Hello everybody! I am Jack, the human body of a 25 year old man. Having shared a very close relationship with the boy, I can surely say that he has taken good care of me. As a healthy body, let me take this opportunity to introduce all the members of my system, who you know as organs of the human body. They are responsible for making me who I am. At this point, I am in slight confusion of where I should begin from, but as Mr Brain make me overcome, I’ll begin with his introduction.

Mr Brain
Being vertebrate in nature, Mr Brain is the leader of the nervous system. The nervous system has nothing to do with the English meaning of the word ‘nervous’. In fact Mr Brain is the member accountable for welfare of the boy. It is he who activates muscles and secretes chemicals to respond to a stimuli and most importantly think. Many have tried to understand the policies of Mr Brain’s legacy, yet it remains a mystery. His office is located in the head within the security of the skull guards.

Miss Heart
The popular of them all is Miss Heart. The women-in-charge knows how to beat her drum to keep jack alert about his anxiety levels. She collects all the de-oxygenated blood and pumps it through the right-ventricle. The blood then goes to Mr Lungs so that he can throw out carbon dioxide and breath in oxygen. Heart has divided her office in the right ventricle and the left ventricle for ease of operations of pumping the blood. A unique design of her office has brought about systematic circulation of blood in all other human organs too.

Mr Lungs
Mr Lungs and Miss Heart are significantly interdependent on each other. He mainly transports the atmospheric oxygen to the blood and give out carbon- dioxide. Other than that, he filters out the tiny blood clots that are there in the veins, maintains the pH level and is a shock-absorber for the heart. Let me take a moment here, to show my heartfelt gratitude to Jack for treating Mr Lungs with regular exercise and healthy dietary intake. » Read more: Organs of Human Body
