The primary function of the respiratory system is to take in oxygen and eliminate carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli.

Frequently Asked Questions
What system takes in oxygen and releases carbon dioxide?
Your body constantly needs oxygen in order to function and needs carbon dioxide to be removed. This system takes care of both. When you inhale, you take in much-needed oxygen from the air. When you exhale, you release carbon dioxide, which is a waste product. The system that... See full answer below.
How is oxygen released back into the atmosphere?
Respiration, combustion and decomposition are three other ways that CO 2 and/or oxygen is released back into the atmosphere. Another biogeochemical cycle, the hydrogen cycle, connects some of the pathways in nature that are involved in the carbon and oxygen cycles.
What is the function of oxygen in the respiratory system?
The rate at which oxygen is used by the body is one measure of the rate of energy expended by the body. Breathing in and out is accomplished by respiratory muscles. The function of the respiratory system is to move two gases: oxygen and carbon dioxide.
When do you inhale, you release carbon dioxide?
When you inhale, you take in much-needed oxygen from the air. When you exhale, you release carbon dioxide, which is a waste product. The system that...
