Tissues Flashcards
in kidneys epithelium both:
absorbs and filters
Are epithelial tissues vascular or avascular?
Avascular
most concerned with absorption, secretion and filtration
Simple epithelia
usually forms membranes where filtration/ exchange of substances by rapid diffusion occurs. ;
Simple squamous epithelium
Simple squamous is found in:
air sacs of lungs (alveoli)
common in glands (saliva glands & pancreas)
Simple cuboidal epithelium
forms the wall of kidney tubules and covers surface of ovaries
Simple cuboidal epithelium
lines entire length of digestive tracts from the stomach to the anus
Simple columnar epithelium
their nuclei appear at different heights; gives false pseudo impression ; absorption & secretion
Pseudostratified columnar epithelium
two cell layers; epithelial function in protection
Stratified epithelia
most common srat epithilium in the body ; consist of many layers
Stratified squamous epithelium
found in sites that receive good deal of abuse / friction (skin mouth esoph)
Stratified squamous epithelium
both of these are found in ducts of large glands
stratified cuboidal
stratified columnar
forms lining of urinary bladder, ureters & urethra
Transitional epithelium
make and secretes product
Gland
connects body parts; found everywhere; most abundant & widely distributed tissue type
Connective tissue
protects, supports, cushions & insulating body tissues
Connective tissues
Tendons and ligaments are vascular or avascular?
Avascular
Connective tissues are vascular except tendons & ligaments. T/F
