Intro to Physiology Flashcards
what are the main tissue types?
Epithelial, Muscle, Neural, and Connective
What does epithelial tissue do?
create a barrier between 2 environments
what are the roles of epithelial tissue?
1) . protection
2) . secretion
3) . regulate movement of molecules
two main types of epithelial tissue?
Simple and stratified
types of epithelial tissue based on shape
squamous, cuboidal, columnar
structure and function of simple squamous epithelium
single flat layer - important for diffusion and filtration
where would you find simple squamous epithelium?
1) . capillary wall; 2). pulmonary alveoli;
3) . covering visceral organs;
4) . lining body cavities
structure and function of simple cuboidal epithelium
single layer, cube shaped; excretion, secretion, or absorption
location of simple cuboidal epithelium
1) . surface of ovaries,
2) . linings of kidney tubules, salivary ducts, and pancreatic ducts
structure and function of simple columnar epithelium
single layer; protection, secretion and absorption
where would you find simple columnar epithelium?
lining of most digestive tract
structure and function of simple ciliated columnar epithelium
single layer (ciliated), transportive role through ciliary motion
location of simple ciliated columnar epithelium
lining of uterine tubes
structure and function of pseudostratified ciliated columnar epithelium?
single layer, irregular shaped, many goblet cell’ protection, secretion, ciliary movement
location of pseudostratified ciliated columnar epithelium
lining of respiratory passageways
where would most simple epithelia be found?
covering visceral organs, linings of body cavities, tubes, and ducts
where would most stratified epithelia be found?
epidermal layer of skin; linings of body openings, ducts, and urinary bladder
structure and function of strat squamous epi
protection
location of strat squamous epi
epidermis; linings of oral and nasal cavities
structure and function of strat cuboidal epi
strengthening of luminal walls
