Through your MOUTH and your NOSE.
maybe your question goes this way..."how does oxygen enter the blood from the lungs?"Two types of blood vessels carry blood throughout our bodies: The arteries carry oxygenated blood (blood that has received oxygen from the lungs) from the heart to the rest of the body. The blood then travels through the veins back to the heart and lungs, where it receives more oxygen.
The right atrium of the heart receives oxygen-poor blood from the body.
Blood gets oxygen in the cells. This is part of the body system.
because the body needs oxygen, which is received from the heart to perform all activities
Because your muscles need oxygen and oxygen is in the blood so the heart pumps bloid around the body
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.
