Actually the nose
During exercise, the body requires more oxygen, leading to an increase in red blood cell production to transport oxygen to working muscles. This can improve overall oxygen delivery and increase endurance during physical activity.
Well as you might know: Organism > organ systems > organs > tissue > cells > (atoms and molecules and such) For the cell to function it requires oxygen. If the cell doesn't function the tissue fails. Then the organs, organs systems and then the organism dies.
== == cell organs
Yes, it has it specific duties. Mostly to carry oxygen and glucose around the body to organs which need it.
Red cells carry oxygen around the body. Exercise increases the demand for oxygen, so the body produces more red cells, to carry more oxygen to the tissues.
Your red blood cell count will increase in response to the body's increased demand for oxygen as a result of long-term aerobic exercise.
It increases the surface area of the cell to make exchange of oxygen and carbon dioxide faster and easier
Red blood cells carry oxygen to all areas of the body. Oxygen is vital to all of the body's organs and functions.
The heart has to pump oxygenn aroound the body faster because when you excercise your body is using up oxygen quicker than normal. The pumps get harder and faster.
oxygen debt
hemoglobin is found in the cell and it is used to carry oxygen to different organs in the body
when we excercising, tissue generates heat.those heat would increase the temperature of the neighboring cell, that exercise and need more energy. thus, more oxygen is needed, making the graph shift to the right because hemoglobin release oxygen faster to accord the increasing demand during exercise.
