exam 3 Flashcards
study
cranial
towards the head
caudal
towards the tail
dorsal
towards the back (spine)
rostral
towards the nose
latteral
away from the midline
distal
further away from the body
plantar
the back of the foot
abduction
movement away from the body
adduction
movement towards the body
anatomy is
the study of the body
physiology is
the study of body function
homeostasis is
is process of adapting to the external environment
4 basic functions of cell
respirate
digestion
reproduction
movement
matter is
anything that has space and mass
an atom is
the smallest unit of substance
a homegenius mixture contains
small particles that will not separate from the solvant if not shaken
suspension is
a specific type of heterogeneous particles that will separate from the solvent
covalent bonds are
strong bonds that that result from sharing electrons
three things that influence a rate of physiologic reaction
temperature
concentration
activation of energy
organic compound contain the element
carbon
what is considered universal solvant
water
carbohydrates primarily function to provide
energy
saturated fats come from
an animal
primary function of protein is
cell structure
ATP is
primary energy storage in the body
cytoplasm contain
all internal structure of cells exept the nucleus
95% of energy required by the cell is produced by
mitochandrea
cellular genetic material is composed of
DNA
RNA
fluid makes up
60% of adult animal body
80% of puppies and kittens
50% in geriatrics
without water death results in
2-4 days in dogs cats humans
electrolytes are
not equally distributed from the body
osmolality is
the measure of solutes in the fluid
miosis refers to
division of sex cells
three things that result in cellular mutation
dna
chemical exposure
radiation exposure
isotonic fluids contain
the same electrolytes in the same proportion as blood plasma
hypertonic fluid contains
more electrolytes in higher concentration than blood plasma
edema is
when there is more fluid that accumulates in the body tissue
dehydration at 10-15% results
in death
what are 4 tissue types
connective
epithelial
muscle
nervous
what are functions of epithelial tissue
protection
absorbes nutrients
sensory
filters biochemical substances
junction complexes are
flexible bonds that are between epithelial cells
functions of basal membrane
from a barrier between cell and a tissue
allows nutrient and waste diffusion in and out of the cell
cilia is
multiple hairlike projection that displays wave like motion
microvilla is
finger like projection that serve to increase surface
endocrine glands
release secretion into the blood stream
do not have ducts or tubules
exocrine glands
release secretions that act locally
have ducts or tubules
connective tissue is
vascular
contains greater percentage of of matrix than living cells
most abundant tissue type by weight
