Epithelial Tissues

Front 1

Simple squamous epithelial - structure

Back 1

Single layer of thin, flattened cells.

Front 2

Simple squamous epithelial - function/location

Back 2

Gas exchange in the lungs.
Lines blood and lymphs vessels and various body cavities.

Front 3

Simple cuboidal epithelial - structure

Back 3

Single layer of of cube-shaped cells

Front 4

Simple cuboidal epithelial - function/location

Back 4

Covers ovaries.
Carries on secretion and absorption in the linings of kidneys tubules and lines ducts of certain glands.

Front 5

Simple columnar epithelial - structure

Back 5

Composed of elongated cells with nuclei near the basement membrane.

Front 6

Simple columnar epithelial - function/location

Back 6

Lines the uterus, stomach and small intestines.

Specialized in absorption

Absorbing cells often have microvilli (greater surface area).

Has goblet cells that secrete mucus.

Front 7

Pseudo-stratified columnar epithelium
Structure

Back 7

Nuclei located at two or more levels to give impression of layered.

Front 8

Pseudo-stratified columnar epithelium
Function/location

Back 8

Has cilia which move mucus over the surface.

Goblet cells ( mucus secretion)

Lines passageways of the respiratory system.

Trap dust and microorganisms.

Front 9

Stratified squamous epithelium
Structure

Back 9

Composed of many layer of cells.

Front 10

Stratified squamous epithelium
Function/location

Back 10

Protects underlying cells.

accumulate keratin which hardens the skin.

Forms the outer layer the epidermis and lines the oral cavity, esophagus, vagina and anal canal.

Front 11

Stratified cuboidal epithelium
Structure

Back 11

Two or three layers of cube-shaped cells

Front 12

Stratified cuboidal epithelium
Function/location

Back 12

Protects.

Lines the larger ducts of the mammary glads, sweat glands, and pancreas.

Lines parts of male and female production systems.

Front 13

Stratified columnar epithelium
Structure

Back 13

Top layer = elongated cells
Bottom layer = cube-shaped cells.

Front 14

Stratified columnar epithelium
Function/location

Back 14

Protects and secretes.

In the male urethra and ductus deferens (sædleder) and parts of the pharynx.

Front 15

Transitional epithelium - structure

Back 15

Specialized to response to increased tension.

Front 16

Transitional epithelium
Function/location

Back 16

Inner lining of urinary bladder and linings of ureters (the duct by which urine passes from the kidney to the bladder or cloaca)

Part of the urethra.

Front 17

Glandular epithelium

Back 17

composed of cells that are specialized to secrete substances.

Salivary glands, sweat glands and endocrine glands.

Front 18

Exocrine glands

Back 18

Glands that secrete their products into ducts that open into open surfaces.
Ex. Skin and lines of digestive tracts

Front 19

Endocrine glands

Back 19

Glands that secrete their products into tissue fluids or blood.

Front 20

Exocrine - merocrine glands

Back 20

Secrete fluids without loss of cytoplasm.

Serous cells secrete watery fluid with high enzyme content.

Mucous cells secrete mucus.

Front 21

Exocrine - aprocrine glands

Back 21

lose portions of their cells during secretion.

Front 22

Exocrine - Holocrine glands

Back 22

release cells filled with secretory products.

Front 23

Serous fluid

Back 23

Watery
High concentration of enzymes.
Lubricates.

Front 24

Mucus

Back 24

Rich in the glycoprotein mucin.

Abundantly secreted by cells in the inner linings of the digestive, respiratory, and reproductive systems.

Cells and goblet cells.
