Thanks for your questions
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.
The physiological definition of respiration differs from the biochemical definition, which refers to a metabolic process by which an organism obtains energy (in the form of ATP) by oxidizing nutrients and releasing waste products. Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.
In animals with lungs, physiological respiration involves respiratory cycles of inhaled and exhaled breaths. Inhalation (breathing in) is usually an active movement. The contraction of the diaphragm muscle cause a pressure variation, which is equal to the pressures caused by elastic, resistive and inertial components of the respiratory system. In contrast, exhalation (breathing out) is usually a passive process. Breathing in, brings air into the lungs where the process of gas exchange takes place between the air in the alveoli and the blood in the pulmonary capillaries

Respiration is a processed used by all cells to turn fuel, which holds stored energy, into a usable form.
Explanation:
- The product of respiration is a molecule called ATP, which can simply use the energy stored in its phosphate bonds to power chemical reactions the cell needs to exist.
- Aerobic respiration is respiration which uses oxygen as a reactant.
- Aerobic respiration is much more efficient, and produces ATP very much quickly, than anaerobic respiration (respiration without oxygen).
