This card summarizes the adaptations of alveoli for efficient gas exchange: large surface area, thin walls, good blood supply, and ventilation.
Tato karta shrnuje adaptace plicních sklípků (alveoli) pro efektivní výměnu plynů: velký povrch, tenké stěny, dobrá zásoba krve a ventilace.
| Front | Alveoli adaptions 3.1.1(b) |
|---|---|
| Back | - large SA (folded shape) - thin layers (only single epithilel cell thick) - good blood supply (constant flow of CO2/O2 through blood) - good ventilation (breathing moves air in/out, steep conc gradient) |
