70.If the blood plt is 7.46 and the blood sodium level is on the low side, which of the following is mog likely to occur? a. Aldosterone will be released and the tubules will reabsorb hydrogen ions b. Aldosterone release will be inhibited and rennin will be produced c. Hydrogen ions will be secreted and ADH will be produced d. ADH production will be inhibited 71. The sympathetic branch of the autonomic nervous system causes bronchioconstriction a. True b. false 72. During an acute asthma attack a. Bronchioles dilate due to the parasympathetic stimulation b. Airway resistance decreases c. Smooth muscles around bronchioles constrict the air conducting passageways d. There is a loss of elasticity of lung tissue 73. Respiratory distress syndrome is associated with a. Premature births b. Difficulty inflating alveoli c. Lack of surfactant d. All of the above 74. A large concentration of histamine floods the body during an acute allergy; this condition (aka anaphylaxis) can lead to death due to a. Hypotension as a result of massive vasodilation b. Inadequate gas exchange due to bronchioconstriction c. Insufficient delivery of oxygen to the tissues d. All of the above Pe 10

Explanation / Answer

71.sympathetic branch cause bronchodilatation whereas parasympathetic branch causes bronch constriction .so this is false.

73respiratory distress syndrome is a premature developemental defect.there is decrease in surfactant decrease in alveolar inflating so .optionD

72 during acute asthma attach there smmoth muscle constrictvairways ,there sis increase in airwayvresistance and parasympathetic branch cause bronchiconstriction.

So option C

74high histamine cause bronchicibstriction ,hypotension and inadequte perfusion.so option D.

111.both symoathetic and parasympathetic causes increas in blood glucose level.

112 sympathetic nervous system cause bronchodilatation.

113 parasymoathetic nervous system decrease cardiac output and also cause cinstriction of pupils.

126v.autonimic nervous system parasympathetic branch involve both cranial and spinal nerve.optionB.

127.effectors are gland and involuntary muscles these are characteristics of autonomic nervous system.so option B
