How is a sesame seed bun digested?

Sesame seed buns are a type of bread that are typically made with white flour, water, yeast, sugar, salt, and sesame seeds. The process of digestion for a sesame seed bun is as follows:

1. The bun is chewed and broken down into smaller pieces by the teeth.

2. The bun mixes with saliva, which contains enzymes that begin to break down the carbohydrates and fats in the bun.

3. The bun travels down the esophagus and into the stomach.

4. In the stomach, the bun is further broken down by stomach acid and enzymes, and is churned to mix it with the stomach juices.

5. The partly-digested bun, now called chyme, moves through the pyloric valve and into the small intestine.

6. In the small intestine, the chyme is mixed with bile from the liver, which helps to break down the fats in the bun.

7. The chyme is also mixed with pancreatic juices, which contain enzymes that further break down the carbohydrates, proteins, and fats in the bun.

8. The nutrients from the bun are absorbed through the walls of the small intestine and into the bloodstream.

9. The remaining waste material moves into the large intestine, where it is eventually eliminated from the body.

The entire process of digestion typically takes several hours, and can vary depending on the individual and the amount of bun consumed.
