what about the effect of hypoxia on erythrocyte count?

Question

please quickly.......thanks

Answer 1

hypoxic condition stimulates our kidneys to produce a hormone called ERYTHROPOETIN which stimulates the bone marrow to produce more erythrocytes thus compensating for the stress

Answer 2

Hypoxia can cause elevation or increase of erythrocyte count. This is a coping reaction of the body trying to compensate for insufficient oxygen supply. In response to hypoxia, the hormone erthyropoietin, secreted by the kidneys, stimulates the bone marrow to produce red blood cells. The formation of red blood cells is known as erthyropoiesis.♥

Answer 3

The following from the source given explains it all:
Adult male, juvenile and pregnant rats were exposed to repeated hypoxia 8 h daily for 3-9 days in a low pressure chamber (altitude of 5000 m, pO2 = 11.3 kPa and 6000 m, respectively, pO2 = 9.89 kPa). The density distribution curves of the red blood cells (RBC) and the incorporation of 59Fe into cells of different density were determined. In the ontogenesis the density of RBC increases (median density on the first day of life 1.100 kg/l; on the 21st day of life 1.102 kg/l, adult rats 1.103 kg/l). The density difference between the 1st and 4th quartile in which 50% of the cells range was 0.010 kg/l for newborn and juvenile animals and 0.004 kg/l for adult ones. Exposure to hypoxia led iN the animals of the investigated age groups to a rise of the proporborns, 0.004 for juveniles, and 0.002 kg/l for adult rats. The cumulative distribution curves of 59Fe incorporation and density of RBC can be described by the equation (formula: see text). The value alpha characterizes the relation between density, on the one hand, and the maturity and age of cells, on the other. For control and hypoxic animals the following values for alpha have been calculated: for newborns 0.515 and 0.520, for juveniles 0.829 and 0.596 (p less than or equal to 0.01), and for adult rats 0.875 and 0.823. Juvenile animals from in regard to density similar heterogenic cells as newborns after hypoxia. It may be that ontogenetically older cell forming sites or clones are reactivated.

Answer 4

Short term, none.

Long term, the hematocrit will go up to try and compensate.
