__**FACTS **__
1.Your blood pushes almost five litres of blood from your blood vessels every minute. 2. The red blood cells deliver all the oxygen to the body and then pick up all the spare carbon dioxide taking it to the lungs. 3.The heart is the most important muscle in the body because your heart cleans your blood and it makes sure that you have enough blood in your body.

**__THE PARTS OF THE HEART__ **
There are 14 small hollow chambers in the heart in total and they are called;
 * The Inferior Vena Cava
 * The Descending Aorta
 * The Tricuspid Valve
 * The Right Ventricle
 * The Left Ventricle
 * The Bicuspid Valve
 * The Right Atrium
 * The Left Atrium
 * The Right Pulmonary Veins

Plasma makes up 55 per cent of your blood. Red blood sells (44 per cent) are also in your blood red blood cells help move oxygen around your body when you have realised the oxygen your red blood cells start picking up carbon dioxide and takes it to your lungs then you breath out. Your white blood cells are less than one per sent of your blood there roles are to fight any bad bacteria that gets in to your blood flow. Plasma is for when you get a cut the plasma floats to the surface of your cut to make a scab and platelets are for if your vessels are damaged the platelets start joining together at the site of injury and make a plug that helps seal the vessel and prevent blood loss.the are 5 types of white blood cells: neutrophils, eosinophils, lymphocytes, monocytes and basophils ==== <span style="font-family: 'Comic Sans MS',cursive; font-size: 14pt;">the heart beat It’s when your artrias and ventricles squeeze and relies that makes a heart beat. on an average scale your heartbeats one million times a day. Every day it pumps out trillions and trillions of sells all around your body. Before each beat the heart fills up with blood. Then the heart squeezes and pushes the blood out of your heart. Your heart beats from the minute you were born. it beats on average about 60-80 times per minute.
