NEET BIOLOGY

Detailed explanation-1: -When we breathe, the respiratory system takes in oxygen and sends out carbon dioxide. The cells in our bodies need fresh oxygen to stay alive. As cells do their jobs, they make and give off carbon dioxide. This exchange of oxygen and carbon dioxide is called respiration.

Detailed explanation-2: -The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

Detailed explanation-3: -What Are the Parts of the Respiratory System? The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs.

Detailed explanation-4: -The air contains oxygen that crosses the lung tissue, enters the bloodstream, and travels to organs and tissues. Oxygen enters the cells where it is used for metabolic reactions that produce ATP, a high-energy compound. At the same time, these reactions release carbon dioxide as a by-product.
