For a typical person, at what blood pressure is the first Korotkoff Sound heard? Does this correspond with SBP or DBP?
120 mmHg; SBP.

What is the name of the anastomosis that supplies the brain?
Circle of Willis (cerebral arterial circle)
100
Name the category that includes RBC, WBC, and platelets.

The left coronary artery branches into which two branches?
Anterior Interventricular Branch/Left Anterior Descending Artery (LAD) and Circumflex Branch
200
What is the equation for calculating mean arterial pressure (MAP)? You can use DBP, SBP, and/or PP in your answer.
MAP = DBP + (SBP-DBP)/3 = DBP + PP/3

Which structure in the FETAL circulation bypasses the liver? 
Ductus venosus

Epicardium -> Myocardium (thickest) -> Endocardium
300
Is a blood pressure reading of 95/65 considered hypotensive, normal, or hypertensive?
Normal (<120 mmHg, <80mmHg). Hypotensive is <90/<60 and hypertensive is >140/>90.

List the following WBC from most common to least common in the body: Monocytes, Lymphocytes, Eosinophils, Neutrophils, Basophils.
“Never Let Monkeys Eat Bananas” Neutrophils>Lymphocytes> Monocytes>Eosinophils>Basophils.

Ductus Arteriosus

If SV = 0.05L (50 mL), BP = 100 mmHg, HR = 90 beats/min, and the patient is wearing sunglasses, calculate the CO.
CO = HR x SV = (90 beats/min) x 0.05L (50 mL) = 4.5L/min or 4500 mL/min
