🔑 Key Concepts & Definitions

  • Digestive Tract (Gastrointestinal Tract): A continuous muscular tube extending from the mouth to the anus, responsible for digestion, absorption, and elimination of food.
  • Accessory Organs: Structures that assist digestion but are not part of the GI tract, including the liver, pancreas, and gallbladder.
  • Mucosa: The innermost layer of the GI tract, consisting of epithelial tissue that secretes mucus and enzymes, and absorbs nutrients.
  • Peristalsis: Involuntary, wave-like muscle contractions that propel food through the digestive tract.
  • Chyme: The semi-liquid, partially digested food mass formed in the stomach, ready for further digestion in the small intestine.
  • Villi: Tiny, finger-like projections lining the small intestine that increase surface area for nutrient absorption.
