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.
Clumping cat litters are those that are designed so that urine and feces can be removed easily from the box without having to empty the entire box. Most contain a material known as bentonite that allows the litter to form a nice solid clump as the litter absorbs liquid.
