Proper circulation provides nutrients and oxygen to all the organs and tissues, keeps them functioning properly, and helps with the removal of waste from tissues. “Poor blood circulation can ...
Coronary arteries are the blood vessels that supply to the heart for its normal function. Blood vessel disorders occur in coronary arteries would affect cardiac activity. For instance, due to atherosclerosis, the plaque would obstruct and causes ischaemia - the reduction of blood flow through the arteries. Ischaemia would then result in the ...
Ischemia causes not only insufficiency of oxygen, but also reduced availability of nutrients and inadequate removal of metabolic wastes. [7] Ischemia can be partial (poor perfusion) or total blockage. The inadequate delivery of oxygenated blood to the organs must be resolved either by treating the cause of the inadequate delivery or reducing ...
Buerger's disease – inflammation and swelling in small blood vessels, causing the vessels to narrow or become blocked by blood clots. [18] Raynaud syndrome – a peripheral vascular disorder that causes constriction of the peripheral blood vessels in the fingers and toes when a person is cold or experiencing stress. [19]

In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease, and heart attacks. [4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [5]
a reduction of blood flow to the heart that can be caused by stenosis, spasm, or acute occlusion (by an embolus) of the heart's arteries. resistance of the blood vessels. This can be caused by narrowing of the blood vessels; a decrease in radius. [34] Blood flow is proportional to the radius of the artery to the fourth power. [35]
