WITH COMPLETE SOLUTIONS (100 % CORRECT AND
VERIFIED) ALREADY PASSED!!
Describe how your body responds to an infection. - ...(ANSWERS)....T cells
produce cytokines, which stimulate B cells. B cells produce antibodies.
Identify role of DNA changes in congenital abnormalities. -
...(ANSWERS)....Mutations in genes or chromosomal abnormalities
How does development disrupts congenital abnormalities? -
...(ANSWERS)....Alterations of DNA
Describes factors that disrupt homeostasis and how disruptions affect wellbeing. -
...(ANSWERS)....(ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias.
Explain RAAS - ...(ANSWERS)....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.
DKA - ...(ANSWERS)....increased anion gap, decreased HCO3
How do kidneys compensate for alkalosis - ...(ANSWERS)....retain H and excrete
HCO3
