through their lungs
the oxygen releases carbon dioxide
Oxygen enters your nose,then goes through the trachea,to the bronchi,and last to your lungs.
Oxygen passes into the body through absorption in the lungs.
from your lungs it is transfered to the heart then pumped through the body
Your lungs circulate oxygen every time you inhale and exhale. They travel through your body when you inhale to the lungs and the lungs store the oxygen, and as you exhale, carbon dioxide from the air is released.
The air enters through the mouth or the nose and is pulled down through the windpipe into the lungs. From the lungs, the oxygen molecules are dissolved in the alveoli and enter the red blood cells in the capillaries of the lung. From the capillaries, they travel to the heart and push oxygen through the body.
Through the mother's lungs into her bloodstream, then across the placenta and through the umbilical cord to the fetus.
gas exchange occurs in the alveoli in the lungs where deoxygenated blood gets oxygen, that blood then goes to the heart and is pumped through the body through the aorta and the arteries, which brings oxygen to the body cells.
through their lungs
On a very basic level, it is absorbed through capillaries in the lungs into red blood cells in the the blood stream.
Lungs
the oxygen in your blood comes from the air you breath in . It goes in through your mouth into the lungs and the oxygen gets taken out from the lungs into the cappilaries.
they travel through the capillary which exchanges them to carbon dioxide
The red blood cells in your body contain oxygen and carbon dioxide. So, as the red blood cells travel through your bloodstream, the oxygen travels through to your heart, then your lungs, along with the oxygen.
