On Tuesday, I did a dissection of a sheep’s pluck(a sheep’s pluck is a group of organs) this time we had the respiratory system. When we got there we discussed how to use the scalpel and other safety rules. After instruction, we were given a scalpel and a pluck. First we cut the trachea off and stuck our finger into the lung to feel the bronchi tubes the split off into each lung. Second we cut the right lung off and then into 3 pieces. We each grabbed one and squeezed the surfactant (fluid in the lungs to keep it from ripping the tissue) out of the lungs. After that, we washed our hands then left.
