What does the extracellular electrolyte Calcium do? correct answers Stabilizes cell membranes
and reduces permeability, transmits nerve impulses, contracts muscles (cardiac and skeletal),
coagulates blood, and forms bones and teeth, activates enzymes
What does the extracellular electrolyte Chloride do? correct answers Maintains osmotic pressure
and helps gastric mucosal cells produce hydrochloric acid
What does the extracellular electrolyte Bicarbonate do? correct answers Plays a role in acid-base
balance
Name the extracellular electrolytes. correct answers Sodium + - most abundant extracellular
Chloride -
Calcium +
Bicarbonate -
What role does the thyroid gland play in electrolyte balance? correct answers Secretes calcitonin,
which prevents calcium release from the bone
What role does the parathyroid gland play in electrolyte balance? correct answers Secrete
parathyroid hormone, which draws calcium into the blood and helps move phosphorous to the
kidneys for excretion
What role does the GI tract play in electrolyte balance? correct answers Absorbs and excretes
fluids and electrolytes
, What role do sweat glands play in electrolyte balance? correct answers Excrete sodium,
potassium, chloride, and water through sweat
What role does the heart play in electrolyte balance? correct answers Secretes ANP causing
sodium excretion
How do the lungs and liver regulate blood pressure? correct answers By regulating sodium and
water balance
Name the major electrolytes in extracellular fluid correct answers Sodium + and Chloride -
Name the most plentiful intracellular electrolytes correct answers Potassium +

magnesium +
Aldosterone is produced as the result of what? correct answers Renin-angiotensin mechanism
acts to regulate fluid volume
How does (Antidiuretic Hormone) ADH work? correct answers - Hypothalamus senses low
blood volume and increases serum which signals the pituitary gland
- The pituitary gland secretes ADH into the bloodstream
- ADH causes the kidneys to retain water
- Water retention boosts blood volume and decreases serum osmolality
What's another name for vasopressin and what does it do? correct answers Antidiuretic hormone,
it regulates fluid balance
What is plasma colloid osmotic pressure? correct answers The pulling force of albumin
