Oxygen transport
Oxygen transport in the body primarily involves red blood cells, which contain a protein called hemoglobin. When you breathe in, oxygen from the air enters your lungs and passes into your bloodstream. Hemoglobin binds to the oxygen and carries it through the bloodstream to tissues and organs. This process is essential for providing the energy cells need to function. When the red blood cells reach areas where the oxygen levels are low, they release the oxygen, allowing it to be used by cells. Meanwhile, carbon dioxide, a waste product, is transported back to the lungs to be exhaled.

Oxygen transport refers to how oxygen moves from the air we breathe into our bloodstream and then to various tissues in the body. When we inhale, oxygen enters the lungs, where it crosses into tiny blood vessels. Here, red blood cells pick up the oxygen and carry it throughout the body. This process is crucial because oxygen is essential for producing energy in our cells. As the cells use oxygen, they release carbon dioxide, which is then transported back to the lungs to be exhaled. This cycle supports vital functions and overall health.
