There's a hierarchy to this; in the largest form, the heart is made from muscle tissue; muscle tissue is made from cells, and cells are composed of elements.
The heart is hollow and shaped like a cone. It is made of specialized muscle tissue which allows it to beat your entire lifetime. It is relatively small and is about the same size as your closed fist. Your teacher's heart weighs about 10 oz, and is about 5 inches long and 3 1/2 inches wide at its broadest point.
It pumps 30 times it's own weight each minute. Here's a good arithmetic question for you - how much does it actually pump in a minute? If you did your math right - you came up with an answer of 5.3 quarts.
How much would it pump in a day (24 hours)? (answer 1800 gal) and how much would it pump in a year? (answer 1.3 million gal) WOW! that sure is a lot of blood! Once that blood leaves the heart it travels about 60,000 miles of blood vessels before it returns back to the heart. If the average heart beats 60 times a minute how many miles does the blood travel in an entire 60 seconds?? Anything that can work that hard with with only a little rest between beats has to be something very strong. It's a muscle.
