Which of the following is a collection of vessels and organs that move fluid during an active immune response?

A) the vaccination complex
B) the lymphatic system
C) antigens
D) antibodies

The lymphatic system is a collection of vessels and organs, including lymph nodes, that play a crucial role in the immune response by transporting lymph, a fluid containing white blood cells and antigens, throughout the body. The lymphatic system helps to remove foreign substances and excess fluid from tissues, and also helps to activate and coordinate immune responses. The vaccination complex, antigens, and antibodies are all important components of the immune system, but they do not specifically refer to the collection of vessels and organs that move fluid during an active immune response.
