MCQ
Match the following cardiac valves with their location:
A. Tricuspid valve
B. Bicuspid valve
C. Semilunar valve
D. Atrioventricular septum
i. At openings of ventricles into great arteries
ii. Connects atria and ventricles of same side
iii. Between right atrium and right ventricle
iv. Between left atrium and left ventricle
✅ Correct Answer: D
The tricuspid valve is between RA and RV; bicuspid is between LA and LV. Semilunar valves open into pulmonary artery/aorta. Atrioventricular septum separates chambers on the same side.

MCQ
What is the average human heart rate per minute?
✅ Correct Answer: A
The SAN typically generates 70–75 action potentials per minute, setting the heart rate.
MCQ
Assertion (A): Closure of tricuspid and bicuspid valves causes the first heart sound.
Reason (R): This happens at the beginning of atrial systole.
✅ Correct Answer: B
First heart sound (lub) is due to closure of AV valves, but it occurs at start of ventricular systole, not atrial. A is true; R mistimes the event.
MCQ
Where is the human heart located?
✅ Correct Answer: C
The heart lies in the thoracic cavity, centrally placed but tilted to the left.
