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