Please give me the answer to the A-level Biology Question How do I answer questions on the adaptations of the lungs

A-level Biology Help >>>>> How can I answer questions regarding the adaptations made by the lungs? Begin by describing the role for the lung: Gas exchange. Then, look at the modifications using the number of marks available as a guideline for the number of changes 1 mark for each mark. Fick's Law of Diffusion states: it is the ratio of )Surface Volume x Area difference)and the distance of diffusion. Therefore it is necessary to have a large surface area and concentration gradient that has an extremely small distance between them is required . A large volume ratio of surface area boosts diffusion across the membranes of the alveoli and into the capillaries. The capillaries have a constant concentration difference is created due to the constant flow of blood through the capillaries. This results in the flow of new blood through CO2 and the ventilating of the lungs that releases oxygen in high concentration. gradient. As the rate of diffusion rises. The alveoli of the lungs or air sacs, are enclosed by a vast capillary network which has walls that are both capillaries and the alveoli exactly the same ( 1 layer of cells each) This reduces the diffusion distance and consequently increases the rate. Surfactant lines the inside of the alveoli. This can increase the rate of diffusion.The inner core heart temperature at ~37.5 degrees celsius is greater than that of the room temperature, and thus increases the rate of diffusion.
