In which structure does gas exchange occur?
Gas exchange occurs in the alveoli of the lungs. These tiny air sacs are surrounded by capillaries where oxygen from the air can enter the bloodstream and carbon dioxide can be removed from the blood.
Gas and nutrient exchange occur in the?
Gas exchange occurs in the alveoli of the lungs, where oxygen from inhaled air diffuses into the bloodstream and carbon dioxide diffuses out. Nutrient exchange occurs in the small intestine, where nutrients from digested food are absorbed into the bloodstream to be transported to cells throughout the body.
Why do plants need stomata and air space?
The air space keeps the stomata moist so that transpiration and gas exchange can occur. The gas exchange in the stomata needs to take place so that photosynthesis can occur. So without the air space you have no stomata, and without the stomata you have no photosynthesis which is how plants obtain their food.
What conditions must exist before a marketing exchange can occur?
For a marketing exchange to occur, there must be two parties involved - a buyer and a seller. Both parties must have something of value that the other party desires, such as a product or service.

Where does gas exchange occur in fetal pigs?
lungs
Where in the respitory tract does gas exchange occur?

Is gas exchanged in the pleura?
Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
What surrounds the alveoli in the lungs to allow gas exchange to occur?
Capillaries
Where in the repiratory system does gas exchange occur?
Between the avioli and the lungs.
How does gas exchange occur?
Gaseous exchange takes place when the volume of the chest cavity is increased or decreased.
