widespread throughout the body
lines body surfaces anchored to the basement membrane made up of tightly packed cells containing little intercellular material generally lack blood vessels are replaced frequently |
|
|
Simple Squamous Epithelium
|
Made up of a simple layer of thin, flattened cells; well suited for diffusion, functions in the exchange of gasses in the lungs
lines the blood and lymph vessels as well as body cavities |
|
|
simple cuboidal epithelium
|
a single layer of cube-shaped cells
centrally located nuclei functions in SECRETION and ABSORPTION in the kidneys and SECRETION in the glands |

Simple Columnar Epithelium
|
a row of elongated cells whose nuclei are all located in the basement membrane
may be ciliated lines the uterus, stomach, and intestines and protects the underlying tissues, secretes digestive fluids and absorbs nutrients |
|
|
Ciliated Columnar Epithelium
|
appear layered, but are not
varying positions of the nuclei cilia or mucus is common created goblet cells lines respiratory tubes |
|
|
Stratified Squamous Epithelium
|
Made up of layers of flattened cells
protect underlying layers makes up the outer layer of the skin lines the mouth, throat, vagina, and anal canal |
|
|
Glandular Epithelium
|
classified by the way they secrete their products
|
|
|
Merocrine
|
release fluid products through exocytosis in the pancreas
groupsed as serous (watery fluid) or mucus |
|
|
apocrine
|
glands lose portions of their cell bodies during secretion
like mammary glands |
|
|
halocrine
|
glands release entire cells
sebaceous glands like hair, skin, nails, etc. |
