WebbInternal 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.
