Exam 3: Objectives 70-74

Question 1

what does acidity of a solution refer to?

Answer 1

free hydrogen ion concentration

Question 2

what is the renal compensation for metabolic acidosis?

Answer 2

save HCO3- and eliminate H+

Question 3

Increased adrenal secretion of epinephrine and activity of adipose tissue; Brown adipose tissue in infants

Answer 3

non-shivering thermogenesis

Question 4

The process by which the surfaces of objects constantly emit heat in the form of electromagnetic waves

Answer 4

radiation

Question 5

The loss or gain of heat by transfer of thermal energy during collisions between adjacent molecules.

Answer 5

conduction

Question 6

which thermoreceptors have the greatest influence on body temperature?

Answer 6

peripheral

Question 7

which method of heat transfer involves direct contact?

Answer 7

conduction

Question 8

how do you calculate BMI?

Answer 8

weight (kg) divided by height squared (m)

Question 9

what is the only form of backup for respiratory alkalosis?

Answer 9

renal compensation

Question 10

what metabolic condition does diarrhea cause?

Answer 10

acidosis

Question 11

what is the most immediate buffering system in the body?

Answer 11

intra/extracelluluar blood buffers

Question 12

Water vaporizes from the skin and membranes lining the respiratory tract; the heat required to drive the process is conducted from the surface thereby cooling it

Answer 12

evaporation

Question 13

how do the kidneys primarily change H+ ion concentration in the body?

Answer 13

altering plasma bicarbonate concentration

Question 14

what is the renal compensation for respiratory alkalosis?

Answer 14

make less HCO3- and save H+

Question 15

what is the main way we regulate body temperature?

Answer 15

radiation

Question 16

what is the respiratory compensation for metabolic alkalosis?

Answer 16

decreased RR

Question 17

Oscillating rhythmical muscle contractions and relaxations at a rapid rate; All energy liberated as heat not work

Answer 17

shivering thermogenesis

Question 18

The process whereby conductive heat loss or gain is aided by movement of air or water next to the body

Answer 18

convection

Question 19

what kind of respiration is associated with respiratory alkalosis?

Answer 19

hyperventilation

Question 20

what is the respiratory compensation for metabolic acidosis?

Answer 20

increased RR

Question 21

decreased respiration causes retention of CO2, which does what to the equation?

Answer 21

shifts right

Question 22

what does high arterial H+ concentration do to ventilation?

Answer 22

stimulates ventilation

Question 23

where is the regulatory control center for temperature?

Answer 23

hypothalamus and anterior pituitary gland

Question 24

what metabolic condition does vomiting cause?

Answer 24

alkalosis

Question 25

slower breathing does what to CO2 levels?

Answer 25

increases them

Question 26

how are H+ or HCO3- levels affected in metabolic acidosis?

Answer 26

gain of H+ or loss of HCO3-

Question 27

increased respiration causes loss of CO2, which does what to the equation?

Answer 27

shifts left
