    Study Notes

    Digestive System Functions

    • The stomach is the organ responsible for mechanical digestion by breaking up food through muscular contractions and mixing it with digestive juices.
    • Salivary amylase is the enzyme in saliva that digests starch into maltose, initiating carbohydrate digestion in the mouth.

    Accessory Digestive Organs

    • Accessory digestive organs, including the liver, pancreas, and gallbladder, primarily function to produce and store digestive enzymes and substances, facilitating digestion and nutrient absorption.

    Gastrointestinal Tract and Propulsion

    • The esophagus and intestines are parts of the gastrointestinal tract where propulsion of food occurs through peristalsis, a series of wave-like muscle contractions that move food along the digestive tract.

    Absorption of Nutrients

    • The majority of nutrient absorption takes place in the small intestine, where digested products are absorbed into the bloodstream through specialized structures called villi and microvilli.
