The coronary arteries, which leave the aorta (the main artery of the body) just after it leaves the heart. Most people have two coronary arteries (left and right), although some people have three.
coronary arteries
Only in the tiny blood vessels that feed the cells in those tissues.
Larger humans always have more blood than smaller humans. They need a larger volume to feed and oxygenate their many more cells.
I think you mean the coronary arteries - the heart muscle itself has many blood vessels that feed it. When a big one gets blocked, the result is a heart attack.
the two blood vessels that carry blood from the body to the heart are the inferior vena cava and the superior vena cava
Additional irregular heartbeats can occur as a result of this procedure, as can damage to the blood vessels that feed the heart.
Our cells are located in a sea of lymph, a pale fluid. The lymphatic vessels run parallel to the blood veins in the body. The vessels of the lymph system are filled with a fluid called lymph that is collected from the space between the cells in the body. The lymph fluids feed the cells of the body by transporting various nutrients such as salts, minerals, and proteins to every cell of the bodyRead more: What_do_lymph_vessels_do
Arteries feed into capillaries, the capillaries give oxygen and nutrients to every cell in the body and take toxins and CO2 from every cell in the body, from there the blood in the capillaries go into your veins (the blue blood vessels) which go to your heart.
The venules are small vessels that connect capillaries to veins.The corresponding vessels that feed into the capillaries are arterioles.
The sympathetic system causes the vessels to constrict (shut blood to core systems) and is often called the fight or flight response. The parasympathetic system causes the vessels to relax and is often called the feed and breed response.
The lungs function to oxygenate blood and rid it of gases. When we inhale, oxygen travels into our lungs, diffuses into our blood stream and is pumped throughout our body where it can feed our bodies cells. Gases and other wastes from our cells then diffuse back into our bloodstream and travel to the appropriate areas to be removed. The lungs being one of those areas then function to remove the gases (specifically carbon dioxide and excess oxygen) so they can be exhaled.
It is more likely that a heart problem will cause polycythemia than the other way around.But because polycythemia causes your blood to thicken and slows blood flow, it increases your risk of developing blood clots. If a blood clot occurs in your head, it can cause a stroke. If they reach the coronary arteries that feed the heart muscle, a heart attack will be the result.
