Advanced Pathophysiology NURS 5315 Test 2

Advanced Pathophysiology NURS 5315 Test 2 natural immunity immunity that we are born with Natural Immunity barriers skin, mucus membrane, natural killer cells, protein What protiens are associated with our natural immunity barriers? Cytokines and complements Phagocytic cells Neutrophils, macrophages, dendritic cells Neutraphils Associated with acute inflammation macrophages cells formed from monocytes that leave the blood stream Dendritic cells engulfs antigens in the epithelial, gi trac, and respiratory tract Antigen Presenting cells (APC) dendritic cells, macrophages, B cells What do the antigen presenting cells do? engulf antigens and present fragments of antigens to T cells for recognition Complement cells form membrane attack complex and are able to lyse pathogen membranes acquired immunity Immunity that is present only after exposure and is specific. Which immunity type is vaccinations based on? acquired immunity passive aquired immunity antibodies are given to a recipient to provide immunity What type of immunity is used to treat rabies, tetanus, hepatitis, and snake bites? Passive immunity how long does passive immunity last? 2 weeks humoral immunity B cells produce antibodies after exposure to specific antigens; type of adaptive immunity What type of immunity takes care of viral infections, toxin induced disease, and disease caused by pneumococci, meningococci, haemophilus? Humoral Immunity cell-mediated immunity T- Cells What does cell mediated immunity help protect against? cancer, fungus, parasites, tumors, is responsible for organ transplant rejection What organs are involved in the immune system response? bone marrow, thymus, spleen, lymph nodes, tonsils, peyer patches Bone marrow responsible for production of immune cells & maturation of B cells Thymus site where t cells differentiate, mature and select. spleen lymphoid organ; red pulp is where RBCs are stored and turned over. White pulp is where immune cells interact What type of infection is a person with their spleen affected more suspectable to? streptococcal bacteria T cell differentiation cells express antigens on cell membrane called "cluster of differentiation" or CD CD4 cells are also known as T helper cells
