What type of blood vessel carries blood away from the heart?

Veins
Capillaries
Arteries
Venules

The correct answer is: Arteries

Arteries are specifically designed to carry blood away from the heart. They are muscular and elastic, which allows them to withstand and regulate the high pressure of blood being pumped from the heart. The primary function of arteries is to transport oxygenated blood to various tissues and organs, except for the pulmonary arteries, which carry deoxygenated blood to the lungs for oxygenation. In contrast, veins carry blood back to the heart, capillaries are small vessels that facilitate the exchange of oxygen, carbon dioxide, and nutrients between blood and tissues, and venules are small veins that collect blood from capillaries and transport it to larger veins. Understanding the distinct functions and roles of these different types of blood vessels is essential in phlebotomy and overall circulatory system comprehension.
