Aortic aneurysm a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning , coarctation of the aorta narrowing of the aorta, the largest artery in the body , Takayasu arteritis a rare inflammatory disease affecting the aorta and its branches. Thoracic vascular disease. Thoracic aortic aneurysm a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning in the thoracic, or chest, portion of the aorta.
Abdominal vascular disease. Abdominal aortic aneurysm a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning in the abdominal portion of the aorta. Peripheral venous disease. Deep vein thrombosis also called DVT; a blood clot in a deep vein located within the muscles of the leg , varicose veins. Lymphatic vascular diseases. Lymphedema swelling caused by interruption of the normal drainage pattern in the lymph nodes.
Vascular diseases of the lungs. Granulomatosis with polyangiitis an uncommon disease in which the blood vessels are inflamed; mainly affects the respiratory tract and the kidneys , angiitis inflammation of blood vessels , hypertensive pulmonary vascular disease high blood pressure in the lungs' blood circulation due to vascular conditions.
Renal kidney vascular diseases. Renal artery stenosis blockage of a renal artery , fibromuscular dysplasia a condition that weakens the walls of medium-sized arteries and occurs predominantly in young women of childbearing age. Because vascular conditions and diseases may involve more than one of the body's systems at a time, many types of doctors treat vascular problems. Health Home Conditions and Diseases.
The vessels of the blood circulatory system are: Arteries. Blood vessels that carry oxygenated blood away from the heart to the body. Blood vessels that carry blood from the body back into the heart. Examples include: Respiratory system. What is vascular disease? What causes vascular disease? Causes of vascular disease include: Atherosclerosis. Certain conditions of the vascular system are inherited.
What are the effects of vascular disease? Examples of the effects of vascular disease include: Coronary artery disease. Heart attack, angina chest pain Cerebrovascular disease. Stroke, transient ischemic attack a sudden or temporary loss of blood flow to an area of the brain, usually lasting less than 5 minutes but not longer than 24 hours, with complete recovery Peripheral arterial disease.
Heat is made by the body's tissues. This happens as they break down nutrients for energy, make new tissue, and give up waste matter. A vascular disease is a condition that affects the arteries and veins. Most often, a vascular disease affects blood flow. It may do this by blocking or weakening blood vessels. Or it may do this by causing damage to the valves that are in veins. Organs and other body areas may be harmed by vascular disease due to partly or fully blocked blood flow.
This is a buildup of plaque. Plaque is a deposit of fatty substances, cholesterol, cell waste, calcium, and fibrin. It can build up in the inner lining of an artery. It's the most common cause of vascular disease. It's not known how atherosclerosis starts or what causes it. It's a slow, ongoing disease that gets worse over time. It may start as early as childhood. But the disease can also get worse quickly. It causes the buildup of fatty deposits along the innermost layer of the arteries.
This thickening narrows the arteries. It can lessen or fully block the flow of blood to organs and other body tissues. Blood clots. A blood vessel may be blocked by an embolus. This is a tiny mass of debris that moves through the bloodstream. Or it may be blocked by a thrombus. This is a blood clot. In general, inflammation of blood vessels is referred to as vasculitis.
This includes a range of disorders. Inflammation may lead to narrowing and blockage of blood vessels. Injury of the blood vessels may lead to inflammation or infection. This can damage the blood vessels and lead to narrowing and blockage.
The functions of the blood vessels include supplying all organs and tissues of the body with oxygen and nutrients. They include removing waste products, fluid balance, and other functions. Because of all these functions, conditions that affect the vascular system may affect the part s of the body supplied by a certain vascular network. Coronary artery disease.
This can cause heart attack or angina chest pain. Cerebrovascular disease. This can cause stroke or transient ischemic attack TIA. TIA is a short-term loss of blood flow to an area of the brain. It usually last less than 5 minutes but not longer than 24 hours, with complete recovery.
Peripheral arterial disease. This may cause claudication. The connective tissue in this layer is quite dense where it is adjacent to the tunic media, but it changes to loose connective tissue near the periphery of the vessel. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart arteries and the vessels that return blood to the heart veins.
The primary function of capillaries is the exchange of materials between the blood and tissue cells. Capillary distribution varies with the metabolic activity of body tissues. Tissues such as skeletal muscle , liver , and kidney have extensive capillary networks because they are metabolically active and require an abundant supply of oxygen and nutrients.
Other tissues, such as connective tissue, have a less abundant supply of capillaries. The epidermis of the skin and the lens and cornea of the eye completely lack a capillary network.
About 5 percent of the total blood volume is in the systemic capillaries at any given time. Another 10 percent is in the lungs. Smooth muscle cells in the arterioles where they branch to form capillaries regulate blood flow from the arterioles into the capillaries.
Veins carry blood toward the heart. After blood passes through the capillaries, it enters the smallest veins, called venules. From the venules, it flows into progressively larger and larger veins until it reaches the heart.
