Heart attack is also commonly cause due to increase in rbc
Polycythemia or an increase in red blood cells
The number of RBC will increase
The percentage goes up. (Hematocrit is the percentage of red blood cells in a sample of whole blood, so if an elevated number of red blood cells is produced by your bone marrow, your hematocrit level should rise).
the hormone that produces red blood cells is erythropoeitin.
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.
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.
Beetroot contains high levels of iron and folate, which are essential nutrients for the production of red blood cells in the body. Consuming beetroot can help increase the production of red blood cells, which in turn improves oxygen transportation in the body.
Iron.
Erythropoietin is the hormone produced and released by the kidneys to increase formation of red blood cells. It also increases the oxegenation in the blood.
The number of red blood cells will increase but they will be proportional to the body size. In a way you can say that nothing will change. The numbers grow Just as the numbers of bone and muscle cells grow along with the increasing growth in body size.
