function of tissues
what is the muscularis composition?
-causes contractions(mixing) and peristalsis(movement) w/in the gi tract -inner circular and outer longitudinal layer of smooth muscle to mix and move food
what is serosa's composition?
-outermost laye:covers and protects -areolar connective tissue,covered by a simple squamous epithelium
what is the function of simple columnar epithelium?
absorption, secretion of mucus, enzymes and other substances
what is the simple squamous tissues function?
allows passages of materials by diffusion and filtration in sites where protection is not important
what are the connective tissues?
areolar (loose) adipose bone cartilage
what is the cardiac muscles function?
as it contracts it propels blood into the circulation involuntary control
what is the connective tissues function?
connect, bind and support
what is bones function?
it supports and protects
what are the smooth muscles characteristics?
long narrow cells tapered at each end one nucleus per cell non striated move materials
what is the skeletal muscles characteristic?
long parallel and cylindrical
what is elastic cartilage function?
maintains the shape of a structure while allowing great flexibility
what is adipose tissues functions?
provides reserve food fuel, insulates against heat loss and supports and protects organs
what is the function of simple cuboidal tissue
secretion and absorption
what is the function of psuedostratified columnar epithelium
secretion particularly mucus propulsion of mucus by cilary action
what does keratinized mean?
skin on top
what are the muscle tissues?
smooth cardiac skeletal
what are the epithelial tissues?
squamous, cuboidal, columnar,pseudostratified columnar, transitional
what is the characteristics of the nervous tissues?
star shaped cells large nucleus large nucleolus
what is the nervous tissues functions?
transmit impulses regulate through neuron impulses
what is the bloods function?
transport of respiratory gases, nutrients, wastes and other substances
what is the skeletal muscles function?
voluntary movement
what is the loose areolar connective tissues function?
wraps and cushions organs
what is the function of the muscle tissue?
provides heat
what is that submucosa composition?
-thick,vascular layer of connective tissue where absorbed molecules enter blood and lymphatic vessels -contain glands and nerves
what is the nervous tissues function?
generate and transmit nerves
what is a tissue?
group of cells, similar in structure, which perform common or related functions.
what is an organ
group of tissues, similar in structure, which perform common or related functions
what types of cartilage are there?
hyaline elastic fibrocartilage
what is the mucosa's composition?
innermost absoorpive & secretory layer folder to upper absorptive layer contains muus secreting goblet cells
what is one of the cardiac muscle characteristics
intercalated discs
what are the 4 layers of the gi tract?
mucosa,submucosa,muscularis, and serosa
what are the nervous tissues?
neurons neuroglia
what is the smooth muscles function?
propels substances or objects along internal passageways
what is a function of the epithelial tissue?
protects from physical and chemical injury
what is the function of transitional
stretches readily and permits distention of urinary organs by contained urine
what is histology?
study of tissues
what is hyaline cartilage function
supports and reinforces
what is fibrocartilage function?
tensile strength with the ability to absorb comprehensive shock
