  • STAGES OF DIGESTION
    2. Stomach
    • Hydrochloric acid - these are known as gastric juices
    • Pepsin - enzymes found in the stomach
  • STAGES OF DIGESTION
    3. Duodenum
    • Pancreatic Amylase
    • Pancreatic Lipase
    • Trypsin
  • STAGES OF DIGESTION
    4. Small Intestine
    • Lactase - used to breakdown lactose
    • Maltase - used to breakdown maltose
    • Sucrase-isomaltase
    • Peptidase
  • 3 Stages of Gastric Secretion
    1. Cephalic Phase - Thinking of what to eat
    • Vagus Nerve - nerve that stimulates gastric juices.
  • 3 Stages of Gastric Secretion
    2. Gastric Phase - inside the stomach
    • Vagus
    • Gastrin - a hormone that produces gastric juices or acid
  • 3 Stages of Gastric Secretion
    3. Intestinal Phase - about to go to the small intestine
    • Gastrin
    • Secretin - stimulates the pancreas to release a bi-carbonate which regulates acids
    • CCK-PZ (Cholecystokinin-Pancreozymins) - from pancreas which stimulates the gallbladder to release bile
    • Somatostatin - regulates gastric juice and prevents it from being too excessive.
    • GIP (Gastric Inhibitory Polypeptide) - stimulates the pancreas to produce insulin
    • VIP (Vasoactive Intestinal Polypeptide) - is responsible for regulation of smooth muscle activity
  • Parts of the small intestine (3):
    1. Duodenum - the starting point
    2. Jejunum - contains most of the blood vessels
    3. Ileum - the last part
  • Liver responsibilities include (7):
    1. Metabolism - converts excess glucose into glycogen for storage
    2. Digestion - produces bile which breaks down fats
    3. Immunity - the liver stores iron which is mainly used in hemoglobin for immunity.
    4. Detoxification - the liver filters blood.
    5. Vitamin storage - stores vitamins|
    6. Blood clotting - creates substances that help blood clot after injury.
    7. Albumin production - albumin is a protein that helps carry hormones throughout the body.
  • Pancreas (2):
    1. Exocrine - produces enzymes that breaks down fats
    2. Endocrine - produces insulin and glucagon
