Despite how it may seem at times, we all have a heart.

But how much does a heart weigh?

The human heart in a man is larger than a woman’s heart. It will weigh 10 to 11 ounces (283 to 312 grams).

A woman’s heart weighs around 8 to 9 ounces (227 to 255 grams).

A human heart beats 100,000 times a day. It also pumps approximately 2,000 gallons of blood each day into a network of blood vessels. Those vessels are more than 60,000 miles in length.

Think about that for a minute. It’s amazing!

However, humans are not the only ones with a heart. You’ll find it in most animal species, as well.

It’s required to pump blood filled with oxygen and nutrients in the body. At the same time, it helps to remove metabolic waste from important parts of the body.

Larger animal species have more blood to pump around their bodies. So their hearts are bigger and more powerful.
