15 - The Lymphatic and Immune System Flashcards
(46 cards)
A substance that can cause a specific immune response and then reacts with the products of the response.
Antigen
A protein molecule produced by B cells.
Antibody
Nodes around the axilary (armpit) area that receive lymph drainage from the upper arm and the scapular and pectoral regions; they drain into the subclavian trunk.
Axilary lymph nodes
A type of lymphocyte that specializes in producing antibodies.
B cell
A sac on the inferior portion of the thoracic duct that holds chyle, a milky yellow fluid that drains from the intestines.
Cisterns chyli
An immune defense system of plasma proteins that destroy microbes.
Complement system
A protein released by cells that affects cell-to-cell communication and interactions.
Cytokines
One of several types of antibodies; a protein derived from blood that has been infected with a pathogen; antibodies are created, isolated, and injected into the human body to cause short-term immunity.
Gamma globulin
One of several small nodes deep to the tensor fascia lata that receive lymph drainage from the deep structures of the lower limbs.
Inguinal lymph node
A natural cytokine secreted by the body to keep viruses from infecting cells and replicating.
Interferon
One of the lymphatic vessels that transports a milky fluid (chyle) through the small intestine and the mesenteric glands to the thoracic ducts.
Lacteal
One of a chain of lymph nodes located around the inferior vena cava.
Lumbar lymph node
The beginning of a lymphatic vessel.
Lymph capillary
A tube that allows the passage of lymph from one place to another.
Lymph duct
A bean-sized organ located throughout the body.
Lymph node
A facial lymph node that is located at the point where the facial artery crosses the mandible.
Mandibular lymph node
A cell that that remains after the body mounts an immune response to an antigen and is capable of an immediate response to the reappearance of the same antigens.
Memory cells
A node located in and around the abdominal membranes.
Mesenteric lymph nodes
A large, oval-shaped mass of lymphatic tissue located in the wall of the pharynx at the back of the throat; the structure commonly referred to as the tonsils.
Palatine tonsils
Cell capable of “swallowing up” other cells (harmful ones) and even digesting them.
Phagocyte
A group of small lymphatic nodules located on the back and roof of the nasopharynx.
Pharyngeal tonsils
Two groups of nodes located around the back of the knee that drain the skin of the posterior leg; deep structures of the leg, and side of the foot.
Popliteal lymph nodes
A type of cell derived from the thymus that helps coordinate immune system functions through the secretion of hormones.
T cell
Specialized T cells that destroy infected or other diseased cells, including cancer cells; the most significant component of the cellular immune response.
T-cytotoxic cells
