ANATOMY

Detailed explanation-1: -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-2: -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-3: -When the coronary arteries narrow, the heart may not get enough blood when it needs it most-like when exercising. This can cause chest pain (angina) or shortness of breath. Heart attack. A heart attack can happen if a cholesterol plaque breaks open and causes a blood clot to form.

Detailed explanation-4: -Similarly, as blood volume decreases, pressure and flow decrease. As blood volume increases, pressure and flow increase.

Detailed explanation-5: -Clogged or blocked arteries, or atherosclerosis, can lead to hypertension (high blood pressure), stroke, or even death, so it is vital to understand the signs and symptoms of blocked arteries.
