Look at the <u>diaphragm</u>, the musculotendinous sheet that separates the <u>thoracic cavity</u>, containing the heart and lungs, from the <u>abdominal cavity</u> that contains the abdominal viscera. There are three tubes that pass through the diaphragm. Once again, find the esophagus, and then identify the other two: the posterior <u>vena cava</u> and the <u>dorsal aorta</u> | Look at the <u>diaphragm</u>, the musculotendinous sheet that separates the <u>thoracic cavity</u>, containing the heart and lungs, from the <u>abdominal cavity</u> that contains the abdominal viscera.

Cut through the ribs close to the upper limbs, with your scissors. Cut across the distal end of the ribs, and through the clavicles and remove parts of the ribs that can readily be cut out. Don't remove the sternum connecting the two sets of ribs in the midline lying above the top of the heart since there are blood vessels right below it that we want to preserve. Look at the position of the heart within the thorax and note its relationship to the lung.<br><br> | Cut through the ribs close to the upper limbs, with your scissors.
