It increases up to 3 times normal,
most of flow to muscles with some decrease to internal organs.
They help because they keep the blood flowing properly around the body:)
They are broken down in the liver.
For endurance athletes especially because of the oxygen carrying potential of each red blood cell. The more red blood cells they have, the more oxygen being delivered to their cells during high intensity workouts. This is the whole basis of blood-doping; Athletes train in a high altititude where their body adapts to the low oxygen content in the air by producing more red blood cells. These red blood cells are then extracted and stored, and when needed are reinjected.
The cells in the bloodstream include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen to tissues, white blood cells help fight infections, and platelets aid in blood clotting.
White blood cells have a nucleus and red blood cells don't.
Polycythemia or an increase in red blood cells
It loses oxygen!
After old red blood cells rupture, the fragments are broken down by the body's immune system and recycled for the production of new red blood cells.
The spleen stores extra red blood cells and acts as a reservoir, releasing them when needed, such as during times of increased demand like exercise or injury.
well,red blood cells mean that your healthy,but to much exersize gives you blue blood cells witch is bad if you have too much
this mostly happens with multi-cellular organisms and red blood cells. Red blood cells lose their nucleus.
Erythropoiesis (making red blood cells) and the synthesis of other blood cells.
They help because they keep the blood flowing properly around the body:)
Red blood cells are made by the marrow.
They are broken down in the liver.
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.
That is virtually impossible but if it did we would have problems with our bloodstream
