Question

We 'breathe out' to remove waste product and
from our body.​

Answer 1

Answer:

Here is your answer

Explanation:

Excretion gets rid of carbon dioxide, water, and other, possibly harmful, substances from your body. Your lungs excrete carbon dioxide as you breathe out, your kidneys filter out nasties to produce urine, removing nitrogen waste from your body, and your skin sheds excess salt through sweat.

Answer 2

Answer:

Everyday functions of the body like digesting your food, moving your muscles or even just thinking, need oxygen. When these processes happen, carbon dioxide is produced as a waste product. The job of your lungs in this system is to provide these processes with oxygen and to get rid of the waste gas, carbon dioxide.
