MICROANATOMY

Detailed explanation-1: -If the arteries supplying the heart become narrow, blood flow can slow down or stop. This can cause chest pain (stable angina), shortness of breath, and other symptoms. Narrowed or blocked arteries may also cause problems in the intestines, kidneys, legs, and brain.

Detailed explanation-2: -Arteries narrowed and damaged by high blood pressure have trouble supplying blood to the heart. Too little blood flow to the heart can lead to chest pain (angina), irregular heart rhythms (arrhythmias) or a heart attack.

Detailed explanation-3: -Atherosclerosis is where your arteries become narrowed, making it difficult for blood to flow through them. It increases your risk of heart attack and stroke. Lifestyle changes, like stopping smoking, eating healthily and exercising regularly, can help stop atherosclerosis getting worse.

Detailed explanation-4: -Blood pressure rises when the arteries are blocked and the blood can no longer flow freely. This is particularly pronounced during strenuous situations, as the heart must work even harder to supply the body with enough oxygen and nutrients.

Detailed explanation-5: -A narrowed or blocked blood vessel deprives tissues of blood. Gangrene is the death and decay of tissue. There is no cure. The only treatment is surgical amputation of the affected body part.
