Gas exchange in the lungs We need to get oxygen from the air into the blood, and we need to remove waste carbon dioxide from the blood into the air. Moving gases like this is called gas exchange.

Definition Gas exchange is the process by which oxygen is transferred from the atmosphere to bodily tissues for use in metabolism; and the gas produced by metabolism, carbon dioxide, is transferred from tissues to the atmosphere.
H.6.7: Effects of High Altitude on Gas Exchange. A person living at high altitude has to deal with a number of challenges regarding gas exchange in the lungs. One of the main problems is the change in atmospheric pressure as you go higher in altitude.
Since both human and orcas are mammals, the killer whale’s internal circulation system and gas exchange system are much like the human’s internal circulation and gas exchange system. Orcas have lungs, need oxygen but for a longer period and closed double circulatory system just like humans do.
Features of gas exchange surfaces in humans (4) -Large surface area -The presence of millions of alveoli in the lungs provides a very large surface area for gaseous exchange. -Thin surface (epithelium) -only a 2 cell layer, at the most, separating the air in the alveoli from the blood in the capillaries.
