Draw it a couple of inches below the stomach because the large intestine will end up going on top of it. The small intestine is a large curving tube that you can draw as squiggly lines beneath the stomach in the center of the body, taking up about half of the width of the body. If you drew a pharynx, the diagonal line can be the epiglottis. The epiglottis is a small flap just below the pharynx that directs food into the esophagus. It you wish to make your model more advanced, you can also include the epiglottis.In your model, you can simply draw a small diagonal line towards the top of your esophagus and the part above the line can be the pharynx and the part below can be the esophagus.
The pharynx is located behind the mouth and moves food into the esophagus. If you wish to make your model more advanced, you can include the pharynx.The esophagus is made of smooth muscle that relaxes and contracts to move your food down with a wavelike motion, called peristalsis. The food moves from the mouth into the esophagus, which carries it down into the stomach.It should be fairly narrow, about 1/5 the width of your model's neck. At the end of the mouth, draw a small tube that extends straight down into the center of your model’s torso.
