    Study Notes

    Overview of the Digestive System

    • The digestive system is a complex series of organs that work together to break down food into nutrients the body can absorb and use for energy and growth.
    • It involves mechanical and chemical processes.

    Stages of Digestion

    • Ingestion: The process of taking food into the mouth. This initiates the digestive process.
    • Mechanical Digestion: The physical breakdown of food. This happens through chewing (mastication) and churning in the stomach. It increases the surface area for chemical digestion.
    • Chemical Digestion: Breaks down complex food molecules into simpler absorbable nutrients. Enzymes play a major role in this process. Enzymes are proteins that speed up chemical reactions.
    • Absorption: The transfer of digested nutrients from the digestive tract into the bloodstream. This mainly occurs in the small intestine.
    • Elimination: The removal of undigested food and waste products from the body. This happens through the large intestine and the anus.

    Organs and their Functions

    • Mouth: Mechanical digestion (chewing) begins here, and salivary amylase, an enzyme, starts the chemical breakdown of carbohydrates.
    • Esophagus: A muscular tube that transports food from the mouth to the stomach. Peristalsis, wave-like contractions of muscles, propels food through the esophagus.
    • Stomach: A muscular sac that mixes food with stomach acid (Hydrochloric acid) and enzymes (pepsin) to break down proteins. The stomach also stores food temporarily.
    • Small Intestine: The primary site of nutrient absorption. It has villi and microvilli, increasing the surface area for absorption.
    • Pancreas: Produces enzymes (amylase, lipase, protease) that help break down carbohydrates, fats, and proteins in the small intestine. The pancreas also produces bicarbonate to neutralize acidic chyme coming from the stomach.
    • Liver: Produces bile, which helps digest fats. Bile is stored in the gallbladder and released into the small intestine. The liver also processes nutrients absorbed into the bloodstream. It plays a crucial role in detoxification.
    • Large Intestine: Absorbs water and electrolytes from undigested food. It also forms and stores feces. The colon and rectum are parts of the large intestine, playing a vital role in the elimination process.
    • Rectum: Stores feces until elimination.
    • Anus: The opening through which feces are expelled from the body.

    Key Digestive Enzymes

    • Amylase: Breaks down carbohydrates into simpler sugars.
    • Lipase: Breaks down fats into fatty acids and glycerol.
    • Pepsin: Breaks down proteins into smaller peptides.

    Digestive Disorders

    • Heartburn: A burning sensation in the chest caused by acid reflux.
    • Constipation: Difficulty in emptying bowels.
    • Diarrhea: Frequent passage of loose, watery stools.
    • Ulcers: Open sores in the lining of the digestive tract.
    • Crohn's disease and ulcerative colitis: Inflammatory bowel diseases (IBD) affecting the different parts of the digestive tract

    Regulation of Digestion

    • The nervous system and hormones regulate the different stages of digestion.
    • Hormones released by the stomach and small intestine control the release of digestive juices and the movement of food through the digestive system.

    Importance of Proper Digestion

    • Proper digestion is crucial for providing the body with essential nutrients needed for growth, repair, and overall health.
    • Malnutrition can result from improper digestion.
