What is the anatomy of the systemic circulation? |
1. Right atrium 2.Right ventricle 3.Pulmonary Trunk&Arteries 4.Pulmonary capillaries (Blood loses CO2 and gains O2) 5.Pulmonary veins 6.Left atrium 7.Left ventricle 8.Aorta and systemic arteries 9. Systemic capillaries (blood loses O2 and gains CO2) 10. Superior vena cava, inferior vena cava, Coronary Sinus |
|
sample question |
1. P wave 2. PQ interval 3. QRS Complex 4. ST segment 5. T wave 6. QT interval |
|
|
True or False: The heart beats without extrinsic stimulation from the ANS. |
True |
|
|
True or False Autorhythmic cells are located only in the sinoatrial node |
False |
|
|
Each heart chamber contracts separately, first the right atrium, then the right ventricle, left atrium, and left ventricle. True or False? |
False |
|
|
The ECG records the electrical stimulation of cardiac muscle by the conduction system and not the contraction of the muscle itself |
True |
|
|
List the components of the cardiac conduction system in the normal order of depolarization |
1. SA node 2. AV node 3. AV bundle 4. R and L bundle branches 5. Purkinje fibers |
|
|
How would damage to the left bundle branches affect blood flow in the systemic circuit? |
The blood flow in the systemic circuit would decrease because the left ventricle would pump less blood. |
|
Label the illustration of the electrical conduction pathway in the heart. |
1. Right Purkinje fibers 2. Right AV bundle branch 3. Atrioventricular bundle 4. Atrioventricular node 5. Sinoatrial node 6. left AV Bundle branch 7. Left Purkinje fibers |
