Please tell us where you read or heard it (including the quote, if possible). The oxygen gets in the body through the respiration process. French oxygène, from Greek oxys, adjective, acidic, literally, sharp + French -gène -gen; akin to Latin acer sharp — more at edge. In this process, plants transform CO2 and water into sugars to use in their metabolism, help them to grow and to provide food for other organisms. Oxygen cycle, along with the carbon cycle and nitrogen cycle plays an essential role in the existence of life on the earth. Oxygen and is present in many organic compounds.

It is an important parameter for managing patients in a clinical setup. Simple diffusion is a type of passive transport which, as the name suggests, is simply the movement of solute which occurs when its electrochemical potentials on the two sides of a permeable barrier are different..
