  167. Name the components of the GI tract
    mouth, most of pharynx, oesophagus, stomach, small intestine, large intestine
  168. Name the accessory organs
    salivary glands, liver, gallbladder, pancreas
  169. Describe ingestion
    the process of taking foods and liquids into the mouth
  170. Describe secretion
    of water, acid, enzymes, into the digestive tract (lumen)
  171. Describe mixing and propulsion
    contraction and relaxation of smooth muscle in the walls of the digestive system to mix food and secretions, and to propel material towards the anus
  172. Describe digestion
    mechanical and chemical breakdown of food into molecules small enough to be absorbed
  173. Describe mechanical digestion
    teeth cut and grind food before it is swallowed, then the smooth muscle of the stomach and the small intestines churns the food.
  174. Describe chemical digestion
    large carbohydrates, lipids, proteins and nucleic acid molecules are broken down by enzymes.
  175. Describe absorption
    small molecules broken down by digestion are passed into blood or lymph capillaries through the wall of the digestive tract
  176. Describe defecation
    wastes, indigestible substances, bacteria and  cells leave the body through the anus. Eliminated material is called faeces
  177. What is the main function of the gallbladder?
    Store and concentrate bile
  178. What is chyme?
    mix of gastric juices and the bolus of food
  179. What is the main function of the pancreas?
    Produces and enzyme-rich secretion
  180. List in order the structures through which food passes from the mouth to the anus
    Mouth, pharynx, oesophagus, stomach, duodenum, jejunum, ileum, caecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, anus.

    • 4. Renal vein
    • 5. Abdominal aorta
    • 6. ureter
    • 7. urinary bladder
    • 8. urethra
  187. What are the functions of the urinary system?
    • Regulate composition and volume of blood by filtering it and removing wastes and H ions (pH)
    • To produce hormones - calcitriol and erythropoietin
    • to regulate BP via regulation of blood volume
  188. What are the 8 functions of the kidneys?
    • Regulation of blood ionic composition
    • Regulation of blood pH
    • Regulation of blood volume
    • Regulation of BP
    • Regulation of blood glucose level

    • Production of hormones - calcitriol and erythropoietin
    • Excretion of wastes from metabolic reactions and foreign substances (drugs or toxins)
