Can anyone fill in the gaps??? oxygen molecule making a journey into the lungs?

First, I got right up her nose, and spent some time going round some big folds and flaps called the …………, and I must say it did warm me up a lot. Then I moved on down the …………, which is supposed to have different regions behind the nose, mouth and larynx, but it all looked much the same to me. Well, there was a choice at one point, where I could have gone straight down the ………, but there was a sign saying that way went to the stomach, and I didn’t fancy that. It’s a good thing the ………… was open, I’ve heard that sometimes it’s shut and you can’t go through. I did have to show my pport here, because I was going from the upper to the lower ………… So, anyway, I went down past the …………, where a lot of air molecules had been having great fun playing on a big ‘organ’ called the vocal cords, and into the ………… This was pretty big, and it is held open by big C-shaped rings of …………, but the walls were all slimy with ………… I avoided the walls, because there were all these ………… beating and moving the slime and muck back up to the throat. I had to choose between the left or right …………, and after that there were heaps of choices as I went into smaller and smaller …………. , but it didn’t matter because they all ended up in a cluster of tiny caves called ………… There was a big ………… checking out for trouble, especially bacteria without pports, and it ate the ones it caught! Fortunately I was too small to be noticed. At this point there seemed to be no way to go any further, but, being small, I slipped through all the layers of the …………, into a blood capillary. Soon a red blood cell came along, with a spare seat on one of the haeme units on one of it’s ………… molecules, so I hopped on board, for my trip to the heart.
