Why do you need cellular respiration?

Answer 1

Cells have to remove waste to grow and develop. There for if they didn't remove useless waste, then you would still be a single cell.

Answer 2

Wastes are excreted by the body as it recognizes them as useless to the human body and/or harmful. If gasses excreted by the lungs, toxins excreted by the kidneys, chemicals excreted by the skin, or substances excreted by the bowel are maintained in the body, they can disrupt the balance and functions of various and multiple body systems which can lead to organ failure and death.

Answer 3

Your body has to get rid of carbon dioxide because it's poisonous to your body.

Carbon dioxide in solution exist in an equilibrium with carbonic acid, bicarbonate and carbonate. If you couldn't exhale CO2 carbonic acid would build up in your blood and tissues causing acidosis, which is a very dangerous situation indeed.

Answer 4

the build up of wastes in the human body should be prevented. some wastes like urea and even salt, cause harm to cerain organs, these are examples of harmful wastes. on the other hand we have undigested food, now, if we do not excrete, will our body be able to continue taking in food? we need to give out the substances so that the same cycle can take place again. the kidneys play an important role in the excretion of harmful wastes

Answer 5

You have three types of waste in your body. Waste of food digestion. Waste of metabolism other than carbon bi oxide and carbon bi oxide. Waste of food digestion pass as fecal matter. Waste of metabolism like urea pass via your kidneys. Carbon bi oxide is passed via your lungs. Is it possible to collect the fecal matter even for a year in your body? The urea is very toxic to the brain. You have to eliminate it vigorously. You have a very special system for the same. Excretory system. You have very important system to eliminate the carbon bi oxide and to consume the oxygen. Pulmonary system is there to handle this along with right side of the heart. Then skin is also important source to eliminate certain types of waste.

Answer 6

You need cellular respiration so as to create energy which will be used for other cellular process. The type of energy created is known as ATP.

Answer 7

Waste is another word for toxins. These will poison the body if the levels are too high.
