Epithelial Tissue Activity
Simple Squamous
• Description
– Single layer of thin, flattened cells that fit tightly
together.
• Function
– Allows diffusion and filtration (ex: oxygen and carbon
dioxide are exchanged)
• Location
–
–
–
–
Lines the air sacs (alveoli) of the lungs
Forms walls of capillaries
Line the blood and lymph vessels
Covers membranes that line body cavities.
Simple Cuboidal
• Description
– Single layer of cubed-shaped cells.
• Function
– Secretion and reabsorption in the kidneys
– secretion from glands.
• Location
–
–
–
–
Lines the follicles of the thyroid gland
Covers the ovaries
Lines the kidney’s tubules
lines the ducts of certain glands (salivary, pancreas,
and liver).
Simple Columnar
• Description
– Single layer of elongated cells.
• Function
– Ciliated and helps move an egg through the uterine
tube.
– Non-ciliated protects underlying tissues, secretes
digestive fluids, and absorbs nutrients from digested
food.
• Location
– Ciliated is found in the uterine tube.
– Non-ciliated lines the uterus and portions of the
digestive track (stomach and the intestines).
Pseudostratified
• Description
– Single layer of cells where the columns are at
different heights.
• Function
– Sticky and trap dust and microorganisms. Cilia
move mucus and captured particles out of airways.
• Location
– Lines the passageways of the respiratory system.
Stratified Squamous
• Description
– Many layers of flattened cells.
• Function
– Prevents water and other substances from escaping
underlying tissues and blocks chemicals and
microorganisms from entering.
• Location
– Outermost layer of skin.
– Lines oral cavity, esophagus, vagina, and anal cavity.
Transitional
• Description
– Many layers of cubed-shaped and elongated cells.
• Function
– Forms a barrier that helps prevent the contents of the
urinary tract from diffusing back into the internal
environment.
• Location
– Inner lining of the urinary bladder, lines ureters, and
part of the urethra.
