Best Answer

When your kidneys sense a low blood oxygen level the adrenal gland secretes erythropoietin. This signals the bone marrow to synthesize more red blood cells. Also commonly known as EPO.

What effect does it has on the hematocrit if the kidneys respond to a decrease in oxygen?

a decrease in oxygen will result with an increase of red blood cell production (more carriers for hemoglobin to compensate for the lower levels of oxygen). The kidneys produce erythropoietin that stimulate RBC production.


What happen to kidney if blood oxygen decrease?

I believe it causes the kidneys to secrete more erthyropoietin, a hormone that stimulates the synthesis of red blood cells in bone marrow.


What role do the kidneys play in erythropoiesis?

the kidneys detect low levels of oxygen in the blood


Oxygen levels in the sea decrease with depth. how do deep sea divers get there oxygen?

plants


Which effect does a decrease in sunlight have on a pond ecosystem?

An increase in oxygen levels


A decrease in the blood's ability to transport oxygen is called what?

The correct name for low levels of oxygen in the blood is hypoxaemia. Low levels of oxygen in the body tissues is called hypoxia


What occurs if the oxygen flow to the body is inadequate?

If this process is inadequate, oxygen levels in the blood decrease, and the patient may need supplemental oxygen.


What happens to breathing when oxygen levels decrease?

Breathing speeds up, but the breaths are shallower.


What is the hormone that kidneys will secrete to stimulate red blood cell production?

Erythropoetin from the mesangial cells of the glomerulus in the nephron of the kidney. These cells detect altered levels of oxygen in the blood plasma.


Explain how changes in the alveolar structure cause a decrease in the blood oxygen levels in emphysema?

Decrease in alveolar surface area results in less boundary across which oxygen can be absorbed into the blood.


Levels of oxygen and carbon dioxide in the blood trigger the respiratory center?

Primarily it is the cabon dioxide levels that trigger respiratory drive, however in some disease states such as COPD increased oxygen levels can decrease respiratory drive.


How does increase of CO2 levels affect photosynthesis?

Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.
