1
The systolic blood pressure when the volunteer was standing was:
A)about 20 mm Hg.
B)about 50 mm Hg.
C)about 86 mm Hg.
D)about 116 mm Hg.
2
The systolic blood pressure when the volunteer was lying down was:
A)about 20 mm Hg.
B)about 50 mm Hg.
C)about 86 mm Hg.
D)about 116 mm Hg.
3
Imagine a fountain in a pond. If you measured the force pushing the water against gravity, the value for water pressure at the base of the fountain would be:
A)greater than the pressure at the top of the fountain.
B)the same as the pressure at the top of the fountain.
C)less than the pressure at the top of the fountain.
4
If the pressure of a fluid declines as it flows against gravity, then in a standing person the pressure of the blood at the heart would be:
A)less than the blood pressure in the head.
B)about the same as the blood pressure in the head.
C)greater than the blood pressure in the head.
5
Baroreceptors measure blood pressure in the carotid arteries. What organ is supplied by the carotid arteries?
A)The heart.
B)The brain.
C)The kidney.
D)The arms.
6
In a standing person, since blood travels against gravity from the heart to the brain, the blood pressure will:
A)decrease as it travels to the brain.
B)remain about the same as it travels to the brain.
C)increase as it travels to the brain.
7
In a person who is lying down, the brain is:
A)above the heart.
B)at about the same level of the heart.
C)below the heart.
8
If the heart and brain are at the same level in an individual who is lying down, the blood pressure in the heart will be:
A)less than the blood pressure in the head.
B)about the same as the blood pressure in the head.
C)greater than the blood pressure in the head.
9
If the pressure of the blood in the brain must stay within defined limits, what happens to the blood pressure at the heart if the person goes from a standing to a lying position?
A)The blood pressure created by the heart will decrease.
B)The blood pressure created by the heart will remain the same.
C)The blood pressure created by the heart will increase.
10
Blood pressure is decreased by activity in the:
A)voluntary nervous system.
B)sympathetic nervous system.
C)parasympathetic nervous system.
D)endocrine system.
