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