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.
In the bloodstream
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 lungs diffuse oxygen into the bloodstream. Oxygen from the air we breathe is absorbed into the bloodstream through the walls of the alveoli in the lungs, where it is then carried by red blood cells to be delivered to the body's tissues.
The respiratory system.
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.
You breathe in through your nostrils or mouth, which allows air to enter your respiratory system and reach your lungs where oxygen is absorbed into the bloodstream.
American Martens, like other mammals, breathe in oxygen through their lungs. They have specialized respiratory systems that allow them to extract oxygen from the air and deliver it to their body tissues through their bloodstream.
The bloodstream is the roads, the railways, and the airports of the body. Everything that goes from one part of the body to another enters the bloodstream at some point.
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.
