Question

question 5
which statement best describes the relationship between the amount of blood in a region of the body and the blood pressure in that region?

• the more blood in a region of the body, the higher the blood pressure.
• the more blood in a region of the body, the lower the blood pressure.
• there is no relationship between the amount of blood in a region of the body and blood pressure.

question 6
if the gravity in the sanctuary rose above the typical gravitational force on phygaris, xors cranial blood pressure would be ___ her cranial blood pressure under the typical gravitational force on phygaris.

• similar to
• less than
• greater than

Explanation:

Analyze blood volume and regional blood pressure

Using the Fluid Redistribution and Cardiovascular Adaptation knowledge points

• An increase in the volume (amount) of blood within a specific vascular region increases the physical force exerted against the vessel walls.
• Therefore, more blood in a region directly leads to higher blood pressure in that region.

Analyze the effect of increased gravity on cranial blood pressure

Using the Gravitational Physiology and Hydrostatic Pressure Gradient knowledge points

• Gravity pulls blood downward toward the lower extremities of the body.
• An increase in gravitational force enhances this downward pull, causing more blood to pool in the lower body and reducing the amount of blood in the upper body (head/cranium).
• With less blood in the cranial region under higher gravity, the cranial blood pressure decreases.
• Thus, under higher gravity, cranial blood pressure is less than under typical gravity.

Answer:

Question 5

• The more blood in a region of the body, the higher the blood pressure. (Correct answer)
• The more blood in a region of the body, the lower the blood pressure.
• There is no relationship between the amount of blood in a region of the body and blood pressure.
