air and is dry. The cutaneous membrane is composed of keratinizing stratified squamous epithelium. The second is the mucous membrane‚ which is the tissue used for absorption and secretion‚ protective lubricating mucus in the repertory and digestive system. This membrane lines the hollow organs‚ such as the throat‚ urinary or digestive tracts. The mucous membrane can be made up of simple columnar epithelium. The last type is the serous membrane. This membrane can line and cover the abdominal cavity

Skin‚ absorbs. Stomach and intestinal lining‚ filters. The kidney‚ secretes. Forming of glands‚ closely attached to each other forming a protective barrier‚ always has one free surface open to outside the body or inside an internal organ‚ has no blood vessels but can soak up nutrients from blood vessels in connective

There are four primary tissue types in the human body - epithelium‚ connective tissue‚ nervous and the muscle tissue. Epithelial tissue- This tissue is specialised to cover the whole part of the body lining of all of the internal and external body surfaces‚ they are packed tightly together to form continuous

referring to the flatness of the cells. They fit jointly‚ rather like crazy paving. Clearly‚ such delicate thin cells cannot offer much protection and their chief function is to allow materials to pass through via diffusion and osmosis. Simple squamous epithelium is found in the walls of; lung alveoli‚ blood capillaries and Bowman’s capsule of nephrons. As their names propose‚ cubiodal cells are cube-shaped‚ with spherical nuclei. They often line ducts and tubes and can allow materials to pass through in

HISTOLOGY: EPITHELIAL TISSUE o Human body composed of 4 basic types of tissue: epithelial‚ connective‚ nervous and muscular o Formed by cells and molecules of the extracellular matrix o Connective tissue: characterized by the abundance of extracellular fluid o Organs can be divided by parenchyma (composed of cells for main function of organ) and stroma ( supporting tissue) o Except in brain and spinal cord stroma made of connective tissue o Epithelial tissue: covering‚ lining protecting surfaces

absent or negligible · Number of cells are large Depending on the structures that correlate with their unique functions‚ epithelial tissues are classified into simple and stratified epithelium. • Simple Epithelium: Cells are arranged in a single layer and does not contain matrix. There are four types of simple epithelium; squamous‚ columnar‚ cuboidal and glandular. · Squamous: Thin and flat tissue and forms a delicate lining. They are arranged closely and jointed by cement material. Example: Lining

I. Stratified Squamous Epithelium (left side) Flat epithelial tissues which are flat and have more than one layer. The Skin for a barrier. Your skin‚ for example‚ is a formidable barrier against many things. Skin is created when the basal cells in skin are dividing by the process of mitosis and‚ as division takes place‚ the cells get pushed upwards. As a result‚ the newer cells tend to stay near the bottom of the epithelial tissue‚ and the older cells get pushed upward and eventually
