Why do you think the heart needs more arteries than a leg muscle?
Answers
Answer:
heart pumps blood throughout the body , it needs more arteries to transport more and more oxygenated blood efficiently throughout the body than the leg muscles
Explanation:
Arteries are the vital channels that carry oxygen-rich blood from the heart to all the body's tissues. When blockages develop, blood flow slows and tissues suffer. Blockages in the coronary arteries cause angina and heart attacks; blockages in the arteries that supply blood to the brain cause strokes. But the peripheral arteries that carry blood to the legs and other parts of the body are also vulnerable. Heart attacks and strokes get all the publicity, but peripheral artery disease (PAD) is a major problem that deserves more attention and respect — especially since new methods make diagnosis easier and treatment better than ever before...
Like most strokes and nearly all heart attacks, PAD (formerly called peripheral vascular disease) is a form of atherosclerosis. Peripheral artery disease begins when LDL ("bad") cholesterol passes from the blood into the wall of an artery. Arteries damaged by high blood pressure, smoking, or diabetes are at particular risk. As the cholesterol builds up, it triggers inflammation, which adds to the damage. Unless treatment halts the process, the cholesterol deposit builds up into a plaque, or blockage, that narrows the artery. Mild narrowing may not produce any symptoms, but moderate narrowing may prevent tissues from getting the blood they need to fuel the extra work of exercise. When blockages are severe, the tissues suffer even during rest. Blood clots can add insult to injury by increasing blockages.

The most frequently affected locations include the aorta (about 30%), the femoral and popliteal arteries (80%), and the tibial artery (40% — because men can have blockages in several arteries, the numbers add up to over 100.
The popliteal pulse is one of the pulses you can detect in your body, specifically in the portion of your leg behind your knee. The pulse here is from blood flow to the popliteal artery, a vital blood supply to the lower leg. Several medical conditions can affect blood flow to and from the popliteal pulse
