Which term refers to the structure that provides support to cells and tissues?

The extracellular matrix (ECM) is a crucial structure that provides support to cells and tissues. It is a complex network composed of proteins, glycoproteins, and carbohydrates that resides outside the cells. The ECM serves multiple purposes, including providing structural support, facilitating cell adhesion, and regulating various cellular functions, such as communication and differentiation. Additionally, the ECM plays a significant role in tissue repair and maintenance.

Support is essential for maintaining the integrity and functionality of tissue architecture, and the ECM ensures that cells are appropriately anchored and can collaborate effectively within the tissue. It also serves as a reservoir for growth factors and signaling molecules that influence cell behavior, further emphasizing its importance in the overall physiology of multicellular organisms.
