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.
Hereâs how. 1  Add equal parts kitty litter to latex paint in the can (one part paint to one part kitty litter). 2  Stir the cat litter into the paint until it has an oatmeal-like consistency that will not spill out. 3  Allow the paint and cat litter mixture to sit for one hour.  Throw the dried paint in the can in the garbage with the lid off.
