WebAn efficient blood supply to transport molecules to and from the exchange surface increases effective exchange. Examples of this include: the network of blood capillaries … WebMammalian lungs maximise surface area through the presence of large amounts of alveoli, this means there are more sites for gas exchange to occur, thereby increasing the rate of diffusion. Diffusion is the net passive movement of particles from a region of high concentration to a region of low concentration, thus a steep concentration gradient must …
Web31 de dez. de 2024 · Gas exchange is efficient due to a thin respiratory membrane, the high speed of diffusion, high surface area and lipid solubility of carbon dioxide and oxygen.

Adaptations of the alveoli: Moist walls – gases dissolve in the moisture helping them to pass across the gas …
WebThe fluid is drawn into the muscle tissue during exercise. This increases the surface area of air in contact with the cells. Gases diffuse in through the spiracles and down the tracheae and tracheoles. Ventilation movements of the body during exercise may help this diffusion. The spiracles can be closed by valves and may be surrounded by tiny ...
