The cardiac events that occur from the beginning of the heart beat to the next heart beat are called the cardiac cycle. During the cardiac cycle:
1 The atria and the ventricles contract simultaneously
2 The atria contract before the ventricles
3 The ventricles contract before the atria
4 All of the above
Explanation:
The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle. The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole. Both the atria and ventricles undergo systole and diastole, and it is essential that these components be carefully regulated and coordinated to ensure blood is pumped efficiently to the body.

Statement A : Stroke volume is the amount of blood which is pumped out by each ventricle during a cardiac cycle. Statement B : Cardiac output is defined as the volume of blood pumped out by each ventricle per minute.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Both the given statements are correct.

The typical 'lub-dub' sounds heard during heartbeat are produced due to
1 Closure of semilunar valves
2 Closure of bicuspid and tricuspid valves
3 Closure of bicuspid and tricuspid valves followed by semilunar valves
4 Opening of bicuspid and tricuspid valves followed by semilunar valves
Explanation:
During each cardiac cycle, two prominent sounds are produced which can be easily heard through a stethoscope. The first heart sound (lub) is associated with the closure of the tricuspid and bicuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves.

Select incorrect answer:
1 A higher heart rate implies more efficient heart pressure.
2 A normal resting heart rate for adult ranges from 60 to 100 beats a minute.
3 Consult your doctor if your resting heart rate is consistently above 100 beats a minute.
4 A lower heart rate implies more efficient heart function and better cardiovascular fitness.
Explanation:
Causes of tachycardia include: Heartrelated conditions such as high blood pressure (hypertension) Poor blood supply to the heart muscle due to coronary artery disease (atherosclerosis), heart valve disease, heart failure, heart muscle disease (cardiomyopathy), tumours, or infections.
