Exercise 1: Microscopic Anatomy of Lymphatic Structures


A. How are lymph, lymphatic vessels and lymph nodes related? a. They are related because the lymphatic system is a network of tissues and organs. It is made up mainly of lymph vessels,

Two types of lymphocyte are produced in the bone marrow before birth.

D. Distinguish between an antigen and an antibody. a. Antigens are substances that provoke an immune response. Antibodies are simply proteins that are secreted as a result of the antigen provoked immune response. In short, antigens cause the disease and antibodies cure it.

E. Why is the term “immune system” a misnomer? a. In order to be immune you must first have the foreign pathogen in your body so your immune system could create defenses for it.

Conclusion: Look up information on autoimmune diseases. What are they? Give examples and explain how they help researchers better understand the immune response. Autoimmune disorders are diseases that occur when the body produces an inappropriate immune response against its own tissues. Sometimes the immune system will cease to recognize one or more of the body’s normal constituents as self and will produce autoantibodies. These attack their own cells, tissues, and/or organs. These causes inflammation and damage and leads to autoimmune disorders. The cause of autoimmune diseases is unknown, but it appears that there is an inherited predisposition in many cases. In a few types of autoimmune disease, a virus or infection with bacteria triggers an immune response and the antibodies or T-cells attack normal cells because some part of their structure
