Question

The heart is an organ which beats
A. Twenty hours in twenty four hours
B. Ten hours in twenty four hours
C. Continuously
D. Eight hours in twenty four hours

Answer 1

Hint: The heart is a muscular organ roughly of a fist size, positioned just behind and somewhat left of the breastbone. The heart pumps blood via a network of arteries and veins referred to as the cardiovascular system. The coronary arteries run along the heart’s surface and supply oxygen-rich blood to the heart muscle. Enclosing the heart is a sac known as the pericardium.

Complete solution
Option A. Twenty hours in twenty four hours: Not a correct option.
Option B. Ten hours in twenty four hours: Not a correct option.
Option C. Continuously: The heart beats continuously. The human heart beats around 100,000 times a day, this totals up to 3 million beats over an average lifetime. The heart rate of a person or the number of times the heart beats per minute, depends on various factors, including age, fitness level, body size and medication.
Option D. Eight hours in twenty four hours: Again, not a correct option.

Answer. Option C is correct

Note:
The heart does not require a brain to keep beating. The heart possesses its own electrical system that causes it to beat and pump blood. Due to this, the heart can continue to beat for a short period of time after brain death, or after being taken out from the body. The heart will continue to beat as long as it contains oxygen.
