Martin Kaylee Lymphatic and Immune System Period 1
anatomy of the lymphatic system
t cells are killer cells
lymphatic vessels and tissues make up lymphatic system
lymph nodes clean debris and check for bacteria.
B cells produce daughter cells that release antibodies.
major functions of lymphatic and immune system
helps defend against pathogens
lymphatic cappilaries absorb the building blocks of fat-glycerol and fatty acids.
produces, maintains,and distribute lymphocytes
absorbs excess tissue fluid and returns it to the bloodstreams.
innate/natural immune defenses and adaptive/acquired defenses
adaptive:The third line of defense and takes more time than an innate response
Innate: - responds in minutes to protect body using two lines of defense. the first is the first line of defense which is external body membrane and intact skin. The second line of defense is when the first line fails.
humoral vs cellular response
Cellular response:protects the body from virus infection and cancer, and it is carried out by t cells
humoral:antibodies produced by B cells cause the destruction of extracellular microorganisms and prevent the spread of intracellular infections
antigens and antibodies
antigen: - Attacked by the body's antibodies - toxin-change shape so antibody won't notice them
antibody:-helps immune system-police body- recognizes foreign cells-attack antigens
disorders of the immune system
Cushing's Syndrome:condition caused by excessive corticosteroid secretion by the adrenal glands
Cushingoid Syndrome: condition caused by overdosage with corticosteroid medication
