The immune system is a complex network of cells, tissues, and organs that work together to protect the body from infection.

Humoral immunity is not a type of immune response. It is a component of adaptive immunity that involves the production of antibodies.

T cells play a variety of roles in the immune system, including producing antibodies, killing infected cells, and helping B cells produce antibodies.

B cells play a crucial role in the immune system by producing antibodies, which are proteins that recognize and neutralize foreign invaders.

IgE is not a type of antibody. It is a type of immunoglobulin that is involved in allergic reactions.

Macrophages are phagocytic cells that engulf and destroy foreign invaders, such as bacteria and viruses.

Basophils are not phagocytic cells. They are a type of white blood cell that is involved in allergic reactions.

Cytokines are small proteins that are produced by immune cells to communicate with each other. They play a crucial role in regulating the immune response.

Interferon is not a type of cytokine. It is a type of protein that is produced by cells in response to viral infection.

The complement system is a group of proteins that work together to help antibodies destroy foreign invaders.

C6 is not a component of the complement system. It is a component of the coagulation cascade.

The lymphatic system is a network of vessels and nodes that drains excess fluid from tissues and returns it to the bloodstream.

The thymus is not a component of the lymphatic system. It is a primary lymphoid organ where T cells mature.

The spleen is a large organ that filters blood and removes foreign invaders, such as bacteria and viruses.

The spleen does not produce bile. Bile is produced by the liver.
