Your Heart Story
The cardiovascular system is compromised of the heart, blood, and blood vessels and at times of high impact activity, the whole system is pushed to its limit. We’re going to take a look at which exercises offer us the greatest cardio workout, but before then, did you know…?
The circulatory system is long! If everything was laid out end to end, arteries, capillaries, and veins, it would stretch 60,000 miles! And all of that fits inside your body.
If your heart beats 80 beats per minute, 4,800 times an hour, that equals to 115,200 times per day. So when you’re 80 years old your heart will have beat 3,363,840,000 times!
Your heart pumps a lot of blood! On average your heart will pump one to seven gallons of blood a minute. That’s as much as 2,000 gallons a day.
Blood is always red, never blue. Blood is always red but our veins are blue because of light waves. Light has to go through the skin to illuminate our veins. Red and blue have different wavelengths, so they penetrate at different degrees of success. This is why our veins look blue.
The human heart is about as big as your fist. If you’ve ever wondered how big your heart is just make a fist. It isn’t very big, yet it’s the strongest muscle in our body.
Your heart doesn’t actually beat. That thumping, beating sound you hear is caused by the valves clapping open and closed.
