Quiz 2 Tissues Flashcards
What is the shape of simple squamous epithelium?
flat and irregular
How many cell layers are there in simple squamous epithelium?
1 layer
Alveoli (air sacs) in the lungs_____
help with the exchange of oxygen and carbon dioxide between the blood and inhaled air.
What is the shape of cells in simple cuboidal epithelium?
Cube like. as tall as they are wide.
How many cell layers are there in simple cuboidal epithelium?
1 layer
Lining lumen of stomach and intestines_____
function primary for absorption and secretion. forms the walls of kidney tubules where it participates in the reapsoprtion of nutrients, ions and water that are filtered out of the blood plasma
What is the shape of pseodostratisfied ciliated columnar epithelium ?
“Multiple layers” looking like columns with cilia on top
How many cell layers are there in pseodstratisfied ciliated columnar epithelium?
1 layer
What membrane specialization on the free surface do you see in pseudostratisfied ciliated columnar epithelium?
Cilia.
why is pseudostratsfied ciliated columnar epithelium called pseodostratisfied?
At first glance, it looks like there are multiple layers, but there is just one layer.
Bronchi and trachea ____
have pseodostratisfied columnar epithelium that have cilia that help propel dust particles and foreign materials away from the lungs and toward the nose and mouth.
What is the shape of stratisfied squamous epithelium?
basal layer is cuboidal and apical layer is flattened
What is the number of cell layers in stratified squamous epithelium?
Multiple layers
Lining of mouth, anus, and esophagus_____
for protection against abrasion and friction.
Shape of transitional epithelium?
cells on basal surface are typically columnar
How many layers are there in the transitional epithelium?
multiple layers
Why is it important to have transitional epithelium in places where stretching occurs? such as the bladder and ureters.
the bladder and ureters can stretch to accommodate the storage or passage of urine without tearing.

multiple
Defining characteristic of skeletal muscle
looks like salmon
