Textbook Question
Chapter 18, Problem 3AYKA

The physiological significance and the
reason one sees active hyperemia to the
skeletal and cardiac muscles and face skin
color to change during exercise includes
which of the following? (Mark all that
apply)
O Contracting muscles consume large
amounts of oxygen to replinish ATP
hydrolyzed during contraction
Blood flow and oxygen delivery must
increase to support metabolism
O Rising core temperatures induced by
metabolism increases blood flow to
dissipate heat changing skin color.
O Contracting muscles consume small
amounts of oxygen to replinish ATP
hydrolyzed during contraction
O Blood flow and oxygen delivery is
maintained at normal levels to support
metabolism
O Redistribution of blood flow to contracting
skeletal muscles and helps maintains blood
pressure.
Predict the effect of each of the following conditions on blood flow:(a) vasoconstriction of blood vessels in the skin in response to coldexposure, (b) vasodilation of blood vessels in the skin in response toelevated body temperature, and (c) erythrocytosis, which results in agreatly increased hematocrit.
For each of the following situations, describe the anticipated effect on blood pressure and the physiological basis of the response: (1) a high salt diet, (2) a blow on the head that damages the vasomotor center, (3) an attack by a stalker, and (4) a hypothalamic tumor resulting in excess ADH production.

- Newer clinical guidelines suggest using a cut-point value of 120 mmHg for systolic blood pressure to identify a person as being hypertensive. However, some clinicians and researchers have suggested increasing the cut-point value for systolic blood pressure to 130 mmHg to identify hypertension (i.e., those with systolic blood pressure of 130 mmHg and above would be positive for hypertension). If the cut-point value for identifying a person as hypertensive was increased from 120 mmHg to 130 mmHg, which of the following may occur? A. The sensitivity of the new cut-point value would increase. B. The specificity of the new cut-point value would increase. C. Both the sensitivity and specificity of the new cut-point value would increase. D. There would be no change to the sensitivity or specificity of the new cut-point value.arrow_forwardA.
