A nurse is teaching a nursing student how blood can return to the heart when pressure in the venous capillary beds is very low. Which statement by the student indicates a need for further teaching?

• "Constriction of small muscles in the venous wall increases venous pressure."
• "Negative pressure in the left atrium draws blood toward the heart."
• "Skeletal muscles relax to allow the free flow of blood."
• "Venous valves help prevent the backflow of blood." - ANSWER-c.
