The document summarizes the lymphatic system and body defenses. It describes the two main parts of the lymphatic system as lymphatic vessels and lymphoid tissues/organs. The lymphatic system functions to transport fluids back to blood, play essential roles in body defense and resistance to disease, and absorb digested fat. It also details the nonspecific and specific defense systems, including barriers, cells, chemicals, and the immune system.

36. Interferons are a family species-specific proteins synthesized by eukaryotic cells in response to viruses and a variety of natural and synthetic stimuli. There are several different interferons commonly used as therapeutics, termed alpha, beta, and gamma. These peptides are used to treat hairy cell leukemia, AIDS-related Kaposi's sarcoma, laryngeal papillomatosis, genital warts, and chronic granulomatous disease. Side effects include black tarry stools, blood in the urine, confusion, and loss of balance.
