which stimulate B cells. B cells produce antibodies.
Identify role of DNA changes in congenital abnormalities. - Answer--Mutations in genes
or chromosomal abnormalities

Describes factors that disrupt homeostasis and how disruptions affect wellbeing. -
Answer--(ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias.
Explain RAAS - Answer--Renin-angiotensin-aldosterone system
1. Reduce blood flow causes kidneys to release renin
, > produce angiotensin I > converts angiotensin I to angiotensin II > vasoconstriction >
release aldosterone > kidneys conserve sodium and water > Result less water lost in
urine and blood pressure maintained.
