The contractile vacuole is basically a water bubble within the endoplasm of A. proteus. It's function is to regulate the water content of the cell. It is also a means of excreting its waste from the cell (out through the cell membrane) VIA diffusion. ... Without the contractile vacuole, the amoeba may burst.

This small protozoan uses tentacular protuberances called pseudopodia to move and phagocytose smaller unicellular organisms,(which may be greater in size than of amoeba), which are enveloped inside the cell's cytoplasm in a food vacuole, where they are slowly broken down by enzymes.

Describe what happens to the air in the lungs when we breathe. What happens to the concentration of
Otrada [13]

When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.

Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.

Hope this helped, even if it helped a tiny bit. :)
