Internal respiration occurs when respiration takes place in each cell. Oxygen is used in the mitochondria of the cell to help release energy in food molecules. Because this happens inside the cell it is called internal respiratiin.

External respiration is the act of breathing . We are moving air that contains oxygen into the lungs where it will be carried by the bloodstream to each cell Then carbon diixide is released as a waste product from burning the fuel. It travels back to the lungs to be expelled.All animals carry out both types of respiration.

Plants only have internal respiration. Oxygen is brought in through a leaf's stoma ( holes in the leaf) to be used in the mitochondria. The carbon dioxide produced exits the leaf thru the stoma.

Almost all living things use this internal '' respiration . ( there are exceptions)But only animals use external respiration. Animals breathe, plants dont
