Apoptosis {Ans: A form of programmed cell death that eliminates senescent cells, DNA,, and damage or unwanted cells.}Relative Polycythemia {Ans: Due to a loss of plasma volume without a corresponding decrease in red blood cells. Occurs with water deprivation, excess use of diuretics, or GI losses Corrected by increasing the vascular fluid volume (Hydration)}Overt AIDS {Ans: Th cell count <200, or AIDS-defining illness death within 2-3 years if no treatment}Renin-Angiotensin-Aldosterone System(RAA) {Ans: 1. A reduction in arterial blood pressure stimulates the release of renin by the kidney into the blood 2. Renin catalyzes the conversion of angiotensinogen to angiotensin I in the plasma 3. Angiotensin I is converted to Angiotensin II by ACE in the lungs 4. Angiotensin II triggers the vasoconstriction of systemic arterioles 5. Angiotensin II stimulates the adrenal cortex to secrete aldosterone, which stimulates the kidney to reabsorb sodium 6. Sodium reabsorption leads to an increase in arterial blood pressure.}Conjugated bilirubin {Ans: Water-soluble}Neoplastic cells do not die off (apoptosis) to keep the number of total cells constant. {Ans: }
