Answer:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.

This answer to this question is Paramecia, cilia
        
             
        
        
        
Explanation:
when it's fully charged it's a ATP and when it's runs down it's ADP
and there are times when the cells need more energy and splits off another phosphate so it goes from ADP adenoside di-phosphate, to AMP, adenosine mono-phosphate  
and there you have it

<span>Cilia and flagella are made up of microtubules covered by
plasma membrane and they projection from the cell. Thus, cilia are flagella are
motile and designed to move substances over or around the cell and they can as
well move the cell itself. In eukaryotes, they are conserved in their polypeptide
composition, structure and function as motile and sensory organelles.</span>
