ARTERY

Arteries are vital blood vessels in the circulatory system responsible for transporting oxygen-rich blood away from the heart to various tissues and organs throughout the body. Characterized by their thick, elastic walls, arteries can expand and contract in response to pulsatile blood flow, allowing them to maintain blood pressure and regulate supply. The largest artery in the human body is the aorta, which branches into smaller arteries, ultimately delivering oxygen and nutrients to every cell. Arteries feature three distinct layers: the innermost endothelium, a middle layer of smooth muscle, and an outer layer of connective tissue. Maintaining arterial health is crucial, as conditions like atherosclerosis can lead to narrowing and hardening of the arteries, increasing the risk of cardiovascular diseases. Regular exercise, a balanced diet, and avoiding smoking are key lifestyle choices to promote arterial health.
