So how much do you know about the body?I bet that you didn’t know that the heart pumps (estimated)1 million times a day!Your heart is the most important part of your body because it makes sure that all of the nutrients ,water and oxygen gets to the correct places.Think about it like this ,your heart is in a ball game but his partner is so far away that the heart has to throw very far and instead of them throwing a normal ball they’re actually throwing nutrients ,water and oxygen.When they get thrown it goes into your veins and a delivery truck comes and picks it up and drives of and takes it where it needs to be.Now there is more than 1 truck there are loads of them or your body system would be slow and you wouldn’t get enough of what you need , I have explained what that truck does let’s call it truck 1 so now I’m going to tell about what truck 2 does.Truck 2 carries all of the stuff u don’t need, its basically like rubbish, so now I’ve explained what the trucks and the heart do I’ll explain what the veins are for.There are things called red and white blood cells inside of you and they travel through your veins first I’ll tell you what the red blood cells are, the red blood cells are pretty much your blood so when you cut yourself the red liquid that’s coming out of you isn’t actually liquid it’s little particles inside of you.The white blood cells fight all of the illnesses you have so that you don’t get even more ill. Did you know that when you were younger the doctors put a tiny bit of measles in you so that if your white blood cells saw it again they could fight it of.
