Approximately 20% of inhaled air is oxygen and approximately 15% of exhaled air is oxygen.
I know that doesn't answer your question fully, but I hope it helps you gain a little more insight.
Animals that breath water use gills to extract oxygen from the water and absorb it into the blood for distribution throughout their bodies.
The oxygen in each breath is circuited to the lungs where the alveoli absorb the oxygen and passed to the blood cells. The blood cells enter the heart where the oxygenated blood is circulated where needed.

You breath in and get fresh oxygen.
Raccoons breath in oxygen just like any other mammal. They inhale oxygenated air through the mouth and nose into the lungs. The lungs absorb the oxygen and excrete carbon dioxide.
No, the human body needs a balanced mixture of gases to function properly. While oxygen is essential for respiration, breathing in only oxygen without other gases like nitrogen would lead to serious health issues such as oxygen toxicity.
Both! your body only keeps the oxygen though and when you breath out the carbon ddioxide comes out
An individual unable to absorb oxygen into the body is called dead, and is unable to perform cellular respiration.
Carbon dioxide
They absorb oxygen to carry to the rest of your body
You don't only "breath in air, and breath out air," You breath in Oxygen and let out Carbon Dioxide. Passes to the diaphragm and the lungs, inhale oxygen, it goes through your body, exhale Carbon Dioxide, From which the body has made when inhaled.
the blood absorb oxygen in the lungs(cappilaries)
