How is the blood in the lungs purified?

Low he travels through the human body and transmits energy to various organs as well as absorbs some impurities. Unclean blood travels through the body and enters the lungs. The human chest has two sac-like organs called the lungs. It is connected to the trachea by the nose. The main function of the lungs is to purify the blood. It’s like knowing how this works.

The air we breathe through the nose goes to the lungs. The trachea is divided into several branches in the lungs. Eventually a very fine tube is formed. Tubes that carry impure blood to the lungs also become subtle by dividing.

Thus the blood vessels and airways form a web. Spherical cells are located at the ends of blood vessels. These cells, like grape clusters, carry oxygen from the airways into the bloodstream. Simultaneously the carbon dioxide in the blood pushes into the airways. The lungs contain millions of cells that are invisible to the naked eye. The lungs keep the body's blood clean by constantly working.
