Which heart chamber functions to pump deoxygenated blood to the lungs? a. Right atrium b. Right ventricle c. Left atrium d. Left ventricle ~~> 1. B: The right ventricle pumps the deoxygenated blood it has received from the right atrium to the lungs. The right atrium pumps deoxygenated blood from the body to the right ventricle. The left atrium pumps oxygenated blood from the lungs to the left ventricle. The left ventricle pumps oxygenated blood to the body. 2. Which lead is t...

Pacemakers of the Heart - Answer Sinoatrial (SA) node Atrioventricular (AV) node Bundle of His Bundle Branches Purkinje Fibers -SA node: p wave -SA node to AV node: PR segment -Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex -Repolarization of ventricles: T wave P wave - Answer sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG AV node conduction...

1 NR509 WEEK 4 EXAM REVIEW QUESTIONS AND ANSWERS, RATED A+/ VERIFIED The sac that surrounds and protects the heart is called the: a. Pericardium. b. Myocardium. c. Endocardium. d. Pleural space. - -a. Pericardium. The direction of blood flow through the heart is best described by which of these? a. Vena cava - right atrium - right ventricle - lungs - pulmonary artery - left atrium - left ventricle b. Right atrium - right ventricle - pulmonary artery - lungs - pulmonary vein - left atri...

1. sinus node: The intrinsic pacemaker. Cell membrane "leakiness" causes spon- taneous depolarization at a rate of 60-100 times a minute. 2. AV node: Acts like a resistor to slow the impulse allowing time for the atria to completely contract before initiating ventricular contraction. Back up pacemaker if SA fails, pacing at a rate of 40-60 times a minute. 3. Bundle of his: "Cable" that passes through the fibrous sheath separating atria from ventricles. Divides into the bundle branches. 4....
