WebThe alveolus is the terminal component of the lung. The efficiency of gas exchange across its wall and into the blood is dependent on several factors including; adequate ventilation, adequate blood supply and the structure of the alveolus.Through breathing in and out, we remove carbon dioxide and maintain the partial pressure of oxygen. This ... WebGas exchange by diffusion depends on the large surface area provided by the hundreds of millions of alveoli in the lungs. It also depends on a steep concentration gradient for oxygen and carbon dioxide. This gradient is maintained by continuous blood flow and constant breathing. 13.4 Review Questions What is gas exchange?

Here are some features of the alveoli that allow this: they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries. Can alveoli affect lungs? When you exhale, the alveoli shrink, forcing carbon dioxide out of the body. smart card mitsaiWebAir then travels down the pharynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles, which house the first site of gas exchange. The respiratory bronchioles open into the alveolar ducts, alveolar sacs, and alveoli. hillary high sleeper cat post
