How does blood flow through the heart Superior vena cava to inferior vena cave. Blood then enters the right atrium and
chambers/valves? passes through the tricuspid valve to the right ventricle. The right ventricle
pumps the blood to the lungs through the pulmonary valve to the pulmonary
arteries where it becomes oxygenated. The oxygenated blood is brought back
to the heart by the pulmonary veins which enter the left atrium. From the left
atrium blood flows through the bicuspid (mitral) valve into the left ventricle.
Which coronary arteries provide blood to which part of a. ) Left coronary artery
the heart? i.) Left anterior descending artery:widow maker
LV and RV, intraventricular septum
ii. ) Circumflex: LA and left lateral wall of LV.
b. ) Right coronary artery
RV, intraventricular sulcus and small vessels of the RV and LV
What factors contribute to blood flow in a vessel? Pressure difference between two ends of a vessel
Resistance: r/t diameter of a vessel
Viscosity (n) of the blood
Length (l) of the vessel

What does QP: QS mean and what factors alter a Q=blood flow
normal ratio? QP= blood flow to the lungs (pulmonary) : QS= blood flow to the body
(systemic)
i ) Vascular resistance =measures in woods units
ii) Pulmonary vascular resistance (PVR)
1. ) <8 weeks of age: 8-10 woods units/m2
2. ) >8 weeks of age: 1-3 woods units/m2
iii) Systemic vascular resistance
1. ) Infant 10-15 woods units/m2
2.) 1-2 years old: 15-20 woods units/m2
3.) Child to adult: 15-30 woods units/m2
a) Factors affecting resistance
i.) Compliance-ease that blood travels through the arteries
1. Constriction and relaxation of smooth muscle of arteries and arterioles
a. ) Sympathetic nervous system
b.) Local tissue metabolism
c.) Hormone responses
d.) Changes in chemical environment
Explain the process of cardiac contraction and At rest, active sites on actin are blocked by troponin and tropomyosin
relaxation. complexes. During action potential, troponin C binds with calcium and moves
the complexes off the actin active site. Actin and myosin interact (contract).
What are the roles of actin, myosin, and troponin in this
process? "Walk-along" theory:
Head of myosin cross-bridge attached to the actin filament at the active site.
Intra molecular forces cause the myosin head to tilt forward on a flexible hinge
and drag the actin filament with it (power stroke)
Myosin head breaks away and interacts with the next actin active site.
Z disc pulls filaments together at the sarcomeres= muscle contraction.
What is the effect of Epinephrine on the cardiovascular Stronger Alpha 1 than Alpha 2. Works on both, equally strong on Beta 1 (renin
system? release), and Beta 2. Positive inotrope. Increases heart rate, smooth muscle
contraction, myocardial contractility, coronary flow, increase systolic blood
pressure, mild increase in diastolic blood pressure.
What is the effect of Norepinephrine on the Slightly stronger Alpha 2 than Alpha 1. Some effect on Beta 1, none on Beta 2.
cardiovascular system? Strong vasoconstriction (smooth muscle contraction). Increase coronary flow,
increase systolic and some diastolic BP.
What is the effect of Dopamine on the cardiovascular Positive inotrope. Increases HR, increases BP (vasoconstriction) Alpha 1, 2, beta
system? 1 and dopamine receptors)
What is the process of generating a cardiac action 0-Depolarization
potential? 1-Early repolarization
What electrolytes are involved? Rapid sodium entering the cell
2. Plateau (repolarization)
Slow sodium and calcium enters the cell
3. Potassium moves out of the cells
4. Return to resting potential
Sodium, Calcium, Potassium
What is the conduction pathway? SA Node, AV Node, Bundle of His, Right & Left Bundle Branches, Perkinje Fibers
