The cells can be different shapes and can be arranged in a single layer or multiple layers depending on where they are in the body and what kind of functions they have. The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of animal body.  Functions Protection: Epithelial tissue protects several aspects of animal body. For example, skin is made up of epithelial tissue and protects the tissues deeper in animal body, such as blood vessels, muscle and internal organs. Secretion: Epithelial tissue in glands can secrete enzymes, hormones and fluids. Absorption: The epithelial lining of internal organs, such as the internal epithelial lining of intestines absorbs nutrients from the animal feed in gut. Excretion: Excretion is the removal of waste from animal body. The epithelial tissue in the kidneys excrete waste, and the epithelial tissue in the sweat glands excrete sweat. Filtration: The epithelium of the respiratory tract filters out dirt and particles and cleans the air that you breathe in. Epithelial tissue in the kidneys filters the blood. Connective Tissues Connective tissues is made up of connective cells. Functions: - Bind structures together (form a framework) - Support for organs. - Storage fat. - Transport substances. - Protect against disease. - Help repair tissue damage. Connective tissue cells are able to reproduce but not as rapidly as epithelial cells. FUNCTIONS: Cushions and defense against pathogens. FUNCTIONS: Insulation (Reduce heat loss). Store energy. FUNCTIONS: Reduce friction between muscle. Muscle Tissues Nervous Tissues Wrap up Questions 21  End of Lab #1 THANK YOU www.hu.edu.eg
