<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.
- The most typical cause of coronary artery disease is atherosclerosis, which is a buildup of fatty plaques in your arteries.
