How is the structure of the alveolus best adapted for its function?
Understand the Problem
The question is asking for an explanation of how the structure of the alveolus (the tiny air sacs in the lungs) is specially suited to its function in gas exchange. This involves discussing features like surface area, thin walls, and proximity to capillaries.
Answer
The alveolus is adapted with thin, moist walls, rich blood supply, and a large surface area for efficient gas exchange.
The alveolus is adapted for gas exchange with thin, moist walls for efficient gas diffusion, rich blood supply to maintain a high diffusion gradient, and a large surface area to volume ratio for maximum diffusion efficiency.
Answer for screen readers
The alveolus is adapted for gas exchange with thin, moist walls for efficient gas diffusion, rich blood supply to maintain a high diffusion gradient, and a large surface area to volume ratio for maximum diffusion efficiency.
More Information
The alveolus maximizes its ability to exchange gases through its structural adaptations, vital for respiratory efficiency, and significantly impacts the body's oxygen and carbon dioxide transfer.
Tips
A common mistake is not acknowledging the importance of all adaptations (e.g., moist walls, thinness, and blood supply); each plays a crucial role in effective gas exchange.
