Besides oxygen, what other bloodborne material must be provided to the affected tissues in adequate quantities to promote normal wound healing?
nutrients
Diabetics with poor lower limb circulation often have slow-healing pressure ulcers on the bottom of their feet. In speeding up the healing process, surgical removal (debridement) of dead tissue from an ulcerative area would encourage increased.......
granulation tissue formation
Your instructor gives you an unknown organ for you to examine and identify through microscopy. What should you do first with the sample?
fix it with preservative
Inability to absorb digested nutrients and secrete mucus might indicate a disorder in which epithelial tissue?
Simple columnar
Glands, such as the thyroid, that secrete their products directly into the blood rather than through ducts are classified as ________.
Endocrine
A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as ________.
stratified squamous
correct statement regarding epithelia.
Stratified epithelia are present where protection from abrasion is important.
true or false Stratified epithelia are present where protection from abrasion is important.
FALSE
all epithelia have two surfaces, an apical surface and a basal surface that differ in both structure and function. the property is called polarity
True
what is dense regular tissue dominated by?
Dense regular connective tissue is dominated by collagen fibers.
You observe a uniform tissue under a microscope. There is no lumen. The material looks densely packed, but you do not observe many nuclei. It appears that there are strands of fibers running in parallel directions. What type of tissue are you looking at?
connective tissue
Which description is best for transitional epithelium?
Cells that are more cuboidal in a relaxed state but more squamous when stretched.
What are the visible characteristics of transitional epithelium?
Multiple layers of cells.
neighbors a hollow cavity called the lumen
rounded apical surfaces that resemble a tombstone shape
Identify the function of transitional epithelium.
Flexability
Where is transitional epithelium found in the body?
lining of the urinary bladder
lining of the proximal portion of the urethra
lining of the ureters
What is the only body system that contains transitional epithelium
urinary system
