Certainly! 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, absorbable components. This includes both mechanical digestion (chewing and churning) and chemical digestion (enzymatic breakdown).<br /> - **Absorption:** Nutrients from digested food are absorbed into the bloodstream primarily in the small intestine.<br /> - **Excretion:** Elimination of indigestible substances and waste products as feces.<br /><br />2. **Parts of the Small Intestine:**<br /> - **Duodenum:** The first section where most chemical digestion occurs.<br /> - **Jejunum:** The middle section where absorption of nutrients continues.<br /> - **Ileum:** The final section that absorbs remaining nutrients and passes the residue to the large intestine.<br /><br />3. **Parts of the Stomach:**<br /> - **Cardia:** The area where food enters from the esophagus.<br /> - **Fundus:** The upper curved part of the stomach.<br /> - **Body (Corpus):** The main central region of the stomach.<br /> - **Antrum:** The lower portion that 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 Ileum:**<br /> - The ileum is responsible for absorbing vitamin B12, bile salts, and any remaining nutrients not absorbed by the jejunum. It also plays a role in immune function by containing Peyer's patches, which help protect against pathogens.<br /><br />5. **Function of the Gallbladder:**<br /> - The gallbladder stores and concentrates bile produced by the liver. During digestion, particularly after eating fatty foods, the gallbladder releases bile into the small intestine to aid in the emulsification and digestion of fats.<br /><br />If you have any more questions or need further clarification, feel free to ask!
