25 Crazy Things You Might Not Know About Blood

Posted by , Updated on October 1, 2015

It’s red and you need it. That’s what most people know about one of the most important substance in the world. Your blood keeps you alive and without it, nothing in your body could get to where it needs to be. Blood brings oxygen to your cells and removes waste products (functions you simply can’t live without). But there is more to blood than meets the eye. Did you know that most of your blood consists of water? In spite of this, however, there is no way to create blood artificially. It is completely up to our body to create it. In fact, red blood cells start their life in your bones (well, your bone marrow to be exact). After mutating for seven days they are released into your blood stream to begin their important duties. Thanks to the relentless pumping of your heart, each blood cell will now make a complete cycle through your body in just about 30 seconds. Each red blood cell will continue to circulate for over 100 days before it dies, and is replaced by a new red blood cell. Isn’t amazing how your body works together to sustain you? These are 25 Crazy Things You Might Not Know About Blood. If you want to know more about how your body works, take a look at these 25 amazing facts about the human body you may not be aware of.
