Epithelial Cells
avascular
no blood system
squamous
flat cells- transportation and absorption
cuboidal
3d shape- absorption, good for cells that have organelles that make chemicals e.g., stomach lining secretion
columnar
longer- cushion underlying tissue
simple epithelium
single layer
stratified
multiple layers
pseudo-stratisfied
usually one layer- cells are different shapes and sizes. nucleui at different levels-> looks multi-layered but isnt
transitional
many layers, cells are usually specialised. allows tissue to expand and contract
ciliated columnar
clearing and moving substances
glandular
produce/release secretions, cuboidal shape, contain goblet cells->synthesis/secretion of chemicals
fallopian tubes
ciliated columnar
respiratory tract
ciliated columnar, pseudo stratisfied
cervix, intestinal lining, glands
glandular
bladder
transitional
