How do different types of molecules (water, glucose, oxygen,
sodium, chloride) cross cell membranes and travel between
different organs? - THE CORRECT ANSWER -Cell membrane is
semipermeable to water. Oxygen move across cell membranes
simple diffusion, a process that requires no energy input and is
driven by differences in concentration on either side of the cell
membrane. Food is broken up through digestion and diffuse
into the blood through microvilli in the intestinal wall.
How is water regulated in your body? - THE CORRECT
ANSWERHomeostasis
What is osmosis and what does it have to do with water
balance? - THE CORRECT ANSWER -The diffusion of water to
create an equilibrium with salt.
Where does the water in your body come from? - THE CORRECT
ANSWER -Liquids, foods and cellular respiration.
How does your body eliminate water? - THE CORRECT
ANSWERThrough urinating, sweating, and feces.
, Which organ systems are involved in water balance and what is
their role? - THE CORRECT ANSWER -kidney regulates by
controlling water concentration in blood plasma
What happened to Cynthia Lucero? - THE CORRECT
ANSWERThrough the consumption of too much water she
flooded her cells to balance the equilibrium of solutes and thus
caused swelling of the cells
Is Gatorade hypotonic or hypertonic to the blood of a normal
person? - THE CORRECT ANSWER -gatorade is hypotonic to the
blood (more sodium outside cell) diluted by gatorade
How does cholera affect water homeostasis? - THE CORRECT
ANSWER -Cholera causes dehydration.
If 2 solutions are separated by a semipermeable membrane
(permeable to water) and side A is hypertonic to side B, which
way will the water molecules be most likely to move? - THE
CORRECT ANSWER -To side B to dilute the solutes
How is the structure of the small intestine related to its
function? - THE CORRECT ANSWER -Absorption by osmosis
through the cell walls into the vascular capillaries inside the villi
How are glucose levels regulated in your body? - THE CORRECT
ANSWER -(homeostasis) Regulated through the liver, pancreas,
and muscles
