The hormone aldosterone functions to promote the
reabsorption of sodium
Extracellular fluids are characterized by relatively
high sodium and low potassium levels
The thirst center is located in the
hypothalamus
Transcellular fluid includes the water and electrolytes within
joint cavities
Intracellular fluids are characterized by relatively high concentrations of
potassium and phosphate
The movement of water and electrolytes between fluid compartments is regulated primarily by
hydrostatic pressure and osmotic pressure
During the act of drinking water, the desire for water is usually inhibited by
distension of the stomach
A person in a moderate environment probably would lose the greatest amount of water by means of
urine
WOTF metabolic processes is likely to serve as a source of hydrogen ions in body fluids
All of the above
The force that causes tissue fluid to enter lymphatic capillaries is
osmotic pressure
WOTF includes the greatest volume of total body water
intracelluar fluid
Acid-base buffer systems minimize pH by
converting strong acids to weak acids
WOTF is an example of a physiological buffer
renal buffer
The kidneys help to regulate the pH of body fluids by controlling the
secretion of hydrogen ions
Drinking alcohol produces a diuretic effect by
inhibiting the release of ADH
Water intoxication is caused by
hypotonic extracellular fluid
A person who is extremely dehydrated is likely to have a high fever because
Water is needed for body temp. regulation
As body fluids become more alkaline, neurons become
excitable
Obstruction of the airways leads to
respiratory acidosis
Prolonged diarrhea, in which the intestinal secretions are lost excessively, leads to
metabolic acidosis
Hyperventilation leads to
respiratory alkalosis
Prolonged vomiting in which only the stomach contents are lost leads to
metabolic alkalosis
Diabetes Mellitus in which fatty acids are converted to ketone bodies, leads to
metabolic acidosis
Ingestion of excessive amounts of sodium bicarbonate to relieve symptoms of indigestion may lead to
metabolic alkalosis
Compared to the average adult male, the average adult female body contains relatively
less water and more adipose tissue
Severe demands are placed on a person's ability to regulate body temp if body water loss exceeds
2%
T/F Any factor that alters water balance will also alter electrolyte balance
True
T/F The kidneys help to regulate the hydrogen ion concentration of body fluids by altering the rate at which hydrogen ions are secreted
True
The intracellular fluid compartment includes all Water and electrolytes enclosed by _____
cell membranes
The primary regulator of water intake is the mechanism of ____
thirst
The volume of urine produced is regulated mainly by the activity of the ____ _____ portion of the renal tubule and collecting tubule
distal convoluted
When electrolytes are deficient, a person may experience a desire to eat salty foods called _____
salt craving
The greatest loss of fluid electrolytes normally occurs as a result of ___ function
kidney
The primary mechanism that regulates the concentration of sodium ions in extracellular fluid involves a hormone secreted by the ______
adrenal cortex
Subtances that combine the hydrogen ions are called ____
bases
Somtimies the ____ groups of proteins release hydrogen ions
carboxyl
