Exam 1: Lab 2 Rates of diffusion, Osmosis, and filtration

Question 1

the nutrients that reach cells come from

Answer 1

the blood plasma

Question 2

from the plasma, nutrients and fluid are filtered through

Answer 2

the capillary wall to the tissue fluid

Question 3

after being filtered to the tissue fluid, nutrients then…

Answer 3

diffuse through the tissue fluid to the cell membranes

Question 4

various process move solute across the cell membrane and into

Answer 4

cytoplasm

Question 5

filtration is the major process that

Answer 5

moves fluid and solutes out of the plasma and into the tissue fluid

Question 6

filtration occurs because of a

Answer 6

hydrostatic (fluid) pressure difference on two sides of the capillary wall.

Question 7

the high hydrostatic pressure in the capillary

Answer 7

forces fluid and solutes out of the capillary through the capillary pores

Question 8

only what is filtered through the capillary

Answer 8

only solutes small enough to fit through the capillary pores

Question 9

the rates of filtration and diffusion affect

Answer 9

affect the number of molecules entering the tissue fluid and reaching cells

Question 10

cell survival depends on

Answer 10

enough nutrients and oxygen molecules reaching each cell

Question 11

Question 13

if there is no protein present

Answer 13

solution will be light blue

Question 14

test for glucose

Answer 14

• add Benedict’s reagent

Question 15

if glucose is present

Answer 15

solution will turn green or orange

Question 16

if glucose is not present

Answer 16

solution will be blue
