Document Summary
Immunity is the body"s ability to resist damage from microorganisms: innate uses barriers and wbc to destroy foreign substances, adaptive uses antibody proteins to defend body from specific type of foreign substances. Prepares body for future encounters from same foreign substance via memory cells. Describe structure and f(x) of: tonsils, lymph nodes, spleen, thymus. Define specificity and memory as concepts of immunity. List events during inflammatory response and explain the importance. Describe lymphocytes, their origin, development, activation and proliferation. Describe primary vs. secondary response to an antigen. Describe interaction of innate, antibody-mediated and cell-mediated immunity when eliminating an antigen. Basophils: a type of wbc granulocyte, least common and is involved in inflammatory responses and forming clots. Lymphocytes: a type of wbc agranulocyte, smallest wbc that has several functions in immune responses. Lacteals: lymphatic vessels located in the walls of small intestine which absorbs lipids from the digestive tract to deposit into the venous circulation.
