I believe the correct answer is they protect the tissue.
<h2>Explanation:</h2><h3>Epithelium tissue:</h3>
The epithelium contains a layer of stacked cells called epithelial cells that are simple and form a tough layer on many surfaces and orifices of the body. They are classified according to their structures i.e. the squamous and stratified epithelium. Squamous epithelial cells line surfaces like the cheeks in the mouth and usually wear away easily in cases of abrasion. Stratified epithelial cells are usually very closely stacked together and are tougher than the squamous epithelial cells. They protect open surfaces like the lips, vagina and the anus where friction is very frequent. The cells can additionally be added with a layer of tough proteins called keratin that cover 100% of the exposed skin, hair and nails. They make the skin waterproof and tough and the cells that have them are usually the stratified epithelial cells e.g. the stratified keratinized epithelial cells.

It is one of the types of animal tissues and is very tough since it is used in support and movement where a lot of mechanics occur. It occurs between tissues i.e. linking muscles to bones and they support and also protect the body. The bone is a type of a densely packed connective tissue that is calcified. It contains the osteoblasts that deposit into the bone, the osteocytes that maintains the bone and the osteoclasts that resorb the bone. Despite the bone being tough, it can be classified into the compact and spongy bone. Spongy bone is found in articulation points of the bone and cushions the organ such as the thigh during movement such as jumping up and down. The spongy bone can also be found inside the compact bone and is porous allowing nerves and blood vessels to pass into it. The porous holes are eventually filled by the red or yellow bone marrow. The red bone marrow creates blood cells.
