Anatomy of the lymphatic system (including vessels, nodes, MALT,
spleen and thymus);
Lymphatic System
The removal of excess fluids from body tissues. ...
Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system.
Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells).
Immune system
The major function of the immune system is to protect the host from environmental agents such as microbes or chemicals, thereby preserving the integrity of the body
Innate/natural immune defenses
Physical Barriers. such as skin, the gastrointestinal tract, the respiratory tract, the nasopharynx, cilia, eyelashes and other body hair.
Defense Mechanisms. such as secretions, mucous, bile, gastric acid, saliva, tears, and sweat.
General Immune Responses.
Adaptive/acquired immune defenses
The acquired immune system is one of the two main immunity strategies found in vertebrates (the other being the innate immune system). Acquired immunity creates immunological memory after an initial response to a specific pathogen, and leads to an enhanced response to subsequent encounters with that pathogen.

Type 1 diabetes. The immune system attacks the cells in the pancreas that make insulin. ...
Rheumatoid arthritis. This type of arthritis causes swelling and deformities of the joints. ...
Lupus. This disease that attacks body tissues, including the lungs, kidneys, and skin.
antigens
a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies.
antibodies
a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
humoral
Humoral immunity is also called antibody-mediated immunity. ... Antibodies produced by the B cells will bind to antigens, neutralizing them, or causing lysis (dissolution or destruction of cells by a lysin) or phagocytosis.
cellular response;
Cellular immunity occurs inside infected cells and is mediated by T lymphocytes.
The lymphatic system consists of lymph vessels, ducts, nodes, and other tissues. Around 2 liters of fluid leak from the cardiovascular system into body tissues every day. ... Unlike blood, the lymphatic fluid is not pumped but squeezed through the vessels when we use our muscles
