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: -When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.

Detailed explanation-3: -A physical process in which an organism takes in oxygen is called inhalation. Breathing is defined as the process that moves air in (inhalation) and out of the lungs (exhalation). Respiration is the breakdown of food molecules in the presence of oxygen with the release of carbon dioxide, water, and energy.

Detailed explanation-4: -Inhalation and exhalation is called breathing. During inhalation, air is taken into the body and after oxygen is absorbed into the blood it is exhaled into the atmosphere. Breathing is a part of respiration.

Detailed explanation-5: -Breathing means taking in air rich in oxygen and giving out air rich in carbon dioxide with the help of respiratory organs. The taking in of air rich in oxygen into the body is called inhalation and giving out of air rich in carbon dioxideis known as exhalation.
