Epithelial Tissue

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)
