ANATOMY

Detailed explanation-1: -There are three types of blood vessels: Arteries carry blood away from your heart. Veins carry blood back toward your heart. Capillaries, the smallest blood vessels, connect arteries and veins.

Detailed explanation-2: -By adulthood, we each have 60, 000 miles of blood vessels inside our bodies – that’s more than twice the distance around the world. Those vessels keep blood flowing, supplying your tissues with oxygen and nutrients, and keeping your organs, including the heart, healthy.

Detailed explanation-3: -Types of blood cells. There are 3 types of blood cells – red blood cells, white blood cells and platelets. Red blood cells (erythrocytes) carry oxygen to all cells in the body. The oxygen is carried to cells on a protein in red blood cells (called hemoglobin).

Detailed explanation-4: -Solution: The three kinds of blood vessels found in human beings are arteries, veins and arterioles. Arteries are the blood vessels that carry blood from the heart to the various parts of the body. Veins are the blood vessels that carry blood from the body parts to the heart.

Detailed explanation-5: -There are five classes of blood vessels: arteries and arterioles (the arterial system), veins and venules (the venous system), and capillaries (the smallest bloods vessels, linking arterioles and venules through networks within organs and tissues) (Fig 1).
