So I was up really really late working on homework since I slacked off until ohh... midnight. Here is the awesome shit I write at 4 in the morning (I had to trace the pathway through the respiratory and circulatory systems of an air molecule through the body for anatomy):

Flight of Steve - the Little Air Molecule that Can

There once was this little air molecule named Steve. Steve wanted to explore the world but his big air molecules would not let him because they said he was still too small. Steve paid no heed to them and one day decided to go off on his own and have an adventure. He flew around for several days waiting for something exciting to happen when he bumped into a something very large. He could not figure out what it was, but all of a sudden he felt himself being sucked into a dark hole. Oh no! Is this the end of Steve? Has his time come up, after only such a short journey? No, my friends, that’s where his journey begins...
After Steve gets over his initial shock of being sucked into a dark and warm hole, he decides to make the best out of this experience. Though Steve may not know it, we know that he has been sniffed in through the nostrils by a passing stranger whom we will come to know as Ted. We will trace the flight path of our little hero, Steve, through the respiratory and circulatory system of Ted. After Steve passes through the nostrils, he will then go through the nasal cavity the nasal conchas. Then he will go through the pharynx where he will also pass by two subdivisions of the pharynx - the nasopharynx and the laryngopharynx (mighty big words for such a small molecule...), respectively. Then, Steve will glide through the epiglottis, past the hyoid bone, which will lead him into the larynx. In the larynx, Steve will pass by the vocal cords that keep vibrating whenever Ted would talk. Steve will also see the thyroid and cricoid cartilages as he passes them to go into the trachea. Here, Steve will have to go through about 20 cartilaginous rings before hitting the thoracic cavity, where it will split into the right and left bronchi. Steve has reached a fork in the road! Which way will he turn? He decides to take the right pathway to the right primary bronchus, followed by the secondary and tertiary bronchi, and eventually, the terminal bronchiole. Steve then goes through the pulmonary artery, (He’s in the lungs! ) which leads into the pulmonary arteriole. Uh oh. It’s beginning to be a tight squeeze for Steve to pass through the capillaries. Maybe he shouldn’t have eaten that extra burger for lunch. Anyway, Steve makes it through the capillaries safely. Now, if Steve is of the carbon dioxide family, he would diffuse from the blood within the capillary into the alveolar duct and into the alveolus. But since he is an oxygen, he keeps going through the capillary. However, he sees some molecules that look just like him squeeze through the thin capillary walls. Steve hopes a fight won’t break out because there isn’t much room for many more oxygen molecules... Steve then makes it out safely through the pulmonary venule, and then pulmonary vein. Whew. Steve need a break. After a quick nap, Steve decides to go on with his adventure. From pulmonary vein, he will enter the left atrium of the heart, through the mitral valve (he had to be careful since the valve almost closed on him!), and into the left ventricle. He then goes through the aortic valve, into the arty, into the systemic arteries, and capillary arteriole where he will be in the capillary bed in muscle. Here, Steve will go through a similar process like the capillary bed in the lungs. However, this time, he is the one that will get diffused into the alveolus and gets transferred into cells. The cells will travel through the entire body, carrying Steve with it (it’s like a Taxi!). Where will Steve go from here? Stay tuned till next time...
