How are cells, tissues, organs and organ systems linked?
There’s a very simple way to look at it. Organ systems rely on organs which are made from tissue that’s made from cells. There are different kinds of tissue that perform different functions. Take the Epithelial Tissue – The cells of epithelial tissue pack tightly together and form continuous sheets that serve as linings in different parts of the body. Epithelial tissue serve as membranes lining organs and helping to keep the body’s organs separate, in place and protected. Some examples of epithelial tissue are the outer layer of the skin, the inside of the mouth and stomach, and the tissue surrounding the body’s organs. These are made up of Fast growing cells which die and replace quicker in parts of the body that have busy “traffic”such as the mouth. Tissue protects our organs from vibrations and knocks, even cuts or tearing. Cells are all the millions of fibers that link tissue together, so cells perform another function as well -they make up the tissue fibers that protect our organs
