Numerous physiological processes depend on the simple cuboidal epithelium, which is distinguished by its single layer of cube-shaped cells with central nuclei. Its presence in glandular ducts, such as those of the pancreas and salivary glands, where it releases enzymes and other products, is an example of its primary function in secretion. It also makes absorption easier, as seen by the kidney tubules, which actively move chemicals from the blood to the urine. Its function in the synthesis and storage of hormones is made apparent by its presence in thyroid gland cells. Additionally, it provides some protection by lining organs such as the surface of the ovary. Simple cuboidal epithelium, for example, lines the renal tubules in the kidney section of frogs and aids in the excretory processes of the kidney. These various roles emphasize how crucial simple cuboidal epithelium is to preserving organ function and tissue homeostasis.
