complete solutions.
Acidosis - ANSWER An crease of acids
Aldosterone - ANSWER A hormone that regulates fluid and electrolyte balance by stimulating the
kidneys to retain more sodium and excrete potassium
Alkalosis - ANSWER An increase in bases or alkaline substances.
Antidiuretic hormone (ADH) - ANSWER A hormone released from the posterior pituitary that directs the
kidney tubules to increase water reabsorption independently of solids, which helps to dilute the
concentration of the blood.
Bicarbonate - ANSWER A main anion of extracellular fluid that is controlled by the kidneys. It is also
present in lesser amounts in the intracellular fluid (ICF). Its normal range is 22 to 26 mEq/L.
Buffer - ANSWER A substance that can bind, or form an ionic bond, with a strong acid or base to prevent
large changes in the pH of body fluids; a buffer binds with a strong acid to decrease acidity, or the buffer
binds with a strong base to decrease alkalinity of the body.
Dehydration - ANSWER A loss of fluid only, which results in the increase of electrolyte concentrations in
the remaining body fluid.
Diffusion - ANSWER A process that allows a substance to flow over naturally from an area of higher
concentration into an area of lower concentration.

Electrolyte - ANSWER A salt, that when dissolved in water conducts electricity. It is present in blood,
tissue fluids, and cells, and includes sodium, potassium, and chlorine
Extracellular fluid (ECF) - ANSWER One-third of the body's fluid that is located in the compartments
outside the cells.
Filtration - ANSWER The passage of fluid through a partial barrier that separates the fluid from certain
particles that are too large to pass through the semipermeable membrane.
Fluid Volume Deficit - ANSWER An equal loss of both fluid and the electrolytes contained in that fluid;
also known as hypovolemia.
Intracellular fluid (ICF) - ANSWER Two-thirds of the body's fluids that is located inside the individual
cells.
Intravascular space - ANSWER A space that includes the blood vessels and the heart and that holds the
plasma
Osmosis - ANSWER The process in which water moves through a semipermeable membrane from the
side where the fluid is lowest in solute concentration to the side where the fluid is highest in solute
concentration.
What the body's number one requirement to sustain life, water, food, and physical safety? - ANSWER
Oxygen
True or false
Fluid loss interferes with homeostasis and impairs body functions so much that a person can only
survive a few days without water intake - ANSWER True

True or false
The volume of fluid in the body is directly affected by the amount of water ingested and absorbed from
the gastrointestinal (GI) tract. - ANSWER True
What is most important in survival : water or food? - ANSWER Water
Where are body fluids found ? - ANSWER in one of two water compartments: the intracellular space or
the extracellular space
Interstitial space - ANSWER the areas surrounding and between the cells. This fluid is also called tissue
fluid or interstitial fluid
Distribution of body fluids - ANSWER Intracellular Fluids
Two-thirds of the body fluids are found within the cells.
Extracellular Fluids
