What is the iliac artery?
This branch of the abdominal aorta divides into the internal and external iliac arteries. Internal iliac. Derived from the common iliac artery, this artery supplies blood to the bladder, pelvis, and external portion of the genitals. It also supplies the uterus and vagina in females. External iliac.
Why are the walls of arteries thicker than those of veins?
Because arteries are moving blood being pumped out by the heart, the walls of arteries are thicker and more elastic than those of veins. This is because the blood in the arteries is passing through with a higher pressure than in veins. The thick, elastic walls of arteries accommodate that pressure.
What is the largest artery in the body?
Arteries come in a variety of sizes. The largest artery of the body is the aorta, which begins at the heart. As they move further from the heart, arteries branch off and become increasingly smaller. The smallest arteries are called arterioles.
Which artery supplies blood to the thigh and divides into the various smaller arteries that supply the legs?
Femoral. Derived from the external iliac artery, this artery supplies blood to the thigh and divides into the various smaller arteries that supply the legs.
Which artery sends blood to the heart?
The ascending aorta distributes oxygen and nutrients to the heart via the coronary arteries. Aortic arch. This has three major branches — the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. It sends blood to the upper body, including the head, neck, and arms. Descending aorta.
Why is it important to keep arteries healthy?
Because of their vital function, it’s important to keep arteries healthy. Damaged or narrowed arteries can lead to the body not getting an adequate blood supply, which can put you at risk for things such as heart attack or stroke.

What is renal artery stenosis?
Renal artery stenosis is a narrowing of the diameter of the renal arteries. When the renal arteries narrow, the result is restricted blood flow to the kidneys, which may lead to impaired kidney function and high blood pressure (referred to as renovascular hypertension (RVHT). Renal artery stenosis can occur in one or both kidneys. The primary cause of renal artery stenosis is atherosclerosis. Symptoms of renal artery stenosis include high blood pressure that does not respond to treatment and severe high blood pressure in individuals younger than 30 or greater than 50 years of age. Renal artery stenosis is diagnosed with imaging and functional tests. Treatment for renal artery stenosis include medication or surgery.
What is the main artery in the neck?
Carotid artery surgery is a surgery to treat carotid artery disease. The carotid artery is the main artery present on both sides of the neck that supplies blood to the brain and face. A buildup of the fatty substance (plaques) can block the blood flow in the carotid arteries entirely or partially, resulting in a stroke.
What is the condition where the legs do not receive enough blood flow?
Peripheral artery disease is a condition in which extremities (usually the legs) do not receive sufficient blood flow due to the narrowing of or blocks in arteries. Peripheral artery disease is also likely to be a sign of more widespread accumulation of fat deposits in the arteries (atherosclerosis or plaque).
What is the term for a buildup of plaque on the walls of the arteries?
Peripheral artery disease (PAD), peripheral vascular disease (PVD), or peripheral vascular occlusive disease (PVOD) is a common condition where there is a buildup of fatty deposits (plaque) on the walls of the arteries causing them to narrow. PAD is an abnormal narrowing of the arteries that supply blood to the hands and feet.
