(25 cards)
Epithelial tissue covers . . .
All faces of the body surfaces and is the major tissue of glands
Epithelium is anchored to connective tissue by a
Basement tissue
The free surface of a epithelia tissue is called
Apical
Most apical surfaces have
Microvilli (absorption)
Epithelium is Innervated but avascular meaning?
there is no blood supply , comes from underlying tissue
Epithelium has a____ high ability as long as it receives adequate nutrition
regenerative
the functions of epithelium include:
protection, absorption, filtration, excretion, secretion, and sensory reception
simple squamous epithelium
this tissue is a single layer of thin, flatten cells
substances can pass through simple squamous epithelium relatively easily, because of this you can find it . . .
lining blood vessels. and air sacs of the lungs
endothelium
provides a silck lining to lymphatic vessels, blood vessels, the heart
Mesothelium
the tissue found in serous membranes that line and cover the ventral body cavity
simple cuboidal epithelium
a single layer of cube shaped cells
simple cuboidal carries on . . .
secretion and absorption in the kidneys and various glads, ex: salivary glands.
simple columnar epithelium is . . .
made of elongated cells whose nuclei are located near the basement membrane.
simple columnar epithelium lines the ___ and ___- where is functions in protection, secretion and absorption
uterus and digestive tract

Pseudostatified columnar epithelium
the tissues appears to be stratified (layered) but it’s not
Pseudostatified columnar epithelium cells have ___ that function to __

many time Pseudostatified columnar epithelium contain . .
goblet cells that secrete mucas
Pseudostatified columnar epithelium lines various tubes of the . . .
respitpry and reproductive systems
Startified squamous epithelium
this tissue has many cells
Startified squamous epithelium thickness protects . .
underlying cells from harmful environmental effects
Startified squamous epithelium can be found covering . .
the skin and lignin the inside of the mouth
Startified squamous epithelium canbe
