Question and answer
Where does air enter and leave our body?
Air enters our lungs so we can obtain oxygen to fuel our cells in our body. Air leaves the lungs because when oxygen enters the cells waiting in the lungs, the bi-product the cell makes when it absorbs the oxygen is carbon dioxide, [ which is exhaled from the lungs. ]

User: Sorry, but it does not answer my question.

Weegy: it eneter on our nose



User: What if I say that it enters or leaves our body through the lungs? Do you agree with me? Explain.

Weegy: yes i would agree here is the explanation :air enters our body by negative pressure breathing, wherein the diaphragm (muscle separating digestive and respiratory ..uhm... [ sections) contracts, thus increasing the space above (that is, the lung cavity) and so "pulling" the air into the lungs through the wind pipes and nostrils. ]

You are talking to yourself as a user and an expert? Do you have two windows open? And you rated yourself good? You might want to read the blog. This is considered cheating and is also the reason why so many of us are answering so many questons and not getting paid for them.
