"WebAlveoli are highly adapted for gas exchange by diffusion between air in the lungs, and blood in the capillaries. They are folded in order to maximise the surface area to volume ratio. This allows more gas exchange to take place. The alveoli wall linings are moist, allowing oxygen and carbon dioxide to dissolve easily. " - How are lungs adapted for gas exchange bbc

GCSE Science Revision Biology "Gas Exchange in the Lungs"

WebThe primary purpose of gas exchange is to get rid of carbon dioxide and take up oxygen. Gas exchange takes place between blood and alveoli in the lungs, and then between blood and tissue cells all around the body through simple diffusion. Gasses cross the membranes at the alveolar-capillary membrane in the lungs, where oxygen enters and carbon … WebDiffusion. Diffusion is when particles spread from an area of high concentration to an area of low concentration. The molecules would move randomly, and they would eventually become evenly distributed. The particles move down the “concentration gradient” and this process takes no energy (it’s a “passive” process”).
