What is an example of waste product?
C02 expelled from the lungs urea expelled in the urinefeces in general
How do mammals breathe?
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.
What is the physical act of moving air into and out of the lungs called?
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.
What is the last noise that you hear from a dying person that sounds like snoring?
It is sometimes called the "death rattle" as the last air is expelled from their lungs.
How is carbon dioxide let out of the body?

What are the tiny hairs called that sweep outr dirt in the 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.
When the lungs take in oxygen they are functioning to collect oxygen for the body to use When air is expelled from the lungs they are functioning to?
remove waste from the body

remove waste from the body
Which organ in the body gets rid of carbon dioxide?
Carbon dioxide is expelled from our lungs.
What are the slimy secretions in the lungs that protect it from dust and infectious agents?
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.
What is the process called when the lungs are getting bigger and smaller?
The process of the lungs getting bigger and smaller is called respiration, specifically during inhalation and exhalation. During inhalation, the diaphragm contracts and moves downward, expanding the chest cavity and allowing air to enter the lungs. Conversely, during exhalation, the diaphragm relaxes, the chest cavity decreases in size, and air is expelled from the lungs. This cycle is essential for gas exchange in the body.
What is the lower opening of the digestive tract?
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.
