Blood vessels are a part of the circulatory system that transport blood throughout the body. They are tubular structures that include arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart to different parts of the body, while veins carry deoxygenated blood back to the heart. Capillaries are tiny, thin-walled vessels that connect arteries and veins, allowing for the exchange of nutrients, oxygen, and waste products between blood and surrounding tissues. Blood vessels also play a crucial role in regulating blood pressure and temperature.
