PRN1178 CCC2 Exam 1
1. What are the 4 main functions of water in the body
-vehicle to transport substances to and from the cell
-temperature regulation via sweat
-maintain hydrogen balance
-medium for enzymatic action for digestion
2. How much of the body is water, difference between men and woman?
-More than half, about 60%
-Men contain 50%
-Women contain 60% due to fat tissue
3. Who loses more fluid through the skin than adults
Infants, kidneys are less efficient than adults so there is less fluid absorption
4. What are age related reasons for less body water
-Less thirst
-decreased urine concentrating abilities of the kidneys
-less effective antidiuretic hormone ADH
5. What is hypovolemia?
large decrease in the volume of blood plasma
6. What is critical to maintaining homeostasis
water
, 7. What can cells not function without
water-cells will die
8. What are electrolytes? What is the main source
minerals or salts that dissolve in body fluid
main source comes from diet
9. What unit is electrolytes measured with
mEq/L
10. Electrolytes in a solution break into particles known as what?
ions from reactions between hydrogen and electrolytes
11. What are ions?
-they develop a positive electrical charge known as citations
-for each positive charge in a fluid compartment there must also be a negatively charged
anion so that a balance is maintained
12. What is the average circulating blood flow
4-6 liters
13. What are erythrocytes? where are they carried
red blood cells
carried in the plasma
