Concept Map: Gas Exchange
Amanda Egert; Kimberly Lee; and Manu Gill
Image Description
This concept map illustrates the steps of gas exchange. The flow is as follows:
- Respirations
- Inhalation of air
- Expiration to atmosphere
- Alveoli
- Pulmonary capillaries
- Diffusion
- Hemoglobin carrying capacity
- Perfusion
- Delivery of oxygen and nutrients
- Cells lining alveoli
- Cellular uptake of oxygen and nutrients
- Cellular metabolism and energy
- Waste products – carbon dioxide
- Capillaries carrying waste out of cell through perfusion
- Expiration
