A Journey Of Heart Anatomy

    Once upon a time, there was a city known as Human. The city is managed by many departments situated at certain position and having their own portfolios. The major department is situated at the space called Mediastinum. The head office is named as Heart and ruled by several officers like Atria, Ventricle and Valve. Besides officers, Heart do also employ Vessels as helper in transportation. All the officers and the helpers deals with one major matter  known as Blood. There are two type of blood namely deoxygenated blood and oxygenated blood.

     To make things easier, Heart is divided to the left and right by Septum. Then each side is further divided into upper and lower chamber. The upper chambers are ruled by Atria while the lower chambers by Ventricles. In between there is another officer named  valve. Valve act as information transfer controller. Valve ensure that the Blood does not travel in opposite direction. 

     Since there are two types of blood, Heart divides the role of managing deoxygenated blood to the right side while oxygenated blood is managed by left side of Heart. 

    There are 4 major Helpers in this head office. They are Aorta , Vena Cava, Pulmonary Artery and Pulmonary Vein. Pulmonary Vein and Aorta deals with oxygenated Blood. Pulmonary Artery and Vena Cava transports deoxygenated blood.
