Life Under pressure
Description
This program follows the journey of a red blood cell around the circulatory system to demonstrate the efficient and elegant design of oxygen and food delivery to all parts of the body and the removal of wastes before they can do harm. It shows how the veins and arteries are structured to perform their tasks: muscular arteries to transmit the force of the heartbeat, veins with valves to insure the blood's return to the heart.
