Intracellular Fluid (ICF)

This is the cytosol of the cell.




This is the fluid portion inside the cell.

Extracellular Fluid (ECF)

This is the fluid outside of the cell



Solute

Solutes are the dissolved particles in the fluid in the ICF and the ECF.




Solutes can be : Ions/Minerals/ Sugars/Salts



Solution



This is the combination of solutes and water inside the cell and outside the cells.




The ICF consists of a solution made of water and solutes.


The ECF consists of a solution made of water and solutes.



Solution Concentration

The combination of water and solutes inside the cell will equal 100%.


This is disregarding the organelles of the cell.


The combination of water and solutes outside the cell will equal 100%.


If the solute concentration rises, the water concentration _

Decreases

If the water concentration rises, the solute concentration _

Decreases




Hypotonic

This is the solution that consists of a lower concentration of SOLUTES when compared to another solution.



Hypertonic

This is the solution that consists of a high concentration of SOLUTES when compared to another solution.

Isotonic

This is the solution that consists of the same concentration of solutes when compared to another solution.

Water moves from _

Hypotonic to hypertonic

As soon as the cells (in what part of the brain) lose about 2% water, what do the cells trigger?

Hypothalamus cells trigger the thirst mechanism

As soon as the solute concentration in the blood rises, what detect the increase and initiate what to happen?

Receptors in the hypothalamus trigger the thirst mechanism

Popcorn will cause the bloodstream to become what?

Hypertonic to the cells

Normal function of the human body to prevent dehydration

1. Hypothalamus releases ADH (antidiuretic hormone)


2. This hormone targets special structures of the kidneys


a. Kidneys normally take water and send it to the toilet


b. this hormone will cause the kidneys to put some of the water back into the bloodstream and therefore less will go into the toilet


3. By putting water back into the bloodstream, less goes to the toilet and more goes back to the cells

How does the alcohol in beer effect ADH?

Alcohol inhibits the action of the ADH hormone.


Without the action of the hormone, the kidneys are not told to put water back into the bloodstream.


A lot of water will leave the kidneys and go to the toilet


The alcohol causes the person to become thirstier and thirstier
