35 Cards in this Set

  • Front
  • Back
squamous
flat shaped of epithelial cell
Stratified 2
more than one layer of cells

some touch basal lamina
diffusion 2
spontaneous tendency of a substance to down its concentration gradient

moves from high concentration to low concentration
gall bladder
organ that stores bile and releases it as needed into the small intestine
digestion
process of breaking down food into molecules small enough for the body of absorb
liver 2
largest organ inside the vertebrate body

produces bile, prepares nitrogenous wates, and detoxifies poisonous chemicals in blood
cholera
closes down resorption of H2O in small intestine
facilitated diffusion
spontaneous passage of molecules and ions, bond to specific carrier proteins, across a biological membrane down their concentration gradient
esophagus
channel that conducts food, by peristaltis from the pharynx to the stomach
Reticular fibers 2
very thin, branched fibers made of collagen

form tightly wovem fabric that is continuous w/ collagenous of ECM
active transport 2
movement of a substance across a biological membrane against its concentraion gradient

helped by energy imput and transport proteins
lacteal(2)
the lymph vessel extending into the core of an intestinal villus

serves as a destination for absorbed chylomicros
abosorbtion 2
uptake of small nutrient molecules by an organisms own body

third main stage of processing
peristatis
rhythmic waves of contraction of smooth muscles that push food through the alementary canal
extracellular matrix ECM 2
holds animal tissue cells

protein and polysaccherides
Muscular tissue 2
long muschle cells

capable of contracting when stimulated by nerve impulses
villus
finger-like projection of the inner surface of the small intestine
sphincter 2
ring like valve

consists of modified muscles in a muscular ring
cell
makes up tissue
columnar
column shape of one type of epithelial cell
simple tissue (2)
single layers of cells

all touch basal lamina
small intestine 2
largest part alementary canal

site of enzymatic hydrolysis of food macromolecules and the absorption of nutrients
Nervous tissue
made of neurons and supportive cells
cuboidal
cubic shape of epithelial cell
collagen fibers 4
gkycoprotein in ECM (animal cells)

forms strong fibers

found in connective tissue

most abundant protein
tissue
integrated group of cells with a common structure and function
Pseudostratified 2
single layered

appears stratified because cell layers vary in length
epithelial tissue 2
sheete of tightly packed cells

line organs and body cavaties
connective tissue 2
functions to bind and support other tissues

sparse poulation of cells through extracellular matrix
elastic fibers 3
long threads made of proteins (elastin)

provide rubbery quality to ECM

complements nonelastic strength of claagen fibers
Pharynx
area in the vertebrate throat where air and food passages cross
salivary gland 2
exocrine glands associated with oral cavity

contains substances to lubricate food, adhere together chewed pieces into a bolusm and beging the process of chemical digestion
Organ 2
specialized center of body functions

composed of different types of tissue
ciliated 2
type of protazoan

moved by means of cilia
pancreas 3
gland with dual functions

non-endcrine portion secretes digestive enzymes and an alkaline solution into the S.I. through a duct

endocrine produces and secretes insulin and glucagon into the blood
