Chapter 5-5

Question 1

What is the process by which most nutrients are absorbed in our body?

Answer 1

diffusion

Question 2

What is the process by which water components in our nutrition are moved through our body?

Answer 2

osmosis

Question 3

Define osmosis

Answer 3

movement of a solvent across a semipermeable membrane from an area of low solute concentration to high solute concentration

Question 4

what is the goal of osmosis?

Answer 4

to make the solute the same on either side of the membrane

Question 5

define tonicity

Answer 5

the relationship between the solute concentration inside the cell to outside the cell

Question 5

define hemolysis

Answer 5

when too much water is taken into a cell and it bursts

Question 6

define a hypotonic solution as it relates to red blood cells

Answer 6

a solution where the solutes in the water are lower than the solutes in the cell

Question 7

define an isotonic solution

Answer 7

when the solute of the concentration of the cell is the same inside and outside

Question 8

define a hypertonic solution

Answer 8

the solute outside the red blood cell is higher than inside

Question 9

what is crenation

Answer 9

the cell shrinks because water moves outside the cell to the solution outside of it because the solute concentration outside the cell is lower than inside.
