Heart and the Lungs
Terms in this set (13)
This pumps blood to the body.
These are two large respiratory organs inside the chest that take in O2 (oxygen), N2 (nitrogen) and CO2 (carbon dioxide) and release (lets out) CO2 (carbon dioxide) and N2 (nitrogen).
These are tiny sacs in the lungs that give oxygen to the blood (oxygenate) and take carbon dioxide from the blood (de-oxygenate).
This converts O2 (Oxygen) and food molecules into H2O (water), and CO2 (carbon dioxide), energy rich molecules.
This is where N2 (nitrogen), CO2 (carbon dioxide) and O2 (oxygen) travel down from the mouth and nose.
The lungs have 600 million of these.
This pumps the CO2 (carbon dioxide) blood into the lungs.
These are blood vessels that carry oxygenated blood away from the heart to the rest of the bodies.
The tiny sacs oxygenate (give oxygen to) the blood and remove the CO2 (carbon dioxide).
The passageway for the CO2 (carbon dioxide) and N2 (nitrogen) to leave the lungs and out the nose and the mouth when we exhale.
Oxygen (O2) leaves the blood cells and enters the _________of the body cells.
The O2 (oxygen) is transported here and converts the O2 (oxygen) and larger food molecules into energy-rich molecules, CO2, and water.
These are blood vessels that return blood to the heart.
