How long does it take for you blood to complete one cycle?
A
1 minute
B
2 minutes
C
3 minutes
D
10 minutes
Explanation: 

Detailed explanation-1: -Assuming a healthy heart and a typical rate of 70 to 75 beats per minute, each cardiac cycle, or heartbeat, takes about 0.8 second to complete the cycle.

Detailed explanation-2: -On average, it takes about 45 seconds for blood to circulate from the heart, all around the body, and back to the heart again. An average adult’s heart beats more than 100, 000 times a day.

Detailed explanation-3: -How Fast is Blood Pumped Through Your Body? Traveling at roughly 3 feet per second, a blood cell in the average person travels through the ENTIRE body in about one minute.

Detailed explanation-4: -Your body has about 5.6 liters (6 quarts) of blood. This 5.6 liters of blood circulates through the body three times every minute. In one day, the blood travels a total of 19, 000 km (12, 000 miles)-that’s four times the distance across the US from coast to coast.

Detailed explanation-5: -I also collected the following, potentially relevant “facts” about the heart and circulatory systems (generally, where it matters, for an adult male): Blood travels an average of 3-4 mph6.
