What is a simple block of epithelium?
Simple block epithelium is a cube -shaped cell that line different surfaces and cavities all over the body, including eyes and thyroid gland. These cells perform effects such as secretion and absorption, and also provide protection for different points on the body. The simple block epithelium is composed of a single layer of cubic cells connected to the basal membrane and is simple in its appearance compared to stratified epithelial tissues. In addition to eye lining and thyroid, a simple block epithelium also surrounds the renal tube and ovaries, which provides protection and secretion function. The basement membrane is a thin sheet of fibers, which occupies under the space of epithelial cells and acts as an anchor. The simple block epithelium is very simple and simple in its appearance, hence the name, and is easily recognizable under the microscope. The great cell structure in epithelial tissue is somewhat related to its function because it provides a passage that helps to secrete and absorb substances.
The two main functions of this epithelial tissue are secretion and absorption and tissue in many parts of the body in which it is essential for these events. For example, the eyes secrete water through tear channels, and the salivary glands perform the same process as the result of the function of the block epithelium. Spankreas excludes insulin to help reduce blood sugar through the exocrine gland by the process of simple bloody epithelium and the kidney contains an absorbent lining that helps to pass nutrients and other compounds. The ovaries in women also contain a simple cure epithelium of tissue, as it is constantly excluded by hormones such as estrogen and progesterone, which help in secondary sexual properties and natural cyclical changes in women.
6 A good way to determine which type of simple epithelial tissue is monitored under an electron microscope is to determine whether the cells contain a core. When this material is given to students who learn different types of epithelial tissues, the question is asked where toA simple block epithelium is scraped. The best answers would be the kidneys and ovaries, as these organs constantly exclude and absorb substances daily.
