1020 MODULE 2 BODY FLUID

Question 1

Bodily Fluid Compartments

Answer 1

Intracellular- compromised in the cell.
The extracellular- environment outside the cell
the extracellular environment has a blood supply- plasma and interstitial.
BLOOD PLASMA AND INTERSTITIAL ARE NOT TOGETHER

Question 2

What is plasma

Answer 2

yellow pale liquid that is 92% water and 8% other– nutrients, gases, ions, proteins

Question 3

blood plasma

Answer 3

a) is mostly made up of proteins, gases, ions, nutrients
b) is usually hypertonic to red blood cells
c) compromises part of the interstitial fluid
d) is usually isotonic to the red blood cells

Question 4

Chemical Composition

Answer 4

Potassium is higher inside the cell

Question 5

Which ion has the highest concentration in the intracellular fluid

Answer 5

remember that intracellular fluid is inside the cell and inside the cell, potassium is more.

Question 6

Why is there a difference in the ionic compartment between inside and outside the cell

Answer 6

• this is caused by the cell membrane which is also called the plasma membrane
• this forms a physical barrier between the intracellular and extracellular fluid
• this selectively permeable membrane allows some substances in while some macromolecules out.
  membrane has special channels, pores, and special transport systems
