The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air.
And, just to clarify, the kitty litter in your trunk, to be used for traction, needs to be taken out and spread around your tires. Most cars are front wheel drive, so the extra weight alone in the back ain't gonna do you much good.
The kitty litter only has to be placed in each drawer in small paper bags or cloth satchels made from clean rags tied to hold the litter with a string. It is easy for each person to experiment with how much to use depending on the size of the drawer, how much fruit is in it, and when to replace the litter for best results.
