Document Summary

Tissue: groups of structurally similar cells that perform common/ related function. Muscle tissue : contracts to cause movement. Connective tissue: supports, protects, binds other tissues together. Histology : study of tissues (on a microscope level) Functions: protection, absorption: microvilli involve, filtration, excretion : excrete waste products from body and reabsorb needed materials from the urine, secretion : produce enzymes and hormones, sensory reception. Apical surface is exposed to the environment (celia and micro) Basal surface is made out of glycoproteins and collagen. Basal lamina acts as a lter and support: specialized contacts. Tight junctions & desmosomes: supported by connective tissue. Reticular connective tissue: avascular (a in front of anything means without/ without blood supply) Base layer gives the epithelial tissue nutrients which allows them to undergo mitosis. A single layer of cell of differing heights. Eg : respiratory tract where cilia and mucus secret are local specialization. Lines the bladder, an organ that has to ll.
