Detailed explanation-1: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Detailed explanation-2: -“Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.”

Detailed explanation-3: -The oxygen we inhale is used to breakdown glucose into carbon dioxide and water. Energy is released in the process. The breakdown of glucose occurs in the cells of an organism (cellular respiration). If the food is broken down with the use of oxygen, it is called aerobic respiration.

Detailed explanation-4: -The transfer of oxygen from the outside environment to cells within tissues, as well as the removal of carbon dioxide in the opposite way, is referred to as respiration. It is a biological reaction that takes place within the cells of living organisms.

Detailed explanation-5: -Respiration is the process that all living things go through to create the energy they need to live. This happens in the cells so it is also called cellular respiration. It usually involves exchanging two gases-oxygen and carbon dioxide. The cells take in oxygen and release carbon dioxide.
