries.

These arteries supply blood to the front two-thirds of the brain.

Human Anatomy & Physiology Laboratory Manual: Making Connections, Cat Version, 2nd edition

The vertebral arteries extend along side the spinal column and cannot be felt from the outside. The vertebral arteries join to form a single basilar artery near the brain stem, which is located near the base of the skull. The vertebrobasilar system sends many small branches into the brain stem and branches off to form the posterior cerebellar and posterior meningeal arteries, which supply the back third of the brain.

The jugular and other veins carry blood out of the brain. Because the brain relies on only two sets of major arteries for its blood supply, it is very important that these arteries are healthy. Often, the underlying cause of an ischemic stroke is carotid arteries blocked with a fatty buildup, called plaque. During a hemorrhagic stroke, an artery in or on the surface of the brain has ruptured or leaks, causing bleeding and damage in or around the brain.

Whatever the underlying condition and cause are, it is crucial that proper blood flow and oxygen be restored to the brain as soon as possible. Without oxygen and important nutrients, the affected brain cells are either damaged or die within a few minutes. Once brain cells die, they cannot regenerate, and devastating damage may occur, sometimes resulting in physical, cognitive and mental disabilities.

The majority of cerebrovascular problems can be identified through diagnostic imaging tests. These tests allow neurosurgeons to view the arteries and vessels in and around the brain and the brain tissue itself. Cerebral angiography also called vertebral angiogram, carotid angiogram : Arteries are not normally seen in an X-ray, so contrast dye is utilized.

The patient is given a local anesthetic, the artery is punctured, usually in the leg, and a needle is inserted into the artery. A catheter a long, narrow, flexible tube is inserted through the needle and into the artery.

It is then threaded through the main vessels of the abdomen and chest until it is properly placed in the arteries of the neck.

This procedure is monitored by a fluoroscope kadva patel special X-ray that projects the images on a TV monitor. The contrast dye is then injected into the neck area through the catheter and X-ray pictures are taken.

Carotid duplex also called carotid ultrasound : In this procedure, ultrasound is used to help detect plaque, blood clots fasm tutorial other problems with blood flow in the carotid arteries.If your institution subscribes to this resource, and you don't have a MyAccess Profile, please contact your library's reference desk for information on how to gain access to this resource from off-campus.

Blood moves through the vascular system secondary to pressure and osmotic gradients similar to a plumbing system, but, unlike our household pipes, the system of blood vessels is not made up of static and inflexible structures. The vascular system is dynamic and always changing to regulate blood flow to the body and its essential organs.

The system of blood vessels with the heart at its center is critical for delivering oxygenated blood and essential nutrients to organs and tissues and removing and transporting waste products. This chapter will cover the normal circulatory system and its structures and congenital and acquired diseases including atherosclerosis, trauma, and inflammatory and infectious processes.

The pulmonary vascular system and its diseases will also be discussed. The cardiovascular system develops very early in gestation as early as 15—16 days due to the limited energy sources available from the egg and yolk sac. The cardiovascular system delivers nutrients to the increasingly actively dividing cells and disposes of waste products through its connections with the maternal vasculature of the placenta.

The heart and blood vessels are created from the mesoderm that forms blood islands isolated cell masses around which the endothelial tubes are formed. Vascular smooth muscle cells and connective tissue derived from the local mesoderm then surround the endothelial tubes. The heart begins to beat and blood begins to circulate throughout the blood vessel network around the 4th week of gestation Figure Embryological development of blood vessels.

In the extraembryonic yolk sac, mesodermal precursor cells aggregate to form blood islands, the sites of development of endothelial and primitive blood cells. Within the blood islands, centrally-located cells become primitive blood cells, whereas outer cells give rise to endothelial cells ECs. ECs then form the vascular primary plexus which is subsequently remodeled to form the yolk sac vasculature.

In the embryo proper, mesodermal precursor cells differentiate into the vascular primary plexus and major vessels, aorta, and cardinal vein. After arterial and venous ECs are specified, the complex blood vasculature is formed via extensive remodeling. At embryonic day E 9. Transcriptional regulation of endothelial cell and vascular development.

Circ Res. The arterial system carries oxygenated blood away from the heart to the organs and periphery providing oxygen and nutrients to the cells at a distance. The capillary system is responsible for the exchange of new supplies and the waste products.

The venous system carries the deoxygenated blood with its waste products back The cardiovascular system includes the heart and blood vessels. The cardiovascular system performs the function of pumping and carrying blood to the rest of.

The cardiovascular system includes the heart and the blood vessels (the veins and the arteries). The function of the heart is to pump blood.
