Oxygen in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)
The ocelot breathes through its nostrils like other mammals. When it inhales, air enters through its nostrils and passes through the nasal passages into the lungs, where oxygen is exchanged with carbon dioxide. The ocelot then exhales, releasing carbon dioxide from its lungs through the same pathway.
after the oxygen from the air enters the lungs,the oxygen gets sent to the heart and then travels through the arteries with the blood.
The lungs (two) expand as air enters through the nose to the trachea to the main bronchi (two, split from one main bronchus) and down into the lungs. The diaphragm, a muscle band below the lungs, relaxes and contracts to assist in inhalation and exhalation.
Oxygen enters the blood stream through the air sacs in you lungs.
