write three types of blood vessels?
Answers
Answer:
Vein, Artery, Capillary
Explanation:
Vein
Vein is a blood vessel that carries blood toward the heart. The blood circulates in the body through a system of tubes called blood vessels. The three kinds of vessels are arteries, capillaries, and veins. Most veins return blood to the heart after the blood has delivered nourishment to the tissues and taken up waste products. Blood in veins is called venous blood.
Artery
Artery is the name of the tubes or blood vessels through which blood is pumped away from the heart to the various parts of the body. The blood carried by most arteries is bright red because it has picked up oxygen while passing through the lungs. However, the blood that flows through the arteries connecting the right side of the heart with the lungs has not yet picked up oxygen. This blood has a brownish color. If an artery is cut, blood gushes out in spurts timed with the heartbeats. Veins differ from arteries because they carry the blood back to the heart instead of away from the heart. If a vein is cut, blood flows from it in an even stream.
Capillary
Capillary is the smallest blood vessel in the body. It can be seen only under the microscope. Most capillaries are so small that only one blood cell can pass through them at a time. Capillaries connect the smallest arteries with the smallest veins. They make up a network of blood vessels throughout the body. The largest capillaries are in the bone marrow and skin. The smallest are in the brain and lining of the intestine.
(Not copied from the Internet)
There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. They're tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
