Document Summary

Tissues: groups of cells similar in structure that preform a common or related function. Four primary tissue types interweave to form the fabric of the body: epithelial tissue (covers, connective tissue (supports, muscle tissue (produces movement, nervous tissue (controls) Epithelial tissue (forms boundaries between different environments, protects, secretes, absorbs, filters) Found: -lining of the digestive tract organs and other hollow organs. There are two forms that occur in the body: 1. covering and lining epithelium (outer layer of skin, lines open cavities of urogenital, digestive, and respiratory systems; covers the walls and organs of the closed ventral body cavity: glandular epithelium (fashions the glands of the body) Functions of various epithelia: protection (mechanical, chemical, and infectious, absorption (gi tract, filtration (kidneys, excretion (kidneys, secretion (glands, sensory reception (taste buds, olfactory membranes) Apical surface (upper free surface exposed to the body exterior or the cavity of an internal organ. Basal lamina (thin supporting sheet) which molecules enter the epithelium.
