What Are the Functions of Cuboidal Epithelial Cells in the Kidneys?
The kidneys are essential organs responsible for blood filtration. Each kidney consists of an outer cortex rich in blood vessels and an inner medulla. Both the cortex and the medulla contain millions of nephrons, the functional units of the kidney which work to filter the blood. According to the National Space Biomedical Research Institute, the nephrons filter around 43 gallons of water daily. Each nephron consists of several small tubules, which are lined with cuboidal epithelial cells. The cuboidal cells within the tubules perform a range of functions in filtering the blood.
