Final answer:
Antigens derived from infections in connective tissues are carried by lymphatics to the nearest lymph node, which filters the antigens. Lymph nodes remove debris and pathogens from the lymph and are connected to lymphatic vessels.
Step-by-step explanation:
Antigens derived from infections originating in connective tissues are carried by lymphatics to the nearest lymph node. Lymph nodes function to remove debris and pathogens from the lymph. They are connected to lymphatic vessels, which transport lymph throughout the body. As lymph drains from tissues, it gathers antigens, which are then filtered through lymph nodes before the lymph is returned to circulation.
