Explore Have students in groups of four do a gross examination of the stomach and report observations of the stomachs using anatomical terminology.
Students begin the study by performing a horizontal sagital cut through the length of the stomach.
Have the student collect stomach contents and observe stomach and contents under a dissection scope. Explain Point out rugae, sphincters, mucosa, and sub-mucosa. Demo a transverse cut through the stomach wall. Describe glandular structures on the histologic slide. Describe comparative anatomy between the ruminant and non-ruminant stomachs.
