APHY 201 Exam 5 focused review Questions with Correct Answers
Question 1:
As container volume increases, pressure decreases (because the more volume, the more the
liquid or
Answer:
As volume decreases, pressure increases
Question 2:
Hydrostatic pressure: the pressure of liquid pushing outward against the walls of a container.
Answer:
Describe the factors that determine pressure of a liquid
Question 3:
Velocity of flow: How fast a molecule flows from one point to another. Velocity is greater in
smaller
Answer:
Flow rate: how many molecules are being received at one time
Question 4:
In the body, constriction and dilation are used to adjust flow rate and velocity to compensate
for local or
Answer:
Describe how changes in diameter of a tube affect flow rate and velocity
Question 5:
Resistance: the opposition to flow of a gas or liquid, created by friction between the walls of a
container
Answer:
Define resistance to flow, and describe how it is created.
Question 6:
Plaque buildup or cholesterol or platelets, change in blood glucose or pH in the veins/arteries
can
Answer:
and the molecules of a gas or liquid.
, Question 7:
State the three factors that affect flow through tubes, and state how each changes
resistanceTube radius: as tube diameter decreases, the resistance to flow increases.Tube
length: As tube length increases, the resistance to flow increasesGas or fluid velocity: As
velocity increases, the resistance to flow increases
