Question

what is the function of cuboidal epithelium​

Answer 1

Answer:

The important functions of the simple cuboidal epithelium are secretion and absorption. This epithelial type is found in the small collecting ducts of the kidneys, pancreas, and salivary glands.

Answer 2

Owing to the shape of the cells, the primary functions of the simple cuboidal epithelium are secretion, absorption, and covering.

1. Covering/ Protection

• They function as a covering for several organs providing protection against damage and other chemicals.
• They also cover the outer lining of the seminiferous tubules in the testes.
• The cuboidal epithelium in other parts like the lining of the ducts in the respiratory tract provides a lining and covers the internal structure, providing protection against mechanical wear and tear.

2. Secretion

• They also perform the function of producing biologically active fluids like the cerebrospinal fluid and the hormones.
• The cuboidal epithelium in the thyroid glands is an example of this where the cells line the thyroid follicles responsible for the production of thyroid hormone.
• The ependyma in the brain is formed by a single layer of the cuboidal cells that produce the cerebrospinal fluid.

3. Absorption

• Depending on the location, the cells of the simple cuboidal epithelium may be involved in either active or passive transport of materials.
• The proximal convoluted tubules and distal convoluted tubules in the kidneys, lined with the simple cuboidal epithelium remove the excess water and other waste materials and also maintain the pH and ion balance of the body.
• The cilia present in the apical surface of the cells of the cuboidal epithelium in the kidneys that aid the absorptive function.
