CHF Quiz Question 15
So our blood vessels have about a gallon of blood in them.

1/2 gallon
red blood cells

1/2 gallon water

1 gallon
blood

which is a perfect fit for the body's blood vessels

CHF is kinda like Uncle Ernie when it comes to mixing water into our blood.

This is the amount of water that's supposed to be in our blood.

2 quarts

1/2 gallon

but when you have chf, you have this much water in your blood (too much!)

3 quarts!  too much!

If you have CHF, You have more blood in your blood vessels (Because there’s extra water in it).
normally, Your body holds one gallon of blood.

2 quarts
red blood cells

2 quarts water

1 gallon
blood

That's what's in this guy
But extra water can be a problem.

if you try to put an extra quart of water into a container of blood…
In the same way, if you put too much blood in your blood vessels…
…It makes High Blood Pressure

And then some of that extra water can leak out of the blood vessels

Into the
lungs

Into the
leg

Into the
belly

Into the
other leg

Narrowed, constricted
blood vessel but with just as much blood!
