    Study Notes

    Alimentary Canal

    • The alimentary canal, also known as the digestive tract, is a long tube that starts at the mouth and ends at the anus.
    • It is responsible for the digestion and absorption of food.

    Mouth

    • The mouth is the first part of the alimentary canal.
    • Food is chewed and mixed with saliva.
    • Saliva contains the enzyme salivary amylase which helps break down starch into simpler sugars like maltose.
    • The tongue helps mix the food with saliva.

    Esophagus

    • The esophagus is a muscular tube that connects the mouth to the stomach.
    • Peristalsis, a wave-like muscular contraction, moves food down the esophagus.

    Stomach

    • The stomach is a muscular pouch that stores, mixes, and churns food with gastric juice.
    • Gastric juice contains hydrochloric acid and enzymes.
    • Gastric glands in the stomach wall secrete gastric juice.
    • The stomach breaks down large food molecules into smaller, absorbable ones.

    Small Intestine

    • The small intestine is divided into three segments: duodenum, jejunum, and ileum.
    • Enzymes from the liver and pancreas continue breaking down food in the small intestine.
    • The liver produces bile, which helps digest fats.
    • The pancreas produces pancreatic juice containing enzymes for various food groups.
    • The small intestine's inner wall has villi, finger-like projections that absorb digested food and water.

    Liver

    • The liver is the largest gland in the body.
    • It secretes bile, a digestive fluid that helps break down fats.

    Pancreas

    • The pancreas secretes pancreatic juice, which contains enzymes that help digest carbohydrates, proteins, and fats.

    Large Intestine

    • The large intestine absorbs water and stores waste material.
    • The large intestine leads to the rectum, which continues to absorb water.
    • Feces are eliminated through the anus (defecation).
