epithelium
Tissues are groups of similar cells that perform a common function. There are four categories of tissues in the human body: epithelial, connective, nervous, and muscle.Epithelial tissue protects your body from moisture loss, bacteria, and internal injury. There are two kinds of epithelial tissues:Covering and lining epithelium covers or lines almost all of your internal and external body surfaces; for example, the outermost layer of your skin and other organs, and the internal surface lining of your lymph vessels and digestive tract.Glandular epithelium secretes hormones or other products such as stomach acid, sweat, saliva, and milk.
All surfaces of the body are composed of epithelial tissue.
Epithelia tissue lines all the body's surfaces and cavities.It is found on the surface of the body (skin) and lines the entire digestive tract, reproduction tract, respiratory track and lungs, excretory system, and endocrine system.Epithelia tissues that line the spaces of the body that are not directly open to the outside of the body such as the lymphatic system, blood system, and endocrine system is called endothelium. (Endothelia is a type of epithelia tissue by definition.)
Undifferentiated mesenchymal tissue
YES.
Epithelial tissue lines all of the body's organs.
Epithelial tissue is a major category of tissue which lines all our body surfaces. It can be classified by a combination of shape (squamous, cuboidal, columnar) and layers (simple, stratified, pseudostratified).
Epithelia are tissues consisting of closely apposed cells without intervening intercellular substances. Epithelia are avascular, but all epithelia "grow" on an underlying layer of vascular connective tissue. The connective tissue and the epithelium are separated by a basement membrane. Epithelium covers all free surfaces of the body. Epithelium also lines the large internal body cavities, where it is termed mesothelium.
Epithelial tissue, which covers the whole body, is made up of closely packed cells arranged in one or more layers. This tissue covers or forms the lining of all internal and external body surfaces.
Covering epithelium is tissue which covers and lines all of the bodies surfaces and cavities inside and out for example the skin.

connective tissue There are four main types of tissue in the human body. The epithelial tissue covers all of the outer body plus lines most of the internal organs. The other tissues found in the body are nerve, connective and muscle.
The membrane of fibrous connective tissue which closely invests all bones except at the articular surfaces.

Differences: 1) Position -- Mucous membranes line cavities that connect with the exterior, including the digestive, respiratory, reproductive, and urinary tracts. Serous membranes line the sealed, internal cavities of the body. There are three such membranes with each consisting of a simple epithelium supported by loose connective tissue: the pleura lines the pleural cavities and covers the lungs the peritoneum lines the peritoneal cavity and covers the surfaces of enclosed organs such as the liver and stomach the pericardium lines the pericardial cavity and covers the heart. 2) Function -- Mucous membranes protect the tracts from mechanical factor, chemical substances, and microorganism invasion. Serous fluid covers the surfaces to minimize friction between opposing surfaces. 3) Types -- Mucous membranes: simple epithelia, stratified squamous epithelium, the transitional epithelium Serous membranes: there are parietal and visceral portions. Parietal lines the outer wall of the internal chamber. The visceral portion covers organs within the body cavity. Similarities: 1) They are kept moist at all times. 2) They are meant to protect http://answers.yahoo.com/question/index?qid=20090702050355AAZKkCd
