metabolic alkalosis

,Give this one a try later!


increased pH not due to ventilation




when is the first heart sound heard?


Give this one a try later!


when the atrioventricular valves slam shut




if the pH balance comes from a metabolic pathology, how will carbon levels be
affected?


Give this one a try later!


carbon levels will not be consistent and so will not affect pH. (Normal or
high carbon couldn't cause high pH, normal or low carbon couldn't cause
low pH)




what does the QRS complex of the EKG represent?

drug induced hypoventilation, COPD




Focus on the specific changes in blood pressure (systolic and diastolic), and the
underlying changes in resistance and cardiac output that produce these changes

(both increase blood pressure)
Dynamic exercise produces high cardiac output but the resistance will not
be as high due to vasodilation in active muscles.

Give this one a try later!


the volume of air moved in and out of the respiratory system during resting
ventilation

-Many of the bodies thermoreceptors are in the skin, altering temperatures
there can convince the body that it is under thermal stress and will induce a
homeostatic response.




Anti Rh antiserum is labeled as what in this laboratory?


Give this one a try later!


anti D




when we have an expanded fluid volume...


Give this one a try later!


ANF increases sodium and water secretion, inhibits thirst, and inhibits renin,
aldosterone, and ADH secretion




describe the metabolic state of an individual in terms of RER, anaerobic threshold aka
anaerobic metabolism, V02-Max, anaerobic metabolism, and aerobic metabolism
during the following states: rest, walking, light exercise, sprint
