There are a lot of alveoli present thus increasing surface area for gas … WebHow is the alveoli adapted for its job? The ruched, cloud-like structure of the alveoli means that there is a large surface area for gas exchange between the blood and the lungs, which increases the efficiency of the process, meaning the supplies of oxygen are constantly being replenished, and carbon dioxide is constantly being depleted.
WebThe exchange of gases occurs between the alveoli and blood in the capillaries that supply the lungs. The alveoli are adapted to provide a very large surface area for gaseous exchange: small... WebScore: 4.9/5 (44 votes) . The walls of the alveoli share a membrane with the capillaries. That's how close they are. This lets oxygen and carbon dioxide diffuse, or move freely, between the respiratory system and the bloodstream.Oxygen molecules attach to red blood cells, which travel back to the heart.
