How does atherosclerosis develop, and what are its possible long-term consequences?

Atherosclerosis means hardening of arteries

Explanation:

When fat or calcium accumulate in the arteries they form plaque that plaque hardens and narrows the arteries. And this plaque blocks the blood flow.

Atherosclerosis leads to many serious problems like heart stroke, even death also occurs.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
