Answers
Explanation:
The heart is the hardest working muscle in the human body. Located almost in the center of the chest, a healthy adult heart is the size of a clenched adult fist. By age 70, the human heart will beat more than 2.5 billion times. The heart is always working. It pumps about 2,000 gallons of blood daily.
A child's heart works just as hard as an adult's heart. In fact, at rest, a baby's heart may beat up to 130 to 150 times a minute. An adult's heart often beats between 60 and 100 times a minute. The rate at which the heart pumps gradually slows down from birth to teen years.
The cardiovascular system is made up of the heart and blood vessels. It circulates blood throughout the body. A healthy cardiovascular system is vital to supplying the body with oxygen and nutrients.
