Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)
Oxygen enters our body through the process of respiration. When we inhale, air containing oxygen enters our lungs. The oxygen then diffuses from the air sacs in the lungs into the bloodstream, where it is carried by red blood cells to tissues throughout the body.
Oxygen enters your body through the lungs during the process of breathing. The air you inhale contains oxygen, which is then absorbed into the bloodstream in the lungs and transported to cells throughout the body.
nose or mouth
Oxygen enters the body through the respiratory system, specifically through the process of breathing. When we inhale, oxygen is taken in through the nose or mouth, travels down the trachea, and enters the lungs. In the lungs, oxygen is transferred to red blood cells in the bloodstream and carried to the cells throughout the body. The oxygen is then used in cellular respiration to produce energy for the body's functions.
Oxygen enters the body through the respiratory system, specifically through the process of breathing. When we inhale, oxygen is taken in through the nose or mouth, travels down the windpipe, and enters the lungs. In the lungs, oxygen is absorbed into the bloodstream through tiny blood vessels called capillaries. The oxygen-rich blood is then pumped by the heart to all the cells in the body, where it is used for energy production and proper functioning.
Oxygen rich air enters the body through the lungs.
The respiratory system supplies oxygen to the blood through the process of breathing. When we inhale, oxygen from the air enters the lungs where it is absorbed into the bloodstream and then circulated throughout the body to supply cells with the oxygen they need for energy production.
When you inhale, oxygen enters your lungs and diffuses into your bloodstream through tiny air sacs called alveoli. The oxygen is then carried by red blood cells in the blood vessels to different tissues and organs in your body. Once the oxygen reaches the cells, it is used in cellular respiration to produce energy.
