perspiration:
broad spectrum antimicrobials |
antimicrobial peptides
|
|
|
perspiration:
destroys cell walls of bacteria |
Lysozyme
|
|
|
-secreated by sebacueous glands
-keeps skin pliable -lowers pH |
Sebum- Oil
|
|
|
iron is insoluble in us and must be transported in special proteins..
|
Transferins
|
|
|
Bacteria produce these, have a strong affinity for iron, steal it from Transferins
|

|
|
|
bacteria produce these to break open RBC, release iron

|
|
Basophils
Eosinophils Neutrophils |
Granulocytes
|
|
|
Lymphocyte
Monocyte |
Agranulocytes
|
|
|
process of cells exiting blood by squeezing between the cells lining capillaries
|
Diapedesis
-eosinophils -neutrophils |
|
|
Phagocytic cells of the 2nd line of defense
|
Macrophages
|
|
|
macrophages that leave the blood via diapedesis and phagocytize throughout the body
|
Wandering macrophages
|
|
|
macrohages dont move thru the body and phagocytize within a specific organ
|
Fixed macrophages
|
|
|
stem cells in bone marrow divide to produce
Erythrocytes Platelets Leukocytes |
Hematopoesis
|
|
|
Cells capable of phagocytosis
|
Phagocytes
|
|
|
ANtibodies or other substances that bind to foreign bodies
|
Opsonins
|
|
|
mainly attack parasitic helminths (worms), by attaching to surface and secrete toxins
|
Eosinophils
|
|
|
Subclass of lymphocytes- non-specific immunity
-secrete toxins onto virally infected cells/tumors -diff body cells- have similar memb proteins |
Natural Killer Lymphocytes
(NK cells) |
|
|
Produce chemicals that kill nearby invaders
-extracellular fibers bind to/kill bacteria by immobilizing, antimicrobial peptides |
Neutrophils
|
|
|
Protein released by host cells to nonspecifically inhibit the spread of viruses
|
Interferons
-Alpha -Beta -Gamma |
|
|
Interferons produced by infected cell- protect neighboring cells by stimulating production of AVP...

-stimulate IL-1 production |
|
|
nonspecific response to tissue damage resulting from various causes
|
Inflammation
-redness -heat -swelling -pain |
|
|
