Web26 aug. 2024 · Adaptations of the alveoli: Thin walls – alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls – gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls – allow gases to pass through. Carbon dioxide diffuses in the opposite direction. WebAmmonia is present as gaseous NH 3 in the air around the alveolar interface in the lungs due to its volatile nature. Blood ammonia is tightly regulated via the urea cycle for healthy persons and the concentration of ammonia represents more requirements in medicine since it is a molecule produced during protein metabolism and involved in numerous health …
