Use this revision quiz to check your understanding of the structure and function of arteries, capillaries, and veins, and how each is adapted for its job in the circulatory system.
Which type of blood vessel carries blood away from the heart at high pressure?
Which vessel feature is most important for keeping arterial blood pressure high?
Which TWO structural features help arteries withstand and maintain high pressure?
Veins carry blood towards the heart at low pressure.
Why do veins have valves?
Which blood vessel has walls that are typically one cell thick, allowing a short diffusion distance?
What is the main function of capillaries?
Complete the statements using the correct vessel type. 1) carry blood away from the heart. 2) are the main site of exchange of materials. 3) carry blood towards the heart.
Veins
Capillaries
Alveoli
Arteries
Match each blood vessel type to the correct description.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Vein | arrow_right_alt | Thick wall, small lumen, high pressure |
Artery | arrow_right_alt | One cell thick for diffusion |
Capillary | arrow_right_alt | Valves; carries blood to heart |
In a capillary bed, which TWO changes help substances exchange more easily between blood and tissues?
Diffusion in capillaries usually moves substances from a region of ____ concentration to ____ concentration.
For each vessel type, select the features that apply.
Valves present | High pressure | One-cell-thick wall | Large lumen | |
|---|---|---|---|---|

Veins |
Match each blood vessel type to its key function.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Capillaries | arrow_right_alt | Carry blood away from the heart |
Veins | arrow_right_alt | Exchange substances with tissues |
Arteries | arrow_right_alt | Carry blood toward the heart |
Veins | arrow_right_alt | Contain valves to prevent backflow |
Sort each feature into the correct blood vessel type.

Small lumen
One cell thick wall
Thick muscle walls
Permeable walls
Valves present
Elastic fibers for recoil
