There are many ways the alveoli can be considered well suited. Here are a couple:1. Thin for rapid diffusion.2. Large surface area for gas exchange.3. Rich blood supply for gas transport and good...
The site of gaseous exchange in mammals is the epithelium of the alveoli. To enable efficient gaseous exchange the alveoli have a number of adaptations to make them fit for purpose.
Since gaseous...
The amount of air that reaches the alveoli is 150 mlsless than the tidal volume. The reason for this is that this amount remains in an area called "dead space"
Oxygen moves into the blood because the partial pressure of oxygen is higher in air and lower in blood. Carbon dioxide moves out of the blood because the particle pressure of carbon dioxide is higher...
The alveoli are one of the reasons we are able to inhale/exhale 02 a co2. The alveoli fill up with oxygen that you breathe in. The oxygen from inside the alveoli then diffuses into the blood stream...
