Function Explain how the structure of the blood vessels relates to their respective functions Outline the role and location of valves in the circulation of blood
The primary function of blood is to deliver oxygen and nutrients to, and remove wastes from, the body cells; but that is only the beginning of the story. The specific functions of blood also include defense, and maintenance of homeostasis, such as distributing heat where it is needed.
By the end of this section, you will be able to: Compare and contrast the three tunics that make up the walls of most blood vessels. Distinguish between elastic arteries, muscular arteries, and arterioles on the basis of structure, location, and function.
Blood vessels transport blood around the body. There are three different types of blood vessels in the body: arteries, capillaries and veins. Their main function of arteries is to carry blood away from the heart. The right ventricle pumps blood into arteries that go to the lungs.
30 paź 2023 · The blood transports the oxygen from the alveoli to the remotest cells of the body. Because of the higher gas pressure in the plasma (relative to the cells), it diffuses to the tissues. Carbon dioxide diffuses from the cells into the blood due to the higher gas pressure in the tissue.
In the diagram of the human heart, which structures are most closely associated with the transport of deoxygenated blood? A. A, B, and C B. B, F , and I C. C, D, and E D. D, H, and I 9. The diagram represents several major circulatory pathways in the human body. Which sequence represents the normal blood flow in circulation to the lungs?
Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting.
