Answers with Surety of 100% Pass Mark



Alveolar air volume - 🧠 ANSWER ✔✔amount of air that reaches alveoli for gas

exchange (approx. 350 ml. For adult male) Tidal volume minus dead space


Dead air space - 🧠 ANSWER ✔✔anatomic dead space are structures that hold air

but but can't participate in gas exchange. Physiologic dead space are alveoli or

capillaries destroyed by disease
