How does your heart work


The heart is a cone shaped muscle that circulates the blood in your body. This muscle can be or is about the size of an adult’s fist. The heart is the most important organ in your body, why? It is basically a blood pumping machine.  Without your heart your blood wouldn't be able to pass through your veins.



Here is an Age Pulse chart I found on the websites below I thought this chart was very interesting. I wonder why our heart gets lower as we grow older?
Newborn   130
3 months  140
6 months  130
1 year       120
2 years     115
3 years - 6 years  100
8 years     90
12 years   85
adult 60 - 100
