Better known for their ability to process waste, the kidneys are responsible for the secretion of four different hormones: rennin, calcitriol, erythropoietin and thrombopoietin
These chemicals released by the kidneys affect a wide range of bodily processes dealing with the circulatory and skeletal systems.
Understanding the endocrine functions of the kidneys is necessary to understand the full impact the kidneys have on the body.
Rennin is a proteolytic enzyme responsible for regulating arterial wall size to ensure proper blood pressure.
When blood pressure gets too low, the kidneys secrete rennin into …show more content…
if the kidneys become diseased and fail to produce enough EPO, the marrow makes insufficient blood cells, resulting in anemia.
Recombinant EPO can be used as a treatment for those suffering from anemia, a deficiency of red blood cells.
Calcitriol, also known as vitamin D3, improves the body's ability to absorb calcium.
To produce calcitriol, vitamin D must be introduced into the body, either through a chemical reaction between the skin and sunlight creating calciferol, or dietary vitamin D that has been digested.
Vitamin D in the body ends up being converted into calcitriol by the kidneys. Calcitriol travels to the intestines, where it enhances the body's absorption of calcium, improving skeletal health.
When kidney function stops, the body is unable to absorb calcium from food and instead starts to remove it from the bones.
Thrombopoietin, or TPO, increases the body's ability to heal itself by stimulating the production of
