Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.
Superior Vena Cava: All blood on the right side of the heart is CO2: Carbon Dioxide. It's O2 (Oxygen) starved.
Oxygen that has been used by your body during respiration is converted into carbon dioxide as a waste product. The carbon dioxide is then transported back to the lungs, where it is exhaled out of the body when you breathe.
By mass Oxygen
First you breath it in and then it goes through you blood stream dropping off oxygen molecules and picking up carbon dioxide all through the body and then it goes to the lungs to get more oxygen and drop off the carbon dioxide so it can be exhaled.
Oxygen is not stored in the body for long periods of time. It is continuously being used by the cells to produce energy through processes like cellular respiration. The body relies on a constant supply of oxygen from the lungs to meet its metabolic needs.
Through your MOUTH and your NOSE.
oxygen enters the body when you breathe entering through the nose or the mouth. the red blood cells carry oxygen throughout the entire body.
Oxygen enters the bloodstream through the alveoli in the lungs. When you breathe, oxygen from the air diffuses across the thin walls of the alveoli into the surrounding capillaries, where it binds to hemoglobin in red blood cells for transport throughout the body.
Blood picks up oxygen and releases carbon dioxide in the lungs.
Blood picks up oxygen and releases carbon dioxide in the lungs.
By breathing, Oxygen is part water.
After entering it takes the left pump after entering
Oxygen enters the body by travelling into the lungs, it then diffuses through the alveoli cell wall into the body's biggest artery, the aorta.
Oxygen first enters your body through your respiratory system, specifically through your nose or mouth, where it is inhaled into your lungs. In the lungs, oxygen is transferred from the air you breathe into your bloodstream to be circulated throughout your body to provide energy to your cells.
Raw materials and harmful wastes enter and exit the cells in your body by blood, the red blood carry oxygen from lungs to the body cells.
Pollution enters the system by respiration. When you breathe in your body uses the oxygen in the "air". But when pollution is in the "air", your body takes that in and enters the Ovules of the lung and enter your blood stream.
Oxygen enter the capillaries by diffusion due to difference in oxygen concentrations.
