    Study Notes

    Digestive System Functions

    • Bile is produced by the liver to aid in the absorption of fats.
    • The pyloric sphincter regulates the flow of digested food from the stomach to the small intestine.
    • Most digestion of carbohydrates, proteins, and fats occurs in the small intestine.
    • The pancreas produces digestive enzymes and bicarbonate to neutralize stomach acid, facilitating digestion in the small intestine.

    Large Intestine and Feces

    • In the large intestine, water is reabsorbed, and waste material is compacted and prepared for excretion.
    • Feces are primarily composed of undigested food, bacteria, and waste products.

    Functions of Teeth and Pharynx

    • Teeth function mechanically by chewing food, breaking it down into smaller pieces for easier digestion.
    • The pharynx plays a critical role in swallowing by guiding food from the mouth to the esophagus.

    Esophagus and Mucus

    • The esophagus transports food from the throat to the stomach through peristalsis (muscular contractions).
    • Mucus in the stomach protects the lining from gastric acid and aids in food movement.

    Epiglottis and Choking

    • The epiglottis prevents food from entering the trachea, ensuring it directs food to the esophagus.
    • If choking occurs due to epiglottis failure, the Heimlich maneuver is a common treatment.

    Organs and Structure

    • The liver is the largest glandular organ in the body.
    • The small intestine consists of three parts: the duodenum, jejunum, and ileum.

    Urinary System

    • The urethra facilitates the expulsion of urine from the bladder to the outside of the body.
    • An adult bladder can normally hold about 400-600 mL of urine.
    • Blood pressure forces plasma into the nephron via a process called glomerular filtration.

    Kidney Health and Dialysis

    • If the kidneys fail to function properly, dialysis can be used to artificially filter waste from the blood, replacing kidney function.
    • Dialysis works by using a machine to filter waste products and excess fluid from the blood, which are then excreted instead of being processed by the kidneys.
