Both intracellular proteins (such as hemoglobin) and extracellular proteins (such as plasma proteins) can act as chemical buffers
When blood starts to become more alkaline than normal the renal tubules begin to
secret bicarbonate while reabsorbing H+ in exchange through type B cells
In the brain ADH ____ the thirst center and in the kidneys ADH causes an increase in water ____
Calcium harden bone and teeth, but its levels are carefully controlled throughout the body. Low levels of calcium within cells are maintained by
pumps that move calcium out of cells or into the sarcoplasmic reticulum
When compared with the effects of blood pressure and osmolarity on fluid intake, the effects of saliva and stomach distention are
more immediate but less accurate
Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of
Emphysema causes a decrease in the surface area of the respiratory membrane and thereby leads to respiratory
Activation of the parasympathetic nervous system triggers renin release from the JG apparatus of the kidneys
Renal compensation to a decrease in blood H+ levels is to increase the activity of type
B cells to excrete more bicarbonate
A comparison of the two major body fluid compartments revels that
Two thirds of the total fluid is within our cells and one third is outside our cells.
If a rummer drinks too much water before a marathon they run a risk of water intoxication also known as
The bicarbonate system is composed of H2CO3 and HCO3-. Which statement accurately describes these molecules
H2CO3 is a weak acid and HCO3- is a weak base
To buffer the body's extracellular fluid compartment, dihydrogen phosphate acts as a strong base and prevents acidosis of the plasma

Atrial natriurtic peptide causes ____ of afferent arterioles and _____ of mesangial cells
The plasma of our blood constitutes ____ than half of the fluid in our body; plasma is part of the ____ fluid.
Researchers have inflated balloons inside the stomachs of experimental subjects and have found that distention of the stomach causes thirst to
Insulin causes blood plasma levels of potassium to ____by_____activity of the Na+/K+ pumps
If an individual's respiratory rate decreases, then blood CO2 levels
Rise, blood H+ levels rise, and blood pH falls
Elderly individuals generally have a ____ percentage of body fluid and are therefore ____ prone to fluid imbalances
If someone in an accident suffered severe burns as well as hemorrhage, they would be at high risk for
Decreased stretch of baroreceptors within the aorta and carotid arteries results in stimulation of the hypothalamus; the stimulation increases ADH secretion. True or False?

If someone runs a marathon through a desert while eating pretzels and not drinking water, their plasma osmolarity
Rises and becomes hypertonic to the interstitial and intercellular fluid compartments
When compared to extracellular fluid, intracellular fluid contains
More potassium and more negatively charged proteins
Feeling of thirstiness are about on by
Decreases in salivary secretions and increases in blood osmolarity
