Arteries are muscular, tube-like blood vessels that transport oxygen-rich blood away from your heart to all of your body's tissues and cells. Acting as the high-pressure "superhighways" of your circulatory system, they deliver vital nutrients and hormones while removing waste.

Key CharacteristicsDirection: Arteries always carry blood away from the heart. (The only exception is the pulmonary artery, which carries deoxygenated blood to the lungs).Structure: They have thick, elastic, and muscular walls to withstand the high pressure of blood being pumped directly from the heart.Main TypesElastic Arteries: Located closest to the heart (e.g., the aorta), these are larger vessels with more elastic tissue designed to absorb the initial force of a heartbeat.Muscular Arteries: Medium-sized vessels (e.g., femoral, radial, and coronary arteries) that contain more smooth muscle to actively direct and control blood flow to specific organs and tissues.Arterioles: Tiny, smaller-diameter branches that deliver blood directly into microscopic capillaries.Common Arterial ConditionsAtherosclerosis: The buildup of fats, cholesterol, and plaque in the arterial walls, which stiffens and narrows them, restricting blood flow.Coronary Artery Disease: Plaque buildup in the specific arteries that supply blood to the heart muscle, potentially leading to a heart attack.Aneurysm: An abnormal bulge or ballooning in the wall of an artery.
