Untitled Flashcard Set

  • Sphygmomanometer / The scientific name of the device used to take a blood pressure reading.

  • Systolic Pressure / The pressure when the first sound of Korotkoff occurs.

  • Diastolic Pressure / The pressure when the last Korotkoff sound is heard/disappears.

  • Korotkoff sounds / Sounds produced by turbulent flow of blood through a partially compressed artery.

  • Laminar flow / Smooth, silent blood flow; typical of the brachial artery before cuff inflation.

  • Pulse Pressure Calculation / Systolic pressure minus diastolic pressure.

  • Mean Arterial Pressure (MAP) Calculation / Diastolic pressure + 1/3(pulse pressure).

  • Athlete’s Bradycardia / A resting heart rate lower than average caused by higher parasympathetic inhibition of the SA node.

  • Aerobic Capacity (VO2 max) / The maximum rate of oxygen consumption by the body.

  • Lactate Threshold / The intensity of exercise where lactic acid begins to accumulate significantly in the blood.

Blood & Leukocytes (Ex 6.1, 6.2, 6.3)

  • Hematocrit / The percentage of total blood volume occupied by red blood cells.

  • Erythropoietin / The hormone secreted by the kidneys that stimulates RBC production.

  • Bilirubin / A pigment derived from heme (minus iron); high levels cause yellowing known as jaundice.

  • Neutrophil / A polymorphonuclear phagocytic WBC with poorly staining granules; the major phagocyte.

  • Eosinophil / A leukocyte with granules that have an affinity for red stain.

  • Basophil / The rarest white blood cell.

  • Lymphocyte / An agranular WBC with a round nucleus and little cytoplasm; produces antibodies.

  • Monocyte / An agranular and phagocytic white blood cell; the largest WBC.

  • Agglutination / The clumping of red blood cells when they react with matching antibodies.

  • Universal Blood Donor / Type O negative.

  • Universal Blood Recipient / Type AB positive.

Digestive Enzymes (Ex 10.2)

  • Salivary Amylase / An enzyme that partially digests starch into maltose.

  • Pepsin / An enzyme in gastric juice that partially digests proteins.

  • Pepsin Optimal pH / Acidic environment (pH ~2) provided by HCl.

  • Bile Salts Function / Emulsification of fats to increase surface area for digestion; not an enzyme.

  • Lipase Product / Fatty acids and glycerol; fatty acids cause the pH of the solution to fall.
