What type of vessels does blood circulate through?

Blood circulates through a network of arteries, veins, and capillaries, which together form the cardiovascular system. Arteries are responsible for carrying oxygen-rich blood away from the heart to various tissues in the body. As blood travels through the body, it reaches the smallest blood vessels known as capillaries. Capillaries are crucial for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.

After passing through the capillaries, blood that is now low in oxygen returns to the heart through veins. This circulation system ensures that blood is continuously transported throughout the body, delivering essential substances and removing waste products. Each type of vessel serves a unique and vital function in maintaining proper blood flow and bodily function, making all three types—arteries, veins, and capillaries—essential components of the circulatory system.
