===About the Heart===
: The [[heart]] has 4 separate chambers; the [[Right Atrium]], [[Right Ventricle]], [[Left Atrium]] and [[Left Ventricle]].
:[[Deoxygenated]] [[blood]] enters the [[Right Atrium|right atrium]] from the [[Vena Cava]]. The [[atria]] contract, pushing the [[blood]] from the [[Right Atrium|right atrium]] through the [[Tricuspid Valve|tricuspid valve]] into the [[Right Ventricle|right ventricle]]. The [[ventricle]]s contract pushing the [[blood]] out of the [[Right Ventricle|right ventricle]] through the [[Semilunar Valve|semilunar valve]] into the [[Pulmonary Artery|pulmonary artery]] which takes [[blood]] to the [[lung]]s. [[Oxygenated]] [[blood]] returns from the [[lung]]s through the [[Pulmonary Vein|pulmonary veins]] and enters the [[Left Atrium|left atrium]]. The [[atria]] contract, pushing the [[blood]] from the [[Left Atrium|Left atrium]] through the [[Bicuspid Valve|bicuspid valve]] into the [[Left Ventricle|Left ventricle]]. The [[ventricle]]s contract pushing the [[blood]] out of the [[Left Ventricle|Left ventricle]] through the [[Semilunar Valve|semilunar valve]] into the [[Aorta]] which takes the [[blood]] to the rest of the [[body]]s.{| class="wikitable"|-|[[File:HeartDiagramKS4.png|center|400px]]|-| style="height:20px; width:300px; text-align:center;" |A [[diagram]] showing the features of the [[heart]].|}
