Major functions of the
Lymphatic & Immune systems;
the primary function of the immune system is to protect the body from foreign bodies that make it inside the body.
The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body and get rid of bodily watse
Anatomy of the lymphatic system
Collecting lymphatic vessels
Innate defenses and Adaptive immune defenses;
the body’s built-in specific defensive system that stalks and eliminates with nearly equal precision almost any type of pathogen that intrudes into the body.
uses Humoral immunity and cellular immunity
the mechanical barriers that cover body surfaces and the cells and chemicals that act on the initial internal battlefronts are in place at birth, ready to ward off invading pathogens

humoral vs. cellular response;
immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides.
Cell-mediated immunity is an immune response that does not involve antibodies, but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen
antigens and 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.
Y-shaped molecules are proteins manufactured by the body that help fight against foreign substances called antigens.
