STUDY GUIDE RATED A GRADE.
Describe how your body responds to an infection. - SELECTED
ANSWER 👀******** T cells produce cytokines, which stimulate B cells.
B cells produce antibodies.
Identify role of DNA changes in congenital abnormalities. - SELECTED
ANSWER 👀******** Mutations in genes or chromosomal abnormalities
How does development disrupts congenital abnormalities? -
SELECTED ANSWER 👀******** Alterations of DNA
Describes factors that disrupt homeostasis and how disruptions affect
wellbeing. - SELECTED ANSWER 👀******** (ex) Fluid and electrolyte
shifts can cause n/v or dysrhythmias.
Explain RAAS - SELECTED 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.
