1. Describe how your body responds to an infection.: T cells

produce cy-tokines, which stimulate B cells. B cells produce antibodies.

2. Identify role of DNA changes in congenital abnormalities.:

Mutations ingenes or chromosomal abnormalities

3. How does development disrupts congenital abnormalities?:

Alterations ofDNA

4. Describes factors that disrupt homeostasis and how

disruptions affectwellbeing.: (ex) Fluid and electrolyte shifts can cause

n/v or dysrhythmias.

5. Explain RAAS: Renin-angiotensin-aldosterone system

1. Reduce blood flow causes kidneys to release renin

> produce angiotensin I > converts angiotensin I to angiotensin II > vasoconstric- tion

> release aldosterone > kidneys conserve sodium and water > Result less water lost

in urine and blood pressure maintained.

6. DKA: increased anion gap, decreased HCO3

7. How do kidneys compensate for alkalosis: retain H and excrete HCO3

8. Untreated acidosis leads to an increase in which electrolyte?: Potassium

9. West Nile Virus: Transmitted through the bite of an infected mosquito. Severe

signs and symptoms; high fever, headache and stiff neck

10. Lyme disease: Tick-borne disease caused by the spirochete Borrelia burgdorferi.
