ANATOMY STUDY GUIDE TWO

types of passive transport

What does passive mean

NO energy

what is the concentration in passive transport

high to low

what is diffusion

the movement of materials

High to low concentration until… (diffusion)

homeostasis/equilibrium is maintained (by the end it will look the same)

what is osmosis

osmosis is the movement of WATER across the cell membrane

what 2 things does osmosis have

SOLVENT AND SOLUTE

solvent (osmosis)

the thing that dissolves (water, gas)

solute (osmosis)

The thing getting dissolved (sugar, salt)

what are the three types of osmotic solutions

Isotonic, Hypertonic, Hypotonic

what are the types of passive transport

Osmosis, diffusion, and facilitated diffusion

What is the concentration in a isotonic solution

The concentration is the SAME. equals a stable cell

what is an example of a isotonic solution

An IV

what is the concentration in a hypertonic solution

higher solute concentration (salt)

what happens to the cell in a hypertonic solution

it shrivels and shrinks

what does the solute levels mean in the hypertonic solution

more solute than solvent

What happens to the cell in a hypotonic solution

Swelling (can burst)

what does the solute levels mean in a hypotonic solution

more solvent than solute

what does water do

it keeps moving until homeostasis

what is the concentration of facilitated diffusion

high to low concentration with the help of a protein

what are the two types of passive transport across tissue

dialysis and filteration

Dialysis

movements of material from high concentration to low concentration (same as diffusion expect across tissues)

what is a example of Dialysis

kidneys getting ride of waster, excess material

what is Filteration

movement of water and solutes (based on size) due to pressure
