BIO102 Unit 8 Fluid and Electrolyte Balance Assignment 2
1. Identify the body’s main fluid compartments and explain the importance of
water in the body.
The importance of water in the body is for the use of Solvent, Transport,
Thermoregulation, and Lubricants.
Intracellular compartment and extracellular compartment.
2. Identify the six ions most important to the function of the body.
Sodium
Potassium
Chloride
Bicarbonate
Calcium
Phosphate
3. Define buffer and discuss the role of buffers in the body.
Buffers maintain blood pH within the normal limits of (7.35-7.45).
4. Explain why bicarbonate must be conserved rather than reabsorbed in the
kidney.
The kidneys do not excrete bicarbonate, they ADD new bicarbonate to
blood, thus reducing plasma H+ concentration (= increasing plasma pH)
5. Identify the normal range of blood pH and name the conditions where one
has a blood pH that is either too high or too low.
Blood pH within the normal limits of (7.35-7.45). 80 mmoles of bicarbonate
is lost from the body. The person is in alkalosis (in this case, their urine pH =
8.0 alkaline)
, 6. Provide specific examples to demonstrate how the urinary system responds
to maintain homeostasis in the body.
Collects waste produced by cells and removes waste from the body. It helps
maintain homeostasis By regulating the body PH, blood pressure and
eliminating waste like urea and salt.
7. Explain how the urinary system relates to other body systems in
maintaining homeostasis.
Skin, liver and lungs to remove wastes.
8. Predict the types of problems that would occur in the body if the urinary
system could not maintain homeostasis.
Due to some of the disruptions of homeostasis stated above, dehydration
could cause death. As well as super high or super low blood pressure is
fatal.
9. Contrast the composition of the intracellular fluid with that of the
extracellular fluid.
Contains only small quantities of sodium and chloride ions and almost no
calcium ions. Instead it contains large amounts of potassium and phosphate
ions plus moderate quantities of magnesium and sulfate ions, all of which
have low concentrations in the extracellular fluid. Also, cells contain large
amounts of proteins, almost 4X as much as plasma.
10. Explain the importance of protein channels in the movement of solutes.
Passive Transport (no energy) Proteins in the membrane that allow
facilitated diffusion to happen. They allow Water and Ions such as ( K+ or Cl-
or Na+) to pass through the membrane from high to low concentration.
Create channels in the membrane.
