1

Kinds of squamous epithelia

1.Simples squamous
2.Mesothelium
3.Endothelium

2

Squamous epithelia in charge of absorption and diffusion

Simple squamous

3

Squamous epithelia that lines body cavities

Mesothelium

4

Squamous epithelia that lines heart and blood vessels

Endothelium

5

-Protects against attacks
-Keratin protein adds strength and water resistance
-Keratinized or non-keratinized

Stratified squamous epithelium

6

Kinds of cuboidal epithelia

Simple cuboidal epithelium
Stratified cuboidal epithelium

7

Cuboidal epithelim in charge of secretion and absorption

Simple cuboidal epithelium

8

Cuboidal epithelium in charge of sweat ducts and mammary ducts

Stratified cuboidal epithelia

9

Locations of simple squamous epithelium

Mesothelia lining pleural, pericardial, and peritoneal cavities;
endothelia lining heart and blood vessels;
portions of kidney tubules (thin sections of nephron loops);
inner lining of cornea; alveoli of lungs

10

Functions of simple squamous epithelium

reduces friction, controls vessel permeability; performs absorption and secretion

11

Stratified squamous epithelium locations

surface of the skin, lining of the mouth, throat, esophagus, rectum, anus, and vagina

12

Functions of stratified squamous epithelium

Provides physical protection against abrasion, pathogens, and chemical attack

13

Locations of simple cuboidal epithelium

glands
ducts
portions of kidney tubules
thyroid gland

14

locations of stratified cuboidal epithelium

lining of some ducts (rare)

15

functions of stratified cuboidal epithelium

protection
secretion
absorption

16

-Tolerates repeated cycles of stretching and recoiling and returns to its previous shape without damage

Transitional epithelium

17

Appearance changes as stretching occurs

Transitional epithelium

18

Situated in regions of the urinary system

Transitional epithelium

19

Transitional epithelium can be found in the ________ ________

urinary bladder
