The kidneys monitor oxygen levels in blood and if they are low then the kidneys release erythropoetin in to the blood stream. Red bone marrow cells have erythropoetin receptors and start to produce erythrocyte's in the bone marrow, then they go into the blood stream. This goes on until leaves are back to normal. Since there are more blood cell there is more oxygen carrying capacity.

What is the relationship between vo2 max and cardiac output?

Cardiac output is the amount of blood that cardiac muscle is pumping out within one minute. it is measured in liters per minute.VO2 maxmeans maximal oxygen consumption, maximal oxygen consumption is the maximum capacity of an individual's body to transport and use oxygen during maximum work. It is measured in milliliters per minute per 1kg of working muscle.Some factor's are affected in this relationship .Oxygen carrying capacity of the blood -- how much oxygen is your blood carrying per unit of blood -- typically expressed in ml of oxygen per 100 ml of blood or per liter of blood.The amount of oxygen blood is carrying is a function of how much hemoglobin you have in your blood and the pressure of oxygen (PO2) in the arteries that are delivering the blood.Each gram of hemoglobin can carry 1.34ml of oxygen, if fully saturated (as it pretty closely is at sea level), so if we have hemoglobin count of 15 this means we can carry about 20 (15X1.34)ml oxygen per 100 ml blood or 200 ml per 1 liter of blood. Since we are only about 97% saturated the numbers become about 19 or 190.Then if we can pump 20 liters per minute (20-liter cardiac output), we can deliver 3800ml oxygen per minute -- 190 per liter X 20 liters. Obviously if we reach a cardiac output of 30 liter per minute then we could deliver 5700ml O2 per minute. Also, if we have less hemoglobin or at altitude where the hemoglobin is not as saturated with oxygen, then we will deliver the same amount of blood but less oxygen.Anyway VO2 max depends on how much oxygen we can deliver (the central factor) and at the exercising muscle, how much of the delivered oxygen can the muscle use per minute to convert fuel into energy.Vo2 max can be defined by Fick equationQ is the cardiac output of the heart, CaO2 is the arterial oxygen content, and CvO2 is the venous oxygen content, from the Fick equation it can be seen that Vo2 max has a linear relationship with cardiac outputVo2 = cardiac output x AVo2 difference....Cardiac output = HR x stroke volumeStroke volume: Determined by size and strength of heart muscle tissue.AVo2 difference = Measures how much oxygen is taken up by the muscles. The difference in arterial vs venues blood oxygen content.Blood comes to the muscles via arteries. Number of capillaries and mitochondria is the main determining factor how much oxygen is taken up by the muscles. Capillaries take the blood deep into the muscle and across more muscle. Oxygen is then "dropped off" at the mitochondria IF it is needed. More mitochondria, more need.The more changeable factor here is the A Vo2 difference


What factors are considered when oxygen therapy is recommended?

The need for supplemental oxygen is determined by inadequate oxygen saturation, indicated in blood gas measurements, pulse oximetry, or clinical observations.


What is the relationship between pH and Dissolved Oxygen?

i dont know i need help with this question as well


Did paul and Barnabus reconcile?

They were brothers in Christ, however that is the extent of their relationship. they were not related by blood.


What is the relationship between thrombosis and atherosclerosis?

The only similarity between these two conditions is that they effect the blood vessels. Thrombosis is the formation of a blood clot and atherosclerosis is hardening of the arteries or blood vessels.

How is oxygen carried vby the body to the cells of the kidneys?

Oxygen is carried by red blood cells in the bloodstream to the kidneys. Hemoglobin, a protein in red blood cells, binds to oxygen in the lungs and releases it to the cells in the kidneys as blood flow through the renal arteries. This process ensures that the cells in the kidneys receive the necessary oxygen for their metabolic functions.


What role do the kidneys play in erythropoiesis?

The kidneys produce erythropoietin, a hormone that stimulates the production of red blood cells in the bone marrow. This hormone signals the bone marrow to increase the production of red blood cells in response to low oxygen levels in the blood.


Why is the renal vein low in oxygen?

The renal vein is low in oxygen because it carries blood that has already been filtered by the kidneys. As the blood flows through the kidneys, waste products are removed and nutrients are reabsorbed, which depletes the oxygen content of the blood.


Does the bladder bring oxygen to the blood?

No, the bladder stores urine that is produced by the kidneys. Oxygen is transported to the blood through the lungs and carried by red blood cells.


What blood vessel carries blood from the heart to the kidneys?

The renal artery delivers blood to the kidneys.


What do kidneys secrete when oxygen levels decrease?

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.


How is blood leaving the left side of the heart different from the blood entering the right side?

The blood leaving the kidneys have most of the waste products removed. The kidneys do use some of the oxygen in the blood, but only a tiny amount, so the outflow is essentially clean arterial blood.


What are function of the renal artery?

The renal artery supplies blood to the renal system, or the kidneys. The renal artery differ with the renal vein in containing the less concentration of co2 and more concentration of urea


Where does blood get rid of carbon dioxide?

No. The red blood cells get oxygen at the lungs, not drop off carbon dioxide.


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?

If blood oxygen levels decrease, the kidneys may not receive enough oxygen to function properly. This can lead to kidney damage and impaired kidney function. In severe cases, it can result in acute kidney injury.


Why do our kidneys have a higher blood flow than the brain?

The kidneys have a higher blood flow than the brain because their main function is to filter blood and remove waste products from the body. This requires a large amount of blood to be processed by the kidneys. In contrast, the brain's main function is not filtration but instead relies on a steady supply of oxygen and nutrients for energy.
