Circulatory System/Diffusion Quiz

Which is true of the circulatory system?

• Doesn't interact with other body systems

• involved breaking down food into smaller pieces

• Helps deliver needed materials to the cells of your body

• Releases waste into the digestive system

What is not true of your blood vessels?

• The veins are the site of material exchange with the cells

• Blood vessels are found throughout your body

• Arteries carry blood away from the heart

• Capillaries are the smallest blood vessels

Why might glucose (a simple sugar) levels decrease in the blood after eating?

• Glucose is absorbed into the cells from the digestive system

• Glucose is absorbed into the cells from the blood

• Glucose is absorbed into the blood from the digestive system

• Glucose is absorbed into the heart making is beat faster

Which state(s) of matter does diffusion occur in?

• Liquid

• Freezing

• Solid

• All of the choices

What best describes diffusion

• Particles moving from an area of higher concentration to an area of lower concentration

• Particles moving from an area of equal concentration to an area of lower concentration

• Particles moving from an area of lower concentration to an area of higher concentration

• Particles moving from an area on no concentration to an area of equal concentration

When we talk about diffusion, does the word "concentration" mean?

• Focusing intensely on a problem

• How much of something you find in a certain area.

• The speed particles are moving as they are heated

• The type of substance that is added to water

Which is true of osmosis?

• Is it the diffusion of food coloring within a beaker of water

• Only occurs in circulatory cells

• Can change the size of a cell

• Is the diffusion of oxygen into a cell

Suppose you place several plant cells in pure water. Which of the following would occur?

• Water would move into the cells because of a higher concentration of salt outside of the cells

• Water would move out of the cells because there is a lower concentration of water in the cells

• Water would move into the cells because there is a lower concentration of water in the cells

• Water would move out of the cells because there is a lower concentration of water outside of the cells

Which describes the flow of water molecules in this picture. The square represents a cell

• Water will flow out of the cell at a faster rate than into the cell

• Water will flow into the cell at a faster rate than out of the cell

• Water will flow in and out of the cell at the same rate.
