WebGas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. WebQuestion. The alveoli and blood capillaries make up the gas exchange surface of the lungs, and as the arrows in the diagram (Figure 3) illustrate, this is where oxygen and carbon dioxide move in a particular direction. a) With reference to simple diffusion, explain why oxygen and carbon dioxide move in the directions illustrated by the arrows.
WebJan 24, 2024 · The gaseous exchange takes place between alveoli present in the lungs and the blood capillaries which are present around them. This is a process in which passive diffusion occurs. Oxygen is moved from the alveoli into the blood, and carbon dioxide is moved from the blood capillaries into the alveoli which is exhaled out of the body. WebBecause of the enormous number of alveoli (approximately 300 million in each human lung), the surface area of the lung is very large (75 m 2). Having such a large surface area increases the amount of gas that can diffuse into and out of the lungs. Basic Principles of Gas Exchange.
