The kidneys are a pair of bean-shaped organs on each side of your spine, under your ribs and behind your belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. It goes to the kidneys to extract water from the excretory system and put it back into the blood. Kidneys filter your blood. They eliminate wastes, control the body's fluid balance, and hang onto the right levels of electrolytes. All of the blood in your body passes through them quite a few times a day.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
