Please judge this passage.? Well, This my creative writing assignment for Science on the 'journey of oxygen'. This is in the point of view of an oxygen molecule. I posting it in science because my teacher told us the grammar and other details like that don't matter as much as the accuracy of the information and the usage of scientific terms. Can you please read it and judge it and suggest what I should add more, especially in the end. All I knew that I was being sucked into a huge black hole. I cringed a little but I knew my time to be useful had come. Vital as I am for all living beings, this day was just around the corner. Yet, I couldn’t feel more excited! Of course, there were tons of others like me. We are too small, microscopic in fact, to be just 5 or 6 in numbers. There were also many other types of First, as I entered the nasal cavity, I suddenly found myself, filtered warmed and moistened. In the outside of the nose, these nostril hairs first filtered out all the larger, unwanted particles. Quickly as we shifted to the inside of the nose, tiny, hair-like cilia trapped all the small particles. Also mucous glands in the inside of the nose produced this sticky mucus which then trapped all the dust particles. Feeling much cleaner, I entered the pharynx along with the sticky mucus and the particles. Very soon, I found myself entering the trachea. I passed the thin flap of tissue, known as the epiglottis, which prevented the stuff they called food from entering in. as well as the strangely vibrating Larynx. I also caught a tiny glimpse of the oesophagus, but that was all. It so fast and before one could say lungs, I found myself entering one as the trachea branched of into two bronchi. I noticed, in the entire tube system the tiny cilia. These bronchi also started to branch into smaller bronchioles. In the end of the tube, I found myself entering an alveoli sac or an alveolus. It was close to the walls of the similarly one cell thick blood vessel known as capillaries. I crossed over from the alveolus to the capillaries by diffusing into the capillaries which had a lower concentration of oxygen. Due to the small size of the capillaries, the distance between the lungs and the bloodstream was very short. Soon, I was in the blood. I was carried in the blood by these a special carrier called the Haemoglobin. The blood was quickly pumped to the entire body. I entered a body part and aerobic reparation began to take place. I burned the glucose and the resulting product was carbon dioxide, water and 38 ATP (adenosine triphosphate) molecules produced in to stages occurring in the cytoplasm and the mitochondria. My job was done. Please serious answers. Will chose best answer today itself. Biology - 1 Answers - 2012-01-29 03:11:37 Best Answer I really liked it. You could add by saying how it was carried around the body. Adding some of the veins, arteries and the chambers of the heart that it passed through. You could elaborate on the Haemoglobin by saying that it contains iron and that one haemoglobin will carry 4 O2 molecules. Also instead of saying "burned the glucose" say oxidised. Say that the haemoglobin is contained in the red blood cells (Which are not like other cells as they have no DNA or nucleus). All Answers Answer 1 I really liked it.
