detoxifies drugs, makes fats (lipid synthesis), reduces alcohol and turns it into fat, so excessive drinking turns your whole liver into fat

• in gut and kidney (absorptive areas)
• little and stubby- hard to see on the surface (too packed together and all the same height)

cilia

have long molecular motors to beat and push things along
• move mucus along respiratory tract and out of the trachea and bronchi
• female reproductive tract to move the egg through the filopian tubes

epithelium

Covers surfaces, lines cavities, forms glands.

Cells and tissue show polarity: top (apical surface- might have surface specializations like cilia or microvilli) differs from bottom (basal surface- rests on a basement membrane).

This tissue shows the most rapid turnover of all tissues, therefore most prone to cancer.

Epithelia are avascular (lack blood vessels).

types of cell junctions

 tight junctions form a seal between cells- cells lining the stomach
• plasma membranes from opposing cells actually seal the cells together to prevent leakage

 desmosomes- mechanical function, helps cells stick together, kinda like Velcro (skin, heart- under a lot of mechanical stress)

simple epithelia

 simple squamous epithelium- single layer of cells resting on a basement membrane
• in lungs- need a really thin layer for gas exchange

• tall, column shaped, lined up with each other
