kuutioepiteliin

Kuutioepiteliin is a type of epithelial tissue characterized by cells that are roughly cube-shaped. Each cell has a nucleus that is typically centrally located and spherical. This shape allows for a greater volume of cytoplasm compared to squamous epithelium, which can facilitate more metabolic activity and secretion. Kuutioepiteliin is found in various locations within the body where absorption, secretion, and protection are important functions.

Examples of kuutioepiteliin include the lining of kidney tubules, where it plays a crucial role in reabsorption and secretion of substances. It also forms the secretory portions of many glands, such as salivary glands and thyroid follicles, contributing to the production and release of hormones and other substances. In some ducts, such as those of the pancreas and liver, kuutioepiteliin is also present, aiding in the transport and modification of secretions. Its structure provides a balance between surface area for transport and cellular capacity for metabolic processes.
