Verified step by step guidance1
Understand the function of lymphatic vessels: Lymphatic vessels are part of the lymphatic system, which is responsible for transporting lymph, a fluid containing white blood cells, throughout the body.
Identify the key features of lymphatic vessels: Unlike blood vessels, lymphatic vessels do not transport blood. They are involved in the removal of interstitial fluid from tissues and its return to the bloodstream.
Recognize the structural characteristics of lymphatic vessels: Lymphatic vessels have valves that ensure the unidirectional flow of lymph, preventing its backflow.
Differentiate between the lymphatic and cardiovascular systems: The lymphatic system is distinct from the cardiovascular system, although they are interconnected. The lymphatic system does not directly participate in oxygen exchange.
Evaluate the statements: Based on the understanding of lymphatic vessels, identify the correct statement: 'Lymphatic vessels have valves to prevent the backflow of lymph.'
