26 Cards in this Set
- Front
- Back
|
anatomy
|
science of body parts and relationships
|
|
|
physiology
|
the science of body functions and how they work
|
|
|
element
|
the purest form of a substance that cannot be broken down any further
|
|
|
Isotopes form an element that has:
|
1. same proton or atomic #
2. Different # of neutrons 3. Different mass # (p+n) |
|
|
Diagnostic
|
obtain information
|
|
|
Theraputic
|
having a direct beneficial effect(shrink or destroy a mass)
|
|
|
Chemical Compounds
|
Lose individual identity when combined
Once combined, will require a significant amount of energy to separate Like a "marriage" |
|
|
Mixtures
|
Maintain individual characteristics
can be separated by physical means Like they are simply "dating" |
|
|
Properties of water:
|
most common compound on earth
universal solvent(greatest in amt) universal lubricant can start chemical reactions(drink) can be the result of a chemical reaction(urinate) high rate of fusion-take alot of energy to freeze high rate of vaporization-takes a lot of energy to boil |
|
|
solvent
|
chemical present in greater amount
|
|
|
solute
|
chemical present in lesser amount
|
|
|
acid
|
comound that dissolves in water forming charged particles
pH less than 7 |
|
|
base
|
compound dissolves in water forming OH- ion
pH greater than 7 |
|
|
Factors Regulating uptake in a cell
|
~size-the smaller, the better. Smaller things pass easier
~charge-charged ions should be attracted to charged channels ~Lipid soluble-membrane is 70% lipid so it would be easiest if it was a lipid ~Carrier-mediated-if you can't get the molecule in the membrane, attach it to a chemical desirable to the cell(glucose) |
|
|
endocytosis
|
abosorption of molecules in the cell
|
|
|
exocytosis
|
cell is "out"
|
|
|
phagocytosis
|
cell eating
|
|
|
pinocytosis
|
cell drinking
|
|
|
Active transport
|
means to take in something; requires energy
(phagocytosis, pinocytosis, exocytosis) |
|
|
passive transport
|
reqiures no energy(diffusion)
|
|
|
Isotonic Solution
|
Concentration identical on both sides of the membrane. :) don't have to work
|
|
|
osmosis
|
movement of water
|
|
|
hypotonic solution
|
concentration higher on the inside of the cell :( cell has to make a change
|
|
|
hypertonic solution
|
concentration is much lower inside the cell :( cell has to make a change
|
|
|
hemolysis
|
swelling of the cell
|
|
|
crenation
|
shrinking of the cell
|
