Web17 Jan 2024 · External respiration is the formal term for gas exchange. It describes both the bulk flow of air into and out of the lungs and the transfer of oxygen and carbon dioxide into the bloodstream through diffusion. While the bulk flow of air from the external environment happens due to pressure changes in the lungs, the mechanisms of alveolar gas ... Web25 Nov 2014 · OXYGEN goes into your bloodstream and you offload nasty CARBON DIOXIDE. ALVEOLI carry out GAS EXCHANGE in the body. 1) The lungs contain millions of little air sacs called ALVEOLI where gas exchange happens. 2) The blood passing next to the ALVEOLI has just returned to the lungs from the rest of the body, so it contains lots of …

Gas exchange is required because: The human body is composed of many living cells that undergo aerobic respiration. Humans are endothermic organisms, meaning they need to maintain a constant body temperature and have a high metabolic rate. swr302 finalWeb30 Jul 2024 · Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. swr302 pt1WebGas Exchange in Fish. The water surrounding a fish contains a small percentage of dissolved oxygen. The fish uses a special gas exchange organ (gills). It has a large surface area and a short distance for gas exchange to the blood capillaries.
