Explanation:
Detailed explanation-1: -Most of the lymphatic vessels have valves like those in veins to keep the lymph, which can clot, flowing in the one direction (toward the heart). Lymphatic vessels drain fluid called lymph from tissues throughout the body and return the fluid to the venous system through two collecting ducts.
Detailed explanation-2: -The correct answer is A. Lymphatic vessels pass through lymph nodes. This allows the lymph to be filtered as it travels through the lymph nodes. The filtration system in the lymph nodes removes antibodies and pathogens and stimulates the immune responses as needed.
