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
