Document Summary

Extracellular matrix is a complex network of secreted macromolecules. This matrix that we see around cells are generally product of those cells. Cartilage cells will secrete a cartilage type matrix. They secrete a matrix that they will live in. It is like building houses for you to live in. That matrix and that cell type will make that tissue type. The matrix has a lot of important functions. There are a lot of tissue that needs the external support. Muscles are always contracting so the matrix needs to hold them together. Skin needs matrix to keep those skin cells together. The matrix are there to organize an environment for cells to move and interact. The matrix provides a ladder or stairway for cells to interact. It also prevents the cells from getting away from it"s tissue type. The matrix organizes events for tissues to work together.
