What type of blood vessels carry blood away from the heart?

Blood vessels that carry blood away from the heart are classified as arteries. This is because arteries are responsible for transporting oxygenated blood from the heart to the tissues and organs throughout the body, with the exception of the pulmonary arteries, which carry deoxygenated blood from the heart to the lungs. Arteries have a thick muscular wall that allows them to withstand and regulate the high pressure at which blood is pumped from the heart.

Understanding the structure and function of arteries is crucial in anatomy and physiology. They branch into smaller vessels, known as arterioles, which further regulate blood flow to specific areas of the body. While veins and capillaries also play essential roles in the circulatory system, their functions differ as veins carry blood back to the heart, and capillaries are involved in nutrient and gas exchange at the tissue level.
