17
Q

result when pressure of a fluid forces particles thru a filtering membrane; occur in Kidneys

A

Filtration rate

18
Q

Higher [H+] = lower pH

A

Acid

19
Q

Lower [H+] = higher pH

A

Base

20
Q

influenced by [H+], higher [H+] = LOWER pH (Acidic), lower [H+] = HIGHER pH (Basic)

A

pH

21
Q

a soLn that can resist pH change upon addition of an acidic or basic components (Chemical Buffer sys., Respiratory Mechanisms, Renal Mechanisms)

A

Buffer

22
Q

Stimulates brain & Arterial receptors > Respiration rate(UP) > Blood CO2(DOWN) > Blood H2CO3(DOWN) > pH(UP)

Result from Hyperventilation, causes nausea, numb, muscle fatigue, hand tremor (pH HIGHER then 7.45)

A

Respiratory Alkalosis

23
Q

Stimulates brain & Arterial receptors > Respiration rate(DOWN) > Blood CO2(UP) > Blood H2CO3(UP) > pH(DOWN)

result from Hypoventilation, causes fatigue, drowsiness, headache (pH LOWER than 7.35)

A

Respiratory Acidosis

24
Q

Hyperventilation

A

CO2 is eliminated faster than its produced

25
Q

Hypoventilation

A

CO2 builds up
