Verified step by step guidance
1
Understand the role of the lymphatic system: The lymphatic system is responsible for returning interstitial fluid, which is the fluid that leaks out of the blood vessels, back into the circulatory system.
Identify the components of the lymphatic system: The lymphatic system includes lymphatic vessels, lymph nodes, and lymph. Lymphatic vessels are similar to veins and capillaries but are specifically designed to transport lymph.
Differentiate between the options: Veins and capillaries are part of the blood circulatory system, while sinusoids are specialized capillaries found in certain organs. Lymphatics are the vessels that specifically transport lymph.
Recognize the function of lymphatics: Lymphatic vessels collect interstitial fluid from tissues and transport it as lymph back to the bloodstream, usually at the subclavian veins.
Conclude with the correct answer: Based on the function of transporting interstitial fluid back into the blood, the correct vessels are the lymphatics.
