DIGESTION

To nourish the body, the digestive system breaks down food into nutrient molecules, absorbs them into the blood stream, and eliminates food by-products.

Food moves from the mouth, passes through the esophagus, and arrives in the stomach. Here, enzymes and hydrochloric acid mix with the chewed food churning it into a thick liquid.

The liquid then enters the small intestine. Here, nutrients such as carbohydrates, proteins, and some fats, are reduced to tiny molecules.

Along with vitamins and minerals, they leave the intestine through tiny projections called villi and cross capillary beds into the bloodstream. Undigested food moves into the large intestine and then leaves the body.

The ending is what happens and was not graphic at all. There's no reason for it to be "awkward".
