# How Many Times Does Our Heart Beat In A Day?

On an average, the heart of an adult beats about 72 times a minute and that of a child beats between 90 and 120 times a minute. Hence, in a day (that is, 1, 440 minutes), on an average, the adult heart beats 103, 680 times and a child's hearts beats between 129, 600 and 172, 800 times.

The average heart is about the size of a fist. It weighs 300 grams. Blood first flows from the body to the right atrium or the right auricle, then to the right ventricle, then to the lungs, then to the left atrium or the left auricle and then to the left ventricle, before finally flowing back to the body.

On an average, we have about 5.6 litres of blood in our body. In the average lifetime, a heart pumps an amount equivalent to approximately one millions barrels of blood. That is approximately equivalent to the entire capacity of three supertankers. The aorta is the largest artery in the human body and is diametrically about the size of a garden hose. On the other hand, the capillaries are the smallest arteries in the human body, and it takes about ten of them to equal the thickness of a single strand of human hair.

GREAT WORK DUDE! I have homework, that involves bout a heart and all that crap and you made osme of the questions easier to answer
Take the pulse/heart rate, or beats per minute, and multiply by 60.
The multiplier 60 converts the beats per minute to beats per hour.
Take that answer and multiply by 24.
The multiplier 24 converts beats per hour to beats per 24 hour day.

Ie. Average pulse = 70
70 x 60 = 4200
4200 x 24 = 100800

A Normal Rate for an Adult Heart to beat is 60-100 beats per minute.
Using 60-100 beats per minute as the normal range:

In one day your heart beats:

86,400-144,000 times!!!

Depends on your age. Like a 8 year old's heart could beat 96 times a minute but a 50 year old's heart may beat 60 times a minute.

At an avg of 80beats / min the daily total = 115200

70 beats s right
thanked the writer.
It all depends on how many times your heart beats in a minute. Is varies per person depending upon the environment you are.
When at rest, the normal person's heart beats about 70 times a minute, that would give 100,800 beats per day.
An adult heart beats approximately 100,000 times a day.

It depends on what mood your in and if your exercising. It also depends on your age. My heart rate is 120 beats per minute when I'm nervous. It could be the same for you. 120 x 1440 is your heart rate. 1440 is the number of minutes in a day. Its all just about MATH.

An adult is about 70 to 80 per minute, but it is normal between 60 and 100. When you are in some exercise, the beat will become faster. And woman's is faster than man's heart beat. Children are faster than adults. A new-born child can approch to 150 every minuter. In average, if a person can live to 100 years old, then, his heart beat is about 4 billion in total.

For an adult 70 times a min so 70 multiply by 60 min= 4200
4200 beats an hour than 4200 multiply by 24 hours= 30800

You got every thing right. But 24x4200 is 100800. I double checked myself. 100,800 beats per day.
Well for an adult the average would be around 72 and for a child it would be from 90 to 120

Depends on a lot of different things, like how old you, what your health is like, and if you have an irregular heart-beat or not... An infant, adolescent-child, and adult all have different rates of heart beats... Have someone check your pulse to see how many beats per minute you have, then do the math from there...60 seconds in one minute, 60 minutes in an hour, and 24 hours I one day...

Different persons have different heart beat rate. A normal person heart beats 60 to 100 times per minute. Suppose if a person heart beats 75 times in a minute then it would be equal to 75X1440=108000/- beats per day.
