major types of tissue epithelial, connective, muscular, nervous functions of epithelial tissue protection, secretion, , absorption, filtration, excretion, senses simple one layer squamous flat cells stratified multiple layers cuboidal cube shaped columnar column shaped simple squamous shape single layer of flat cells simple squamous function diffusion and filtration simple squamous location found in air sac of the lungs simple cuboidal shape single layer of cube shaped cells simple cuboidal function secretion and absorption simple cubiodal location kidney tubules, surface of ovaries simple columnar shape single layer of long cells, have goblet cells and microvilli simple columnar function secretion and absorption simple columnar location digestive tract and uterus goblet cells secrete mucus microvilli projections that increase the cell's surface area stratified squamous shape several layers, flat stratified squamous function protection stratified squamous location lines body cavities; skin and mouth what happens when the dermis pulls away from epidermis blisters form collagen and elastin connective tissue pseudostratified columnar shape single layer with nuclei at various levels, can have goblet cells and cilia pseudostratified columnar function secretion and cilia-aided movement pseudostratified columnar location linings of respiratory passages, tubes of reproductive system transitional epithelium shape thick, layered cuboidal cells transitional epithelium function stretchable tissue, forms barrier to block diffusion transitional epithelium location urinary bladder glandular epithelium cells that are specialized to produce and secrete substances, makes up the body's glands connective tissue most abundant tissue in your body, binds structures together connective tissue function provides support, prtoection, framework, fills space, stores fat, produces blood cells, fights infection connective tissue composed of scattered cells within a matrix, a ground substance and fibers common types of connective tissue cells mast cells, macrophages, fibroblasts main types of fibers collagenous and elastic collagenous fibers strong, flexible, not very elastic, found in bones, ligaments elastic fibers not as strong, very elastic, found in ears, vocal areolar tissue (loose connective tissue) binds skin to underlying organs, forms thin membranes throughout body adipose tissue (fat) protective cushion, insulation to preserve body heat, stores energy fibrous connective tissue thick collagenous fibers and fine network of elastic fibers
