Tissues- Epithelial Flashcards
4 types of tissues
- Epithelial
- Connective
- Muscle
- Nerve
8 main types of epithelial tissues
- Simple squamous
- Simple cuboidal
- Simple columnar
- Stratified squamous
- Stratified cuboidal
- Stratified columnar
- Transitional
- Pseudostratified
What are the locations of simple squamous epithelium?
- Mesothelia lining ventral body cavities
- Endothelia lining heart and blood vessels
- Portions of kidney tubules
- Inner lining of cornea
- Alveoli of lungs
Functions of simple squamous epithelium?
- Reduces friction
- Controls vessel permeability
- Performs absorption and secretion
Locations of simple cuboidal epithelium?
- Glands
- Ducts
- Portions of kidney tubules
- Thyroid gland
Functions of simple cuboidal epithelium?
- Limited protection
- Secretion and absorption
Locations of simple columnar epithelium?
- Lining of stomach
- Lining of intestines
- Lining of gallbladder
- Lining of uterine tubes
- Collecting ducts of kidneys
Functions of simple columnar epithelium
- Protection
- Secretion & absorption
Locations of stratified squamous epithelium?
- Surface of most skin
- Lining of mouth
- Lining of throat
- Lining of esophagus
- Lining of rectum
- Lining of anus
- Lining of vagina
Functions of stratified squamous epithelium?
-Provides physical protection against abrasion, pathogens and chemical attack.
Locations of stratified cuboidal epithelium?
Lining of some ducts
Functions of stratified cuboidal epithelium?
- Protection
- Secretion & absorption
Locations of stratified columnar epithelium?
Small areas of the
- Pharynx
- Epiglottis
- Anus
- Mammary gland
- Salivary gland ducts
- Urethra
Function of the stratified columnar epithelium
Protection
Locations of transitional epithelium
- Urinary bladder
- Renal pelvis
- Ureters
Functions of transitional epithelium
Permits expansion and recoil after stretching.
Locations of pseudostratified ciliated columnar epithelium?
Lining of
- Nasal cavity
- Trachea
- Bronchi
- Portions of male reproductive tract
Functions of pseudostratified ciliated columnar epithelium?
Protection & secretion
What are the two types of glands?
- Exocrine glands
- Endocrine glands
Glands that do deliver products to targets through ducts. (have ducts)
Exocrine glands
Glands that do not deliver products to targets through ducts (ductless glands)
Endocrine glands
Gland with watery secretions (may possess enzymes)
Serous glands
Glad that secretes mucus (thicker and productive)
Mucous glands
Gland that secretes both serous and mucous secretions.
Mixed exocrine glands
