(2 marks)", "Image ImageDescription": "The alveoli provide the lungs with a large surface area for diffusion. Name two other structural features of the lungs that assist diffusion. (2 marks) a) Cardiac hypertrophy leads to greater stroke volume / cardiac output. Greater capillary networks. Increased blood volume and haemoglobin levels. b) Permeability of alveoli (partially permeable membrane) Short distance from alveoli to capillary. Slow movement of blood through capillaries. Moisture layer enhancing the uptake of oxygen.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
