WebOne of the primary functions of the alveoli is to create a large surface area in the lungs. Why is a large surface are so important? Tutorial The primary function of the lung is gas exchange. The alveoli allow this gas exchange to occur. Each alveoli has a network of capillaries that carry oxygen-poor red blood cells. WebNo large animals can depend on diffusion alone for gas exchange as they have a very small surface area to volume ratio. Much larger organisms needed a specialised gas exchanged …

WebGas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. WebThe surface area of the tracheoles exposed to air increases. Large insects contract muscles associated with the abdomen to force air in and out of the spiracles. This is known as 'abdominal pumping'. Abdominal pumping increases the efficiency of gas exchange between the tracheoles and muscle tissue of the insect. Explain why
