WhatZis the function of the lymphaticZsystem? (4) CORRECT ANSWER
drain interstitial fluid, transport digested fat to blood, develop immunities, produce lymphocytes
Where isZthe lymph drained eventually? CORRECT ANSWER
Eventually the vessels empty into lymphatic trunks (also known asZcollectingZvessels) -
and these eventually converge to form the right lymphatic duct and the thoracic duct.
What is humoral immunity? CORRECT ANSWER antibody-
mediated immune response, B lymphocytes produce antibodies, fight circulating bacteria, and become pl
asma cellsZwhen they enter tissues
What is cellular Immunity? CORRECT ANSWER cell-
mediated immunity, T lymphocytes come from thymus glands, fightZintracellular viruses, fungi, parasites,
cancer
What is an antigen and an example? CORRECT ANSWER foreign protein in our body ex: snake
venom
What is the function of B cells? CORRECT ANSWER
lymphocytes found in the lymph nodes, spleen, and other lymphoid tissue where they replicate, induced
by antigen-binding activities.
What is the function of plasma cells? CORRECT ANSWER
formed by replicating B cells that enter tissue and produce huge numbers of the same antibody or immun
oglobulin
What is the function of macrophages? CORRECT ANSWER
engulf and digest antigens. They then present parts of these antigens in their cell membranes for recognit
ion by T cells. This antigen presentation function is crucial for normal T-cell responses
