Heart and Blood Vessels in Children

LIke ThisLIke ThisLIke ThisLIke ThisLIke This

The heart is the hardest working muscle in our bodies. A baby’s heart can work harder than an adult’s heart: Up to 190 times a minute versus 60 to 100 times a minute. This rate naturally slows down as your baby grows.

During an average person’s lifetime, the human heart will beat more than 3 million times, pumping about a million barrels of blood.

The cardiovascular system—the heart combined with the blood vessels—is responsible for circulating blood throughout the body. It’s vital to supplying the body with oxygen and nutrients.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
