Mammals breathe using organs called lungs. They take air in and the oxygen is exchanged for carbon dioxide in small organelles called alveoli. This carbon dioxide is then expelled.
The physical act of moving air into and out of the lungs is called ventilation. It involves inhalation, where air is drawn into the lungs, and exhalation, where air is expelled from the lungs. This process is essential for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
It is expelled from the lungs when you breath out.
It is sometimes called the "death rattle" as the last air is expelled from their lungs.
The tiny hairs in the lungs that sweep out dirt and mucus are called cilia. These hair-like structures help to keep the airways clear by moving debris upwards towards the throat where it can be swallowed or expelled.

Carbon dioxide is expelled from our lungs.
The slimy secretions in the lungs that protect it from dust and infectious agents are called mucus. Mucus traps particles like dust and pathogens, preventing them from entering deeper into the lungs. The cilia in the respiratory tract then move the mucus upwards so it can be expelled from the body.
The lower opening of the digestive tract is called the anus. It is where waste material from the body is expelled during the process of defecation.
alveoli. These are tiny air sacs in the lungs where oxygen from inhaled air enters the bloodstream and carbon dioxide from the blood is expelled into the lungs to be exhaled.
