without it, it is impossible to get oxygen in and carbon dioxide out.
As your diaphragm or intercoastal muscles contract the size of the lungs increases. This creates a pressure difference between your lungs and the surrounding atmosphere. By increasing the size of the lungs you create a low pressure environment in the lungs by expanding the same amount of gas to a larger area. this pressure difference doesn't have to be much 1mmhg is more then enough, the main thing is just that you need a difference in preasure. Air flows from high preasure to low preasure, so by decreasing the preasure in the lungs air flows into the lungs. as you breath out you make the lungs smaller by relaxing the muscles and diaphragm, making the volume in the lungs decrease, thus increasing the preasure and moving the air from inside the lungs out to the surrounding atmosphere.
Oxygen in the lungs attaches to red blood cells and is carried through the bloodstream to all parts of the body. The oxygen is released from the red blood cells and picked up by tissues that need it for energy production. Carbon dioxide, a waste product, is picked up by the blood and transported back to the lungs to be exhaled.
The lungs remove carbon dioxide from the bloodstream. As blood circulates through the lungs, carbon dioxide diffuses from the blood into the lungs to be exhaled out of the body.
The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
Yes, the lungs take in oxygen from the air we breathe and transfer it into the bloodstream through tiny blood vessels called capillaries. Oxygen-rich blood is then carried to the rest of the body to supply cells with the oxygen they need for energy production.
You need your lungs to breathe. Without lungs, you'd be dead.
You need lungs to breathe.
Of course. They need lungs to breathe.
snakes and frogs need lungs to help them breath becuse when they grow they don't grow with gills they grom with lungs instead.

lungs are tubes that transfer blood from your heart to your lungs and other parts of your body. (doesn't need to be improved)
your lungs
Lungs.
No, you need lungs for that.
lungs
Yes, they do have lungs as they need to breath air.
