This type of tissue covers most exposed areas of the body and lines the body cavities such as blood and lymph vessels, the digestive tract, and glands. These cells function in:
Protection - they form a barrier that is special for their need (like keeping in liquids or allowing the passage of certain materials). Skin cells protect against foreign invasion and permit homeostasis (keeping the internal environment at a certain desired level). This includes keeping certain substances in their proper place in the body, such as blood in vessels and gastric juice in the digestion system.
Structure / support - they line cavities keeping everything in order.
Secretion - certain cells have the task of secretion, these are found scattered in the appropriate epithelial layers (often times in ducts which are in glands).
The tissues of animals are classified into four different types. They include the epithelial tissue, connective tissue, muscle tissue and neural tissues.
Muscle tissue Connective tissue Nervous tissue Epithelial tissue
Covering surfaces
Epithilial Tissue Lines animal's body Cavity, they can be further subdivided into different types of Epithelial Tissue, depending on what they line
OMG can you only find 4? And you need 5! That is the same with me stuck :S
How is the function of nerve tissue different from that of epithelial tissue?

The pancreas is an organ. It is one of the unique organs that have both endocrine and exocrine functions.
Epithelial, Nervous, and Muscular tissue.
epithelial tissue
Epithelial tissue
the general functions are to protect the inner body veins and organs
epithelial tissue, connective tissue
Epithelial Tissue- this tissue covers any bodily surface including organs, body cavities, and glands. There are subcategories of Epithelial Tissue, which are Squamous (pavement) , Simple Columnar, Simple Cuboidal, Glandular, Stratified, and Ciliated Columnar. The main functions of epithelial tissue are sensation, absorption, protection, cleaning, reduction of friction, excretion, diffusion, and secretion. Connective Tissue- this tissue forms blood, cartilage, and bone. It is classified into dense connective, loose connective, reticular, elastic, and adipose. Muscle- contractile tissue that causes movement in an organism as well as internal functions. The three types of muscle tissue are skeletal, smooth, and cardiac. Nervous Tissue- this tissue is responsible for sending and receiving messages from muscle tissue to the brain. Nervous tissue is composed of neurons.
Epithelial Tissue
Epithelial tissue is innervated.
