-biconcave disks (lack nucleus)
Leukocytes (WBC)
-protection and defense
-tissue repair
-some are macrophages (perform phagocytosis)

-hemostasis (ability to control bleeding)
-thrombocytopenia (low platelet count
Lymphatic system
-network of vessels that drain fluid and return to blood)
-maintains the cells (WBC); immunity
Lymphatic structures

Immune system
Protects the body against disease-causing organisms
Types of defense (immune system)
Innate; Acquired
Innate
Present at birth
Acquired
Develops throughout a lifetime with each encounter with a pathogen/foreign substance
Antibody
Protective protein produced by B lymphocytes in response to the presence of a specific foreign substance called an antigen
Antigen
Substance, recognized as harmful to the host, that stimulates formation of antibodies in an immunocompetent individual
Bite pigment
Substance derived from the breakdown of hemoglobin nd excreted by the liver
Cytokine
Chemical substance produced by certain cells that initiates, inhibits, increases, or decreases activity in other cells; chemical communication
Dendritic cell
Specialized type of monocyte that display antigens on its cell surface and presents them to components of the immune system
Natural killer (NK) cells
Specialized lymphocytes that destroy virally infected cells and tumor cells by releasing chemical that disrupt their cell membranes, causing their intercellular fluid to leak out
