Electrolytes and Water Balance

40-75% of total body weight

Average water content of the human body ranges from:

Osmolality

The physical property based on the concentration of solutes (colligative property)

• Sodium

• Potassium

• Chloride

Volume and osmotic regulation requires which electrolyte/s?

• Potassium

• Magnesium

• Calcium

Myocardial rhythm and contractility requires which electrolyte/s?

Magnesium

Regulation of ATPase ion pumps require which electrolyte/s?

• Calcium

• Magnesium

Blood coagulation requires which electrolyte/s?

• Potassium

• Calcium

• Magnesium

Neuromuscular excitability requires which electrolyte/s?

• Magnesium

• Phosphate

Production and use of ATP from glucose requires which electrolyte/s?

Sodium

It is the most abundant cation in ECF

ISE

It is the most common method for measuring sodium.

Potqssium

It is the major intracellular cation which also has a major effect on contraction of skeletal and cardiac muscles.

Chloride

Major extracellular anion involved in maintaining osmolality, blood volume, and electroneutrality

• Magnesium

• Calcium

Tetany is caused by low levels of which electrolytes?

AAS

It is the reference method for Calcium.

Liver

It is the major organ for removing lactate.

Lactate

It is an early, sensitive, and quantitative indicator of severity of oxygen deprivation
