Document Summary

Classification of cells is based on apical surface, everywhere we have epithelial tissue we have connective tissue. Simple squamous are the thinnest cells when it comes to epithelia: central nuclei and sparse cytoplasm, allows passage of materials by diffusion and filtration incites where protection is not important; secretes lubricating substances in serose. Simple cuboidal: good for secretion and absorption. Simple columnar: good for secretion and absorption, pseudostratified ciliated columnar epithelium, good for secretion of mucus. Stratified squamous epithelium: protects underlying tissues in areas subjected to abrasion. Stratified columnar epithelium: good for protection and secretion, transitional epithelium, stretches readily and permits dimension of urinary organ by contained urine. Lines the uterus, bladder, and part of the urethra: resembles both stratified squamous and stratified cuboidal, glandular tissue - epithelial, exocrine. Into ducts: mucous, sweat, oil, saliva, gi, endocrine. Into blood circulation (no ducts: hormones, cell junctions - epithelial, desmosomes, anchor cells together.
