How are the alveoli adapted for gas exchange
Web20 de fev. de 2024 · Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes during – Internal respiration – this is the movement in the internal tissues between cells and capillaries, and – External respiration – when gas is exchanged between the alveoli and lung capillaries. Which animals use diffusion? WebThe alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they give the lungs a really big surface …
