How does the plan on which a watch is made compare with thaton which the body is constructed ? In a human body cut down themiddle what chief divisions would you find ?. 6 THORAX AND ABDOMEN. 9. The Ventral Cavity, as you perceive in the fig-ure, does not reach up into the neck or head. Itexists only in the trunk of the body, and is dividedinto an upper story, B^ the chest or thorax^ and alower story, C, the abdomen^ by a partition, d^ whichforms the floor of the thorax and the ceiling of the ab-domen. This partition is the diaphragin. How far inyour own body the chest-cavity extends you can find outpretty accurately by beginning at the bottom of the neckand feeling down along the middle of the front of yourtrunk till you feel no more bones through the skin:that level marks the bottom of the thorax. 10.
