Oxygen enters via the lungs.
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.
The respiratory system.
Oxygen enters the body through the respiratory system, specifically through the lungs. Inhaled air travels through the trachea and into the lungs where it is diffused into the bloodstream through tiny air sacs called alveoli. The oxygen is then carried by red blood cells to various tissues and organs in the body.
Oxygen diffuses from the alveolus into the blood capillary due to the concentration gradient - from high to low concentration. This process allows oxygen to enter the bloodstream and be transported to the body's tissues for utilization.
Oxygen enters the body through the respiratory system. It is inhaled through the nose or mouth, travels down the trachea, enters the lungs, and then diffuses into the bloodstream through tiny blood vessels called capillaries in the lungs.
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.
