Lab 1.1

Question 1

Atrioventricular Valves

Answer 1

Found between the atrium and ventricle
(Tricuspid = 3 pockets)
(Bicuspid = 2 pockets)

Question 2

Semilunar Valves

Answer 2

Found between ventricle and great vessel
(Aortic and Pulmonary Valve)

Question 3

Pulmonary Circulation

Answer 3

pumps blood to the lungs for gas exchange

Question 4

Systemic Circulation

Answer 4

pumps blood to the body so it can get nutrients and oxygen

Question 5

Coronary Circulation

Answer 5

supplies the heart with nutrients and oxygen

Question 6

Left Coronary Artery

Answer 6

Circumflex Artery - supplies left atrium and posterior left ventricle
Anterior Interventricular Artery- supplies anterior ventricles and interventricular septum

Question 7

Right Coronary Artery

Answer 7

Posterior Interventricular Artery- supplies posterior ventricles and interventricular septum
Marginal Artery- supplies right atrium and right ventricle

Question 8

Electrical Activity of the Heart

Answer 8

SA node sets the heart rate (pacemaker of the heart)
PNS slows the heart rate
SNS increase the heart rate

Question 9

ECG

Answer 9

P Wave - atrial depolarization
QRS Complex - ventricular depolarization
T Wave - ventricular repolarization

Question 10

Systole

Answer 10

Contraction

Question 11

Diastole

Answer 11

Relaxation

Question 12

Tachycardia

Answer 12

abnormally fast heart beat

Question 13

Bradycardia

Answer 13

abnormally slow heart beat

Question 14

Stroke Volume

Answer 14

amount of blood pumped out per systole

Question 15

EDV

Answer 15

volume of blood in ventricle before ejection

Question 16

ESV

Answer 16

volume of blood in ventricle after ejection

Question 17

Equation

Answer 17

Cardiac Output = Stroke Volume x Heart Rate
