Electrolyte imbalances

Question 1

Purpose of Renin Angiotensin Aldosterone System (RAAS)

Answer 1

Regulates Blood Press. and Fluid balance by INCREASING BLOOD VOLUME AND PRESSURE

Question 2

What is Aldosterone

Answer 2

Secreted by adrenal cortex. More aldo= sodium reabsorption=water reabsorption=ecf increase. less aldo= no sodium reabsorption=sodium excreted in urine.

Question 3

Angiotensin I

Answer 3

triggers release of other hormones

Question 4

Angiotensin II

Answer 4

Causes arteries to constrict and increase cardiac output resulting in increased bp and volume. increases thirst

Question 5

ADH

Answer 5

more water resabsorption into the blood, increases sodium reabosrption.

Question 6

what is ANP

Answer 6

Hormone antagonistic to the angiotensin pathway. it decreases bp

Question 7

most abundant cation in ICF

Answer 7

Potassium

Question 8

Role of Potassium

Answer 8

Electric conductivity in muscles and nerves

Question 9

Calcium balance importance

Answer 9

Blood coagulation, membrane permeability, cell secretion, muscle contraction

Question 10

What regulates calcium balance

Answer 10

Parathyroid hormone (PTH) and calcitonin

Question 11

Major anion in ECF

Answer 11

Chloride

Question 12

ECF electrolytes

Answer 12

Na: nerve muscle cell interaction, CL: osmotic pressure
Ca: stabilize cell membrane and reduce permeability, coagulation, bone and teeth

Question 13

ICF Electrolyes

Answer 13

K: Cell excitability, nerve conduction, muscle contraction
PO4: Energy metabolism, w/calcium it mineralizes bones and teeth
Mg: catalyst for enzyme reaction, neuromusclur contract, cardiovascular system.
