GENERAL HISTOLOGY

Detailed explanation-1: -Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.

Detailed explanation-2: -Cellular respiration uses organic molecules from food (for example, the sugar glucose) and oxygen to produce energy that is stored in the molecule adenosine triphosphate (ATP), as well as heat. Cellular respiration also produces carbon dioxide and water.

Detailed explanation-3: -Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

Detailed explanation-4: -When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.

Detailed explanation-5: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
