functions of endocrine
heart rate and blood pressure metabolism blood glucose control water balance reproductive functions control uterine contractions
ligand
chemical signal
intracellular signals
travel between the same cell
intercellular signals
carry outside to another cell
neuromodulators and neurotransmitters
signals are secreted by nerve cells, mainly work in nervous system
pheromones

agranulocytes
attack pathogens w/o granules
macrophages
eat pathogens and alert other wbcs
helpter t cells
release chemicals to activate killer t
killer t cells
find infected cells and release enzymes to poke holes
b cells
tag pathogens floating around in blood
apoptosis
programmed cell death
adaptive immunity
acquire through lifetime
innate
born w./ it,
-skin, tears
natural passive immunity
mom passes antibodies to her child through milk
natural active immunity
become ill and develop antibodies
artificial active immunity
vaccine, longterm
artificial passive immunity
