How does your body turn food into poop

The process by which the body turns food into poop involves several stages of digestion and absorption. Here's a detailed breakdown:

1. **Ingestion**: The process begins when food is ingested through the mouth. Chewing breaks the food into smaller pieces, and saliva, containing enzymes like amylase, starts breaking down carbohydrates.

2. **Swallowing and Esophagus**: The chewed food (now called a bolus) is swallowed and moves down the esophagus through a series of muscle contractions called peristalsis.

3. **Stomach**: In the stomach, gastric juices containing hydrochloric acid and enzymes like pepsin further break down food, especially proteins. The food becomes a semi-liquid mixture called chyme.

4. **Small Intestine**: The chyme moves into the small intestine, which is divided into three parts: the duodenum, jejunum, and ileum. Here, several processes occur:
- **Duodenum**: Bile from the liver and gallbladder emulsifies fats, and pancreatic enzymes continue the digestion of carbohydrates, proteins, and fats.
- **Jejunum and Ileum**: Nutrients are absorbed through the walls of the small intestine into the bloodstream. The inner surface of the small intestine has villi and microvilli, which increase the surface area for absorption.

5. **Liver and Pancreas**: The liver produces bile, stored in the gallbladder, which helps digest fats. The pancreas produces digestive enzymes and bicarbonate to neutralize stomach acid in the chyme.

6. **Absorption**: Nutrients like amino acids, simple sugars, fatty acids, vitamins, and minerals are absorbed into the bloodstream via the walls of the small intestine. Water and some soluble fibers are also absorbed.

7. **Large Intestine (Colon)**: The remaining undigested food moves into the large intestine. Here, water and electrolytes are reabsorbed, and beneficial bacteria help break down some of the remaining substances. This process turns the liquid chyme into a more solid form.

8. **Formation of Feces**: As water is reabsorbed, the remaining material becomes more solid and is formed into feces. This process involves the ascending colon, transverse colon, descending colon, and sigmoid colon.
