Have you ever imagined the life without air? Perhaps you felt tight in the breast and thought the word, 'death'. Like this, breathing is one of the most basic instincts of human life. But breathing in the oxygen which accounts for 20.946% of the atmosphere, however, is not easy as much as saying 'like breathing'. In summary, the human respiratory system can be divided into 3 period as follows.
The first period is inhaling. There is a diaphragm under the lungs, and it can be transformed. When it contracts and increases the volume of the lungs, the air let come into the lungs through nose and bronchial tubes. At this moment, the oxygen in the air goes to 'alveolus', seemed like a micro raspberry, and dissolves into the blood.
Next is the circulation. The body consist of a huge amount of cells, and each cell needs to supply oxygen when it acts. Circulation based on heart`s pumping, the oxygen-filled blood goes to all around of body through arteries. When it arrive at a capillary vessel, like a tiny corn silk, oxygen adhered to hemoglobin in a red blood cell is delivered to the cells. Instead, the blood receive carbon dioxides from cells.
Last, exhaling. Blood returned to the lungs through veins put out the carbon dioxides. When carbon dioxides go out through the alveolus, a diaphragm puffs up, then the air exit out to outside of body.
The breathing, thinking nothing of difficulty, is be provided in such of complex procedures. But the respiratory system works quietly in now. Like this, when having a curiosity, we can solve the question by using basic scientific knowledge. And also, finally, we can understand our own body.
Wonderful writing!
ReplyDeleteI enjoyed your essay~ very interesting and at the same time informative! it's not like i never knew about the whole process but it came clear to me now!
Except for a few mistakes of grammar and structure of the sentences, it seems to be a great work overall.
Yet, the first sentence of the conclusion isn't quite clear to me. I kinda of get where your are heading, but it would have been better if you clear out the sentence. Also a brief summary of three stages mentioned in the body would complete your conclusion with better flow. Good closing though? ;)

Last, exhaling. Blood returned to the lungs through veins put out the carbon dioxides. When carbon dioxides go out through the alveolus, a diaphragm puffs up, then the air exit out to outside of body. And these three steps repeat over again.
The breathing is progressed in such of complex procedures; inhaling, circulation and exhaling. When just one of the respiratory system ceased, our life can be threaten. So we should know value of respiratory system. Moreover, we need to maintain our health good as possible.
