Basement Membrane

The Basement Membrane is a thin and dense, sheet-like structure made of several proteins and extracellular matrix proteins that forms a barrier between different layers of tissue and organs in the body. Its main function is to provide mechanical and metabolic support, while also acting as a selective barrier that helps regulate the flow of certain substances into and out of the tissue. The Basement Membrane also acts as a filter, allowing the entry of small molecules and nutrients, while preventing the entry of larger molecules. It is an essential component of the body's defense system, helping to prevent the spread of infections, and can be found in a variety of organs, including the stomach, the lungs, and the colon. Furthermore, in the skin, it helps to maintain structure and integrity, and plays an important role in wound healing.
