Blood is a connective tissue made of components like plasma, blood cells, and platelets. It creates connectivity between different organs of the human body with arteries, veins, and capillaries. Blood circulation occurs through these blood vessels connected to the heart. Based on the blood composition, the blood has several significant roles. The primary function of blood is to transfer oxygen to the lungs and bring the waste material to the kidney. Blood also maintains the warmth of the human body, prevents infection, and gives immunity.

The blood vessels are channeled to supply blood in different parts of the body, and based on their functions, they are of three different types, arteries, capillaries, and veins. The arteries mainly carry blood from the heart and three distinct layers, namely tunica externa, tunica media, and tunica intima. Veins function to supply blood to the heart; like arteries, they also have three layers, tunica externa, tunica media, and tunica intima.
