tissues and epithelial
How are epithelial tissue classified?
By shape and number of layers
lacks blood vessels but has nerves
avascular but innervated
Abundant nonliving extracellular matrix
connective
Anchors, packages, and supports body organs
connective
endocrine
ductless, produces hormones
Cells may absorb, secrete, and filter
epithelium
Lines body cavities and covers the body's external surface
epithelium
synthesizes hormones
epithelium
Which of the following are functions of epithelial tissue? (check all that apply)
filtration, secretion, protection, excretion, absorption, sensory reception (SREAFPS)
exocrine
merocrine, holocrine, apocrine, secrete products to body surface, release by exocytosis
Pumps blood, flushes urine out of the body, allows one to swing a bat
muscle
major function is to contract
muscle
Most involved in regulating and controlling body functions
nervous
Transmit electrical signals
nervous
forms nerves and brains
nervous
has a free surface, apical surface
polarity
constantly dividing
regeneration
Where is ciliated epithelium found?
respiratory tract
How does the function of stratified epithelium differ from the function of simple epithelium?
simple allows for filtration and stratified allows for protection
lining of the stomach
simple columnar
tubules of kidney
simple cuboidal
Forms the serous membrane; a single layer of flattened cells
simple squamous
alveolar sacs of the lungs
simple squamous
fit closely together, specialized junctions
specialized contacts
epidermis of skin
stratified squamous
lining of the esophagus
stratified squamous
attached and supported by basement membrane
supported by connective tissue
Groups of cells that are anatomically similar and share a function are called
tissues
Lining of the bladder; peculiar cells that have the ability to slide over each other
transitional
True or False. Endocrine and exocrine glands are classified as epithelium because they usually develop from epithelial membranes.
