1

What are the concentrations of K+ inside the cell? What about outside?

K+ ion concentrations are around 155mM within the cell, while they are around 4mM outside of the cell

2

What are the concentrations of Na+ ions within the cell? What are concentrations outside?

Na+ ion concentrations within the cell are around 12mM - outside of the cell Na+ concentrations are around 145mM

3

What is a low blood level of K+ called? What about a high blood K+ level?

- low K+ = hypokalaemia
- high K+ = hyperkalaemia

4

What is the most common cause of hypokalaemia?

The use of diuretics, or pills that cause urine production

5

Is hypokalaemia normally mainly symptomatic or asymptomatic?

Asymptomatic

6

What are the concentrations of Ca2+ ions within the cell? What are concentrations outside?

Concentrations of Ca2+ within the cell are around 1x10^-7 M - outside of the cell Ca2+ concentrations are around 1-1.5mM

7

What tissue type are abnormal levels of Ca2+ in the body notably associated with?

Muscle tissue - particularly the heart

8

What are abnormally low Ca2+ levels known as? What are abnormally high levels of Ca2+ known as?

Abnormally low Ca2+ is called hypocalcemia - abnormally high calcium is know as hypercalcemia
