What is the function of erythropoietin in response to hypoxia?
Wiki User
∙ 13y ago
Erythropoietin triggers more red blood cells to be produced in the bone marrow. Red blood cells carry oxygen throughout the body, therefore if there are more red blood cells than more oxygen can be exchanged throughout the body decreasing lack of oxygen (hypoxia). So in hypoxia the kidneys produce and increased amount of erythropoietin.

What is secreted in response to hypoxia?
Erythropoietin is secreted in response to hypoxia. It produces a negative feedback loop that raises the oxygen concentration of the blood. Also called EPO, erythropoietin, is a glycoprotein hormone that controls red blood cell production.
What is secreted in response to hypoxia and produces a negative feedback loop that raises the oxygen concentration of the blood?
erythropoietin
Which of the stimuli makes the kidneys secrete erythropoietin?
Hypoxia
Hypoxia will stimulate and increase in the release of what which will stimulate erythropoesis?
erythropoietin
Tissue hypoxia stimulates kidney cells to release?
erythropoietin
Hypoxia stimulates kidney cells to release?
Hypoxia stimulates kidney cells to release erythropoietin, which is a hormone that regulates red blood cell production. Hypoxia is a condition where a part of the body or brain is not getting sufficient oxygen. When this condition occurs, there is an increase red blood cell production.
Erthropoitein which stimulates red blood cell production is produced by the?
Erythropoietin, a hormone secreted by the kidney, stimulates the production of red blood cells. Almost all of the erythropoietin within the circulation is derived from the kidneys. Hypoxia is one of the main stimuli that induces erythropoietin secretion from the kidneys. In severe kidney disease, a decrease in erythropoietin production results in severe anemia.
What is tissue hypoxia?
Tissue hypoxia (oxygen deficiency) occurs when the blood vessels in the hands, feet, and other extremities narrow in response to cold
What is iflammation of the bone marrow?
A major factor in the anemia of infection, inflammation, and malignancy is a relative failure of the bone marrow to increase erythropoiesis in response to a shortened red cell survival. The possible causes for this diminished marrow response are: (a) a reduced production of erythropoietin, or, (b) impaired bone marrow response to erythropoietin. In this report studies were performed on 6 normals, 13 patients with anemia from infection or inflammation, and 18 patients with anemia caused by advanced malignancy. Serum erythropoietin activity was measured using the posthypoxic, policymaker mouse assay. Assessment of bone marrow response to erythropoietin was made by measuring 59Fe-heme synthesis in bone marrow suspensions cultured for 3 days with and without the addition of erythropoietin. The results showed that marrow heme synthesis was increased in erythropoietin-treated cultures as compared with saline control cultures by 66±8% (mean ±SE) in normals, 101±10% in patients with infection or inflammation, and 31±5% in malignancy. Serum erythropoietin levels were consistently diminished relative to expected levels for the degree of anemia in the infection-inflammatory group, but not in malignancy. In these patients, plasma inhibitors to the biological activity of erythropoietin were not detected in Vito. These studies suggest that another factor to consider in the anemia of malignancy is a decreased bone marrow response to erythropoietin. In the anemia of infection-inflammation, marrow response to erythropoietin is normal, but serum levels of erythropoietin are decreased relative to the degree of anemia.
What is renal hormones?
The kidneys secrete a variety of hormones, including erythropoietin, and the enzyme renin. Erythropoietin is released in response to hypoxia (low levels of oxygen at tissue level) in the renal circulation. It stimulates erythropoiesis (production of red blood cells) in the bone marrow. Calcitriol, the activated form of vitamin D, promotes intestinal absorption of calcium and the renal reabsorption of phosphate. Part of the renin-angiotensin-aldosterone system, renin is an enzyme involved in the regulation of aldesterone levels.
What is the stimulus for erythropoetin production and release?
Erythropoietin is a hormone that is released by the kidneys during periods of low blood oxygenation in order to increase the number of erythrocytes (red blood cells) in the serum.
What hormones stimulates proliferation of red blood cells in red bone marrow?
Erythropoietin, a hormone secreted by the kidney, stimulates the production of red blood cells. Almost all of the erythropoietin within the circulation is derived from the kidneys. Hypoxia is one of the main stimuli that induces erythropoietin secretion from the kidneys. In severe kidney disease, a decrease in erythropoietin production results in severe anemia.
