chapter 5 - tissues Flashcards
that tissue which conducts the specific function of the organ and which usually comprises the bulk of the organ
parenchyma
supports the parenchyma; comprises everything else (connective tissues, blood vessels, nerves, ducts)
stroma
anchors epithelium to underlying connective tissue
basement membrane
single layer of thin, flattened cells through which substances pass easily (gas exchange, filtration)
simple squamous epithelium
Where are simple squamous located?
Lungs, alveoli
Single layer of cube-shaped cells; carries on secretion and absorption functions
simple cuboidal
Where is simple cuboidal located?
Kidney tubules and ducts
Single later of elongated cells whose uncle are near the basement membrane; contains goblet cells that secrete mucus; have microvilli on top
simple columnar
Where is simple columnar located?
Lines the uterus and portions of the digestive tract (small intestine, large intestine, and stomach)
appears stratified, where nuclei are at two or more levels, cilia is present on apical surface
pseudostratifed columnar
Where are pseudostratifed columnar located?
Line the respiratory passages
composed of many layers of cells, top layers are flattened, where they protect underlying cells from harmful environmental effects
stratified squamous
Where is stratified squamous located?
Superficial portion of skin, oral, vaginal, and anal cavities
composed of two or three layers of cube-shaped cells; important for containment
stratified cuboidal
Where is stratified cuboidal located?
Lines the ducts of mammary glands, sweat glands, salivary glands, pancreas
two layers of elongated cells, not ciliated
stratified columnar
