Humoral immunity is the component of the adaptive immune response that is caused by B cells, antibodies, and type 1 helper T cells (Th1).

Correct Answer: False
It is true that Humoral immunity is a component of adaptive immune response and is caused by B cells and antibodies but it is mediated by Type 2 helper T cells (Th2) and NOT type 1 helper T cells (Th1). This type of immunity is also mediated by eosinophils ad mast cells to a lesser extent. Its name comes from the idea that blood is one of the humors of the body, since antibodies provide passive or active immunity through circulation in the bloodstream.
