Cytology Flashcards
study of the cells
cytology
structure that encloses all the parts of the cell
Cytoplasm
responsible from what comes and or passes through a cell
phospholipid bilayer
cell membrane
primary carrier of energy in the cell
ATP (adenosine triphosphate)
Selective Permeability
Cell membrane
pagpasok ng water sa membrane
Osmosis
T or F
High water will move to Higher concentration to lower Concentration
T
can either be ACTIVE or PASSIVE
diffusion
more solvent extracellularly will cause an INWARD direction of water
Hypotonic
ex Saline and Tap Water
more solute extracellularly will cause an OUTWARD direction of water
Hypertonic
ex Corn Syrup
T or F
water travels where there are more SOLUTES and less SOLVENT
T
that’s why in hypertonic (corn syrup) experiment the water shrink/crenation because the water are attracted to solutes
the ability of a solution surrounding a cell to lose or gain water
Tonicity
smallest unit of life
cell
endocrine and exocrine are types of what transport?
Active Transport
osmosis, diffusion, facilitated diffusion
Passive Transport
lower concentration of impermeant solutes
cell swelling or lysis
HYPOTONIC Solution
higher concentration of impermeant solutes
cell shrinking or crenation
HYPERTONIC Solution
water concentration is equal
ISOTONIC Solution
1.2% NaCl in Mammalian Blood
HYPERTONIC SOLUTION
0.75% NaCl in Mammalian Blood
HYPOTONIC SOLUTION
0.9% NaCl in Mammalian Blood
ISOTONIC SOLUTION
net diffusion of water across a selectively permeable membrane from a
region of high water concentration to a region of lower concentration
Osmosis
only allows solvent molecules
allows both solvent and solute molecules to move freely.
diffusion
allows solvent and solute to come pass through
5 factors affecting OSMOSIS
1 Osmolality 2 Water Concentration 3 Osmotic Pressure 4 Temperature 5 Hydrostatic Pressure
what will happen to your blood if you jump on a cold swimming pool?
BV constricts making it harder for blood to flow
amount of solvent concentration within two specific bodies with
a semi-permeable membrane between them
WATER CONCENTRATION
there is faster movement and higher collision of molecules and
increased rate or amount of flow, therefore it could pass the
membrane faster
TEMPERATURE
amount of solute concentration within two specific bodies with a
semi-permeable membrane between them
OSMOLALITY
the pushing force of water
HYDROSTATIC PRESSURE
