urine production rate

how much urine is produced in a given time

it would go up

What would happen to urine pH after ingesting large amounts of water?

6.0

average pH of urine

1,003-1.040

normal specific gravity of urine

tidal volume

The amount of air inhaled or exhaled in one breath during normal respiration.

expiratory reserve volume

The maximum amount of air that can be expelled from the lungs after a normal exhalation.

vital capacity

this is the total amount of air that can be exchanged at will

respirometer

device that measures inspiration and expiration

chronic obstructive pulmonary disease

Emphysema, Asthma, Chronic Bronchitis are examples of

restrictive pulmonary disease

Pulmonary Fibrosis, Respiratory Distress Syndrome are examples of

600mL/min

renal plasma flow (RPF) is approximately

125mL/min

Glomerular filtration rate (GFR) is approximately

clearance (CL)

The volume of plasma cleared of a given solute in a given time

inspiratory capacity

The maximum volume of air that can be inspired after a normal expiration

expiratory reserve volume

the the extra amount actively (forcibly) exhaled after a normal exhalation.

functional residual capacity

Your functional residual capacity (FRC) is best known as the

total lung capacity

The total volume of air in the lungs after maximum inhalation, including all lung volumes.

residual volume

The minimum amount of air always present in the respiratory system, after blowing out all you can is called

1000ml

around how much air is left in the lungs after maximal expiration?

70% or more

normal FEV1/FVC ratio

carbon dioxide

The most important chemical regulator of respiration is

increase the rate of breathing.

An increase in the level of carbon dioxide in the blood will

hyperventilation

Under which condition did we hold our breath the longest

rebreathing

Under which condition did we hold our breath shortest?

net reabsorption

if renal clearance is less than GFR, what happened to the substance?

net secretion

if renal clearance is more than GFR, what happened to the substance?

neither secreted or reabsorbed

if renal clearance is equal to GFR, what happens to substance?

specific gravity

the ratio of a substance's density to the density of water
