Terms in this set (45)
water within the blood vessels
includes cerebrospinal fluid, the aqueous and vitreous humors in the eye, synovial fluids of joints, serous fluids within body cavaties, and grandular secretions
most water is located in this compartment
water located between the cells
hypervolemia refers to an increase in this water compartment
also called tissue fluid
largest extracellular fluid compartment
fluid of this compartment empties into the subclavian veins.
poor skin turgor is caused by a decrease of fluid within this extracellular compartment
plasma concentration of this ion determines pH
chloride usually follows the movement of this cation
cheif extracellular cation
most diuretics work by blocking the renal reabsorption of this cation
over 99% of this cation is stored in the bone and teeth
neutralizes a base
cheif intracellular cation
hyperkalemia and hypokalemia refer to abnormal plasma concentrations of this ion
many diuretics cause kaliuresis, thereby causing a loss of this ion
hypercalcemia and hypocalcemia refer to abnormal concentrations of this ion
aldosterone causes the kidneys to excrete this ion int the urine
An increase in this cation causes acidosis
Regulated by parathyroid hormone (PTH)
Aldosterone stimulates the kidney to reabsorb this cation
The respirtory system is most sensitive to the plasma concentrations of this cation
carbon dioxide is transported in the blood in this form
What is the average adult intake of water in 24 hours?
Wich organ is the primary regulator of water output?
is released by the posterior pituitry gland when the blood volume decreases
is the salt-retaining hormone
What type of drug is most likely to cause diuresis?
A drug that blocks the tubular reabsorption of Na+
Water usually follows the movement of wich ion?
Poor skin tugor is?
indicative of dehydration
What does pH measure?
H+ concentration [H+]
prevents changes in pH
What is the normal range of blood pH?
7.35 to 7.45
First line of defense in regulation of acid-base balance?
Why is an older adult mor prone to dehydration?
An older adult retains excessive sodium
Why do patients in kidney failure develop acidosis?
The kidneys cannot eliminate H+
defeciency of body water
Necessary for nerve impulse conduction, andhelps maintainbody fluid balance
The primary mechanism regulating sodium comsentration
Excess Na+ in blood and is the result of excess water loss or increased Na+ intake
stimulates the distal tubule of the nephron to reabsorb sodium
decrease in plasma pH below 7.35
