• Veins

• Capillaries

• Nerves

Why is it important for the circulatory system to have three different types of blood vessels?

• They all carry oxygen only.

• They all remove waste only.

• They are all the same in structure and function.

Which type of blood vessel carries blood away from the heart?

• Arteries

• Veins

• Capillaries

• Venules

What is the main function of capillaries in the circulatory system?

• Carry blood away from the heart

• Exchange gases with surrounding tissues

• Return blood to the heart

• Store nutrients

Arrange the following blood vessels in the order that blood flows from the heart to the tissues: Arteries, Capillaries, Arterioles.

• Arteries → Arterioles → Capillaries

• Capillaries → Arteries → Arterioles

• Arterioles → Capillaries → Arteries

• Arteries → Capillaries → Arterioles

Why is the branching structure of blood vessels compared to a tree?

• Because blood vessels are made of wood

• Because blood vessels branch out into smaller vessels like tree branches

• Because blood vessels grow leaves

What process occurs in the capillaries according to the diagram?

• Blood is pumped out of the heart

• Blood exchanges gases and nutrients with tissues

• Blood is stored for later use

• Blood is filtered by the kidneys

What is the function of venules in the circulatory system?

• They deliver oxygen directly to cells.

• They collect blood from capillaries and transport it to veins.

• They pump blood out of the heart.

• They filter waste from the blood.

After capillaries exchange gases with body cells, into which type of blood vessel is the blood collected next?

• Arteries

• Veins

• Venules

• Arterioles

Which blood vessels return blood to the heart after it has passed through the capillaries and venules?

• Arteries

• Veins
