WebInternal respiration is gas exchange that occurs at the level of body tissues ( Figure 22.4.3 ). Similar to external respiration, internal respiration also occurs as simple diffusion due to a partial pressure gradient. However, the partial pressure gradients are opposite of those present at the respiratory membrane.

Webad 1 - Deoxygenated blood is brought to the alveoli. ad 2 - Diaphragm and intercostal muscles cause the volume of the lungs to increase and decrease in volume by CONTRACTIONS. This causes ventilation to occur. This in turn ensures a supply of high oxygen and low carbon dioxide AIR to the alveoli. Click the card to flip 👆. WebThe alveolar membrane is the gas exchange surface. Gas exchange in the lung. When you inhale oxygen, it enters the lungs and travels to the alveoli.
