Flashcard: Fundamentals of Respiratory Gas Exchange — 10 carte

Alveolo-capillary exchange — process?

O2 enters blood; CO2 leaves blood.

Oxygen diffusion — direction?

From alveoli to blood and tissues.

CO2 diffusion — opposite?

From tissues to alveoli.

Gas diffusion — principle?

High to low partial pressure.

Dalton's Law — partials?

Each gas exerts independent partial pressure.

Oxygen transport — role?

Deliver O2 from lungs to tissues.

CO2 movement — driven by?

Partial pressure gradient.

Gas exchange zones?

Between alveolar air and venous blood.

Circulatory system — function?

Transport gases, maintain gradients.

Partial pressure — importance?

Drives diffusion, determines gas movement.
