Sure, here are the answers to your questions:1. **Functions of the Digestive System:** - **Ingestion:** Taking in food through the mouth. - **Digestion:** Breaking down food into smaller molecules. This includes both mechanical digestion (chewing, churning) and chemical digestion (enzymes breaking down food). - **Absorption:** Nutrients from digested food are absorbed into the bloodstream through the walls of the intestines. - **Excretion:** Removal of indigestible substances and waste products from the body.2. **Parts of the Small Intestine:** - **Duodenum:** The first section, where most chemical digestion occurs. - **Jejunum:** The middle section, where a significant amount of nutrient absorption takes place. - **Ileum:** The final section, which absorbs vitamin B12, bile salts, and any remaining nutrients.3. **Parts of the Stomach:** - **Cardia:** The area where the esophagus connects to the stomach. - **Fundus:** The upper part of the stomach, which stores undigested food and gases released during digestion. - **Body (Corpus):** The main central region of the stomach. - **Antrum:** The lower portion, which grinds up food and mixes it with digestive juices. - **Pylorus:** The passage at the lower end of the stomach that opens into the duodenum.4. **Function of the Liver:** - **Metabolism Regulation:** Processes nutrients absorbed from the small intestine. - **Detoxification:** Filters and detoxifies chemicals and metabolizes drugs. - **Bile Production:** Produces bile, which helps digest fats. - **Storage:** Stores glycogen, vitamins, and minerals. - **Synthesis:** Produces important proteins for blood plasma, such as albumin and clotting factors.5. **Function of the Gallbladder:** - **Bile Storage:** Stores and concentrates bile produced by the liver. - **Bile Release:** Releases bile into the small intestine (duodenum) to aid in the digestion and absorption of fats.These functions and parts are essential for the proper functioning of the human digestive system.
