Desquamification Friction
________ causing top layer of stratified squamous cells to fall off.
Transitional Epithelium
________- stretch to squamous shape (full) to cuboidal (empty)
Microvilli
________- increases surface area for absorption.
Pathologist
________- studies the diseases of cells and tissues.
Basement Membrane
________- bottom of epithelial tissue that has glycoproteins and reticular fibers.
Cuboidal
Stratified ________- layered, secretes, glands.
Cellularity
________- more cells than matrix.
Melanocytes
________- make and release melanin.
Keratin
________- waterproof protective top layer of skin.
Simple Columnar
________ w /microvilli- absorption of nutrients, intestines.
Tissue
________- group of similar cells that together carry out a specific job.
Melanin
________- skin, eye, and hair pigment.
Avascular
________- no blood vessels.
Epithelium
Stratified ________- more than one layer, classified by top layer.
Simple Cuboidal
________- One layer, secretes, glands.
Exocrine Glands
________- products are carried by a duct to a hollow organ (digestive enzymes) or out of body (sweat)
Squamous
Stratified ________- takes friction, is a barrier, protects from fluid loss /Esophagus, skin, mouth.
Simple Squamous
________- Diffusion, filtration, slick /Lungs, heart, blood vessel, kidneys.
Goblet cells
________- single cell gland that secrete mucus.
Endocrine Glands
________- secretes hormones directly into blood.
Mitotic Cells
________- Cells in the stratified squamous tissue that regenerate (mitosis)
