Flashcards in Epithelial Tissue Deck (16):
1

Epithelia

Covers exposed surfaces and line internal cavities and passageways

2

Glands

Organized groups of cells or organs that include epithelial cells that synthesize substances for secretion

3

Exocrine glands

Glands that secrete onto external surfaces or into internal passageways(ducts) that connect to the exterior

4

Endocrine glands

Glands that secrete hormones or their precursors that enter the bloodstream for distribution to target tissues

5

Microvilli

Typical associated with epithelial cells that line the passageways of the digestive and urinary tracts

6

Motile cilia

Typically associated with epithelial cells that line the passageways respiratory and reproductive tracts

7

Junctional complexes

Provide support and connects cells to make sure outside substances do not penetrate deeper tissue

8

Simple epithelia

Single layer of cells

9

Stratified epithelia

Found in areas that need more protection from outside sources so there are many layers of cells

10

Simple squamous epithelia

Flat layer of single cells

Lungs for gas exchange
Lining in body cavities
Inner surface of heart and blood vessels

11

Simple cuboidal epithelia

Single layer of cubed cells

Kidney tubules
Thyroid follicles

12

Simple columnar epithelia

Single layer of column like cells

Small intestine
Gall bladder
Uterine tubes

13

Stratified squamous epithelia

Many layers of flat cells

Skin, rectum, lining of mouth, vagina

14

Stratified cuboidal epithelia

Many layers of cubed shaped cells

Sweat gland ducts
Mammary gland ducts

15

Stratified columnar epithelia

Many layers of column like cells

Pancreatic ducts
Salivary ducts

16

How to epithelia get nutrients

They are avascular(no blood cells associated) and they get their nutrients through diffusion or absorption across either the apical, exposed, or basal attached surfaces
