IMMUNE SYSTEM CH. 24
CHAPTER 24
| Question | Answer |
|---|---|
| IMMUNE SYSTEM IN HUMANS CONSIST OF: | 1. NONSPECIFIC DEFENSE RESPONSES (PHAGOCYTOSIS)2. SPECIFIC IMMUNE RESPONSES (HUMORAL & CELL MEDIATED IMMUNITY) |
| IMMUNITY | THE BODY'S ABILITY TO RECOGNIZE AND DESTROY SPECIFIC PATHOGENS AND TO PREVENT INFECTIOUS DISEASE |
| WHEN AN IMMUNE SYSTEM BECOMES OVERACTIVE | CAN CAUSE POSSIBLE ALLERGIES & AUTOIMMUNE DISORDERS |
| BODY'S IMMUNE SYSTEM INCLUDES: | 1. BONE MARROW2. LYMPHOID ORGANS3. MONONUCLEAR PHAGOCYTE SYSTEM (RETICULOENDOTHELIAL SYSTEM) |
| PRIMARY FUNCTIONS OF THE IMMUNE SYSTEM: | 1.DEFENSE2.HOMEOSTATIS3.SURVELLLANCE |
| CELLS IN BONE MARROW CAN DEVELOP INTO ANY 3 TYPES OF BLOOD CELLS: | 1. ERYTHROCYTES (RBC)2. LEUKOCYTES (WBC)3. THROMBOCYTES (PLATELETS) |
| WHITE BLOOD CELLS ARE CALLED: | LEUKOCYTES |
| RED BLOOD CELLS ARE CALLED | ERYTHROCYTES |
| PLATELETS ARE CALLED | TRHOMBOCYTES |
| WHAT DOES THE WHITE BLOOD CELLS DO? | DEFENDS THE BODY AGAINST DISEASE ORGANISMS, TOXIN, IRRITANTS |
| WHAT ARE THE TYPES OF WHITE BLOOD CELLS? | 1. GRANULAR (NUTORPHILES, BASOPHILS, EOSINOPHILS)2. AGRANULAR (WITHOUT) (MONOCYTES, LYMPHOCYTES) |
| WHAT IS THE CORNERSTONE OF THE IMMUNE SYSTEM? | LYMPHOCYTES (THEY RECOGNIZE FOREIGN SUBSTANCES IN THE BODY) |
| T-CELLS | 1. PROTECT AGAINST VIRAL INFECTION 2. CAN DETECT & DESTROY SOME CANCER CELLS |
| B-CELLS | DEVELOP INTO CELLS THAT PRODUCE ANTIBODIES (PLASMA CELLS) |
| FUNCTIONS OF THE IMMUNE SYSTEM: (DEFENSE) | -RESIST INVASION-ATTACK SOME PATHOGENS DIRECTLY-ATTACK FOREIGN ANTIGENS-HELPS BODY TO FIGHT CANCER CELLS-PRODUCE ANTIBODIES & IMMUNOGLOBULINS-PRODUCES INFLAMMATORY RESPONSE-PRODUCES MEMORY CELLS |
| FUNCTIONS OF THE IMMUNE SYSTEM: (HOMEOSTATIS) | -DIGEST & REMOVES DAMAGED CELLULAR SUBSTANCES-KILLS DISEASED CELLS |
| FUNCTIONS OF THE IMMUNE SYSTEM: (SURVEILLANCE) | -RECOGNIZE & DESTROYS CELLULAR MUTATIONS-RECOGNIZES & DESTROYS FOREIGN CELLS-MONITORS FOR PRESENCE OF ANTIGENS |
| WHAT ARE THE 2 TYPES OF LYMPHOCYTES? | 1. T-CELLS2. B-CELLS |
| STEM CELLS IN THE BONE MARROW ARE RESPONSIBLE FOR PURDUCTION & MATURATION OF: | B-CELLS |
| WHAT CELLS ENLARGE & MULTIPLY RAPIDLY TO PRODUCE CLONE COLONIES WHICH BECOME PLASMA CELLS WHICH PRODUCE SPECIFIC ANTIBODIES | B-CELLS |
| ANTIBODIES PROVIDE THE FORM OF IMMUNITY CALLED | HUMORAL IMMUNITY |
| HUMORAL= | BODY FLUID |
| HUMORAL IMMUNITY PROCESS: | MACROPHAGES (LARGE CELLS) ENGULF & DESTROY ANTIGENS AFTER ANTIBODIES HAVE IDENTIFIED THEM FOR DESTRUCTION |
| IMMUNOLOGIC MEMORY | MAKES A PERSON IMMUNE TO REINFECTION WITH A DISESE AFTER H/S HAS HAD IT.(BUT NOT TRUE FOR ALL DISEASES) |
| B LYMPHOCYTES ARE FOUND WHERE: | PERDOMINANTLY IN THE LYMPHOOID TISSUE SUCH AS THE "SPLEEN" |
| ANTIGENS (Ag) | ANY FOREIGN SUBSTANCE OR MOLECULE ENTERING THE BODY THAT STIMULATES AN IMMUNE RESPONSE(THE ACTIVITY OF B OR T CELLS) |
| ANTIBODIES (Ab) | PROTEIN SUBSTANCE THAT THE BODY PRODUCES IN RESPONSE TO AN ANTIGEN |
| B LYMPHOCYTES ARE RESPONSIBLE FOR: | ANTIBODY PRODUCTION |
| ANTIBODIES CALLED "GAMMA GLOBULINS" OR "IMMUNOGLOBULINS" ARE CONTAINED IN WHAT? | A POPRTION OF BLODD CALLED "GAMMA GLOBULIN FRACTION" |
| (ANTIBODIES)5 BASIC GROUPS OF IMMUNOGLOBULINS: | 1. IgM2. IgG3. IgA4. IgE5 IgD |
| FUNTIONS OF IgM: | -ABUNDANT IN BLOOD-NOT USUALLY PRESENT IN ORGANS AND TISSUE-NOT TRANSFERRED ACROSS THE PLACENTA |
| FUNCTIONS OF IgG: | -PROTECTS FETUS BEFORE BIRTH-ONLY ANTIBODY -TRANSFERRED FROM THE MOTHER TO FETUS-MOST COMMON AND ABUNDANT-MAIN COMPONENT OF |
