The cells of the lymphatic system produce proteins known as ________, which assist in immune response regulation. Two types of these proteins are monokines and lymphokines.

Lymphatic System

A network of vessels, nodes, and organs that helps to maintain the body's fluid balance and protect it from infections by filtering and moving lymph.

Monokines

Signaling molecules primarily released by monocytes, involved in inflammatory and immune responses.

Lymphokines

Substances produced by certain cells of the immune system that affect other cells' activities, playing a role in the body's immune response.
