BSC2086 Heart QUESTIONS AND VERIFIED SOLUTIONS
The first heart sound, "lubb," marks the point when - ✔✔the atrioventricular valves close
The difference between the end-diastolic volume (EDV) and the end-systolic volume -
✔✔stroke volume Contraction of the chambers of the heart is - ✔✔systole
Parasympathetic stimulation from the vagus nerve results in: - ✔✔a decrease in heart rate
The expandable outer portion of each atrium is called a(n) - ✔✔auricle The QRS complex
represents - ✔✔ventricular depolarization Blood pressure in the large systemic arteries is
greatest during - ✔✔systolic ejection The heart has - ✔✔four chambers. The left atrium
collects blood from the - ✔✔pulmonary circuit and empties into the left ventricle. The
plateau in a cardiac muscle action potential is due to - ✔✔slow calcium channels Vessels
that carry blood away from the heart are called - ✔✔arteries In an intact heart, the
functional pacemaker is the - ✔✔sinoatrial node Blood from coronary circulation is
returned to the right atrium of the heart via - ✔✔coronary sinus Bicuspid valve - ✔✔
