Detailed explanation-1: -Exhalation of carbon dioxide from the body is an example of excretion.
Detailed explanation-2: -Excretion is the process of removing waste products from the body, while respiration is the process to remove energy from food. Respiration and excretion are also processes that plants go through.
Detailed explanation-3: -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-4: -Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.
