Immune System

QuestionAnswer
What is the function of the Immune System ? Protects body from pathological bacteria, foreign tissue cells, and cancerous cells. Made up of defensive cells and molecules. It collects and filters excess tissue fluid before returning it to venous circulation
What is a lymph? Fluid in the tissue spaces that carries protein molecules and other substances back to the blood.
What is Lymphatic Vessel? Permit only one-way movement of lymph.
Lymph nodes Filter the lymphatic fluid before it is returned to the bloodstream. Located along the lymphatic vessels. Lymph nodes and other lymphoid organs have functions that include defense and white blood cell (WBC) formation. Structure that consist of many small nodules that filter the lymphatic fluid and fight infection.
Thymus Lymphoid tissue organ located in mediastinum Total weight of about 35 to 40 g: A little more than an ounce. Plays a vital and central role in immunity. Produces T lymphocytes, or T cells.
Tonsils Composed of three masses of lymphoid tissue around the openings of the mouth and throat.
Spleen Largest lymphoid organ in body Located in upper left quadrant of abdomen. Often injured by trauma to abdomen. Surgical removal called splenectomy. Functions include phagocytosis of bacteria and old red blood cells (RBCs); acts as a blood reservoir. Splenomegaly: Enlargement of the spleen
Immunity An infection resistance type caused by the bodies immune response after exposure to antigen or vaccine administration.
Innate Immunity , Natural Immunity Also known as nonspecific immunity. Recognizes a variety of nonself cells and particles. Rapid response. Tears and mucus: Wash eyes and trap and kill bacteria
Adaptive immunity Also called specific immunity because of ability of body to recognize, respond to, and remember harmful substances or bacteria. Inherited or inborn immunity: Inherited immunity to certain diseases from time of birth.
Acquired Immunity Natural immunity: Exposure to causative agent is not deliberate. Active: Active disease produces immunity Passive: Immunity passes from mother to fetus through placenta or from mother to child through mother’s milk
Artificial Immunity Exposure to causative agent is deliberate. Active: Vaccination results in activation of immune system. Passive: Protective material developed in another individual’s immune system and given to previously nonimmune individual
Antigen A substance that prompts antibody production , resulting in an immune response.
Antibody Protein compounds with specific combining sites. Combining sites attach antibodies to specific antigens (foreign proteins), forming an antigen-antibody complex: Called humoral, or antibody-mediated, immunity. Fit a specific antigen because the shape of the antigen occupies a unique site on the antibody.
Immunization The act of conferring immunity , such as vaccination.
Leukocyte White blood cell ( WBC )
Phagocytes A cell of the immune system that engulfs cells , debris and antigens.
Immune deficiency Abnormal condition in which tissues exhibit swelling due to excessive lymph.
B cell Produce humoral Immunity
Anaphylactic shock Serious life-threatening allergic reaction , example is bee sting
Allergy Hypersensitivity
Lymphedema Abnormal condition in which tissues exhibit swelling due to excessive lymph.
Tonsillitis Inflammation of tonsils .
Isoimmunity Excessive reaction to antigens from another human being, such as between mother and unborn baby.
Lymphoma Cancer of the lympathic system .
Hodgkin Disease Principal category of lymphoma.
What are the most numerous cells of the immune system ? Neutrophils
Two types of malignant lymphomas ? Hodgkin disease and non-Hodgkin lymphoma.
What are the characteristic signs of the inflammatory response? Heat, redness, pain, and swelling.
Superficial vessels These are type of lymphatic vessels arise in subcutaneous tissue and accompany venous flow.
