Question 1

Question
Sodium (Na+) is the main [blank_start]cation[blank_end] in the ECF ([blank_start]extracellular[blank_end] fluid). It determines the ECF volume, and therefore, influences [blank_start]blood pressure[blank_end]. It's standard range of concentration in the ECF is between 135 and 145 mmol/L. ([blank_start]Milimol per litre[blank_end]).
Answer
  • cation
  • extracellular
  • blood pressure
  • Milimol per litre
  • Megamol per litre

Question 2

Question
[blank_start]Calcium[blank_end] (Ca2+) is the cation most important for your [blank_start]bones[blank_end], as well as neurotransmission, blood clotting, and muscle contraction. It's normal concentration in the [blank_start]plasma[blank_end] is 2.2—2.6 mmol/L.
Answer
  • bones
  • Calcium
  • plasma

Question 3

Question
Glucose is especially important as it is used to make ATP. [blank_start]Low glucose levels[blank_end] harm neurons and [blank_start]high glucose levels[blank_end] can cause acute or chronic problems. The normal fasting glucose [blank_start]concentrtion[blank_end] in the blood is 3.5—6.0 mmol/L. When not fasting it can reach 8 mmol/L.
Answer
  • Low glucose levels
  • high glucose levels
  • concentration

Question 4

Question
Potassium (K+) is the main cation in the ICF ([blank_start]Intracellular[blank_end] fluid). It is the main determinant of RMP, resting [blank_start]membrane[blank_end] potential. Its normal concentration in the [blank_start]ECF[blank_end] is 3.5—5 mmol/L.
Answer
  • Intracellular
  • membrane
  • ECF

Question 5

Question
Normal Na+ conc. in the ECF is ____
Answer
  • 135—145 mmol/L
  • 1.35—1.45 mmol/L
  • 3.5—4.5 mmol/L

Question 6

Question
Normal calcium ion concentration in the plasma is ____
Answer
  • 3.5—5 mmol/L
  • 2.2—2.6 mmol/L
  • 2.3—2.6 mmol/L

Question 7

Question
The normal fasting glucose concentration in the blood is ______
Answer
  • 3.5—7 mmol/L
  • 35—70 mmol/L
  • 3.5—6 mmol/L

Question 8

Question
Normal K+ concentration in the ECF is ____
Answer
  • 3.5—5 mmol/L
  • 3.5—6 mmol/L
  • 2.2—2.6 mmol/L
