respiration

co2 back || the path the better || flow of oxygen(from air or water) || in order to maximise up take of oxygen and match in to the body's needs,E.G in exertion || human's respirationplant's repiration
 * feature || explanaton ||
 * large surface area || maximises efficieucy of transfer ||
 * moist || gases must enter/leave via solution ||
 * in contact with blood cappillaries || blood carries oxygen away and brings
 * extremely thin || movement is via diffusion so the shorter
 * (possiby)mechanismto provide a steady


 * repiration in term of breathing is note that is one of 7 characteristic
 * aerabis repiration need oxygen so they take it from surrounding
 * by the gaseous exchange carbon dioxide get rid of it when aerobic repiration happen
 * external repiration is better because it extresses the entry of the oxygen
 * the places where it exchange of the gases occur is call repiratory surface
 * there is lot of kind of gases occur lungs for animal, gill for fish, skin for earth worm and cell surface for amoeba

AEROBIC RESPIRATION


 * 1) man are mostly living in organism
 * 2) the word aerobic means requiring air
 * 3) aerobis respiration could expressas a chemical equation

ANAEROBIC RESPIRATION
 * 1) different organism have several way to get energy from oxygen lesseffcient than aerobic respiration
 * 2) after exertion the body take some time to convert lactic acid
 * 3) single cell produce alcohol as a reslut of anaerobic respiration

RESPIRATION IN PLANTS
 * 1) they are unique ,they makes their own food by photosynthesis
 * 2) the plant produce oxygen which they release from the cell
 * 3) wrongly assume that plant don't need oxygen in the same way as other living organism
