<h3>What about cardiovascular system?</h3>

Heart and blood vessels, which make up your cardiovascular system, deliver oxygen and nutrition to your body's organs so they can function.
Blood vessels also transport waste such as carbon dioxide to be disposed.
Conditions affecting the heart or blood vessels are collectively referred to as cardiovascular disease.
It is frequently associated with atherosclerosis, an accumulation of fatty deposits in the arteries that increases the risk of blood clots.
The heart, blood arteries, and blood make up the cardiovascular system.
Its main job is to carry deoxygenated blood back to the lungs and to carry nutrients and oxygen-rich blood to all regions of the body.

Atherosclerosis can be brought on by unhealthy lifestyle choices such smoking, being overweight, not exercising, and eating poorly.
