lab final Flashcards
cardiac action potential
step 1: rapid depolarization
Na+ entry, closure of sodium channels
step 2 : plateau
Ca2+ entry, closure of calcium channels
step 3 : repolarization
K+ loss, closure of potassium channels
granulocytes
neutrophils eosinophils basophils
agranulocytes
monocytes and lymphocytes
neutrophils
most abundant WBC, act as phagocytes and destroy pathogens
eosinophils
attack parasites and diminish inflammation and alllergies
basophils
RAREST
monocytes
kidney shaped nuclei that attack and destroy bacteria
lymphocytes
regulate immune response and produce antibodies
blood type A
antibody B, antigen A
blood type B
antibody A, antigen B
blood type AB
antigen AB
blood type O
antibody A & B
primary lymphatic organs
red bone marrow and thymus gland
this is where lymphocytes form and mature
secondary lymphatic organs
where lymphocytes are activated and tissues filter out extracellular fluids
lymphatic system functions
fluid balance, fat absorption, houses defenses, transports O2, hormones, nutrients, removes metabolic waste, transports antibodies and lymphocytes to the blood & prevents microbe invasion
