  MODULE II
  
  DIGESTIVE SYSTEM
  
  Mechanical phenomena of digestion: motility of the gastrointestinal tract: peristalsis; rhythmic segmentation; tonic contraction. Swallowing. Gastric motility. Intestinal motility: intestinuo small intestine, large intestine, rectum. Bowel control. Smooth muscle of the wall of the digestive tract. Mechanisms of motility.
  Secretory phenomena of digestion: saliva and salivary glands; gastric juice; gastric mucosal barrier; pancreatic juice; bile; intestinal mucus; Control of secretions.
  Pancreas: structure and function (exocrine and endocrine).
  Liver: structure of the lobules; hepatic circulation. Functions of the liver.
  Digestion and absorption of food (carbohydrates, proteins, lipids). Absorption of vitamins and minerals.
  Gastrointestinal hormones: gastrin, secretin, cholecystokinin, GIP, somatostatin, motilin, VIP.
  
  Control of food intake
  Nerve centers for the regulation of food intake. Factors that regulate the amount of food intake.
  
  ADJUSTMENT OF THE ASSUMPTION OF WATER
  Water balance: intake and elimination of water. Routes of elimination of water. Hormones regulating fluid and electrolyte balance: vasopressin, renin, angiotensin, aldosterone. Nervous structures delegated to the regulation of water: thirst center.
  
  THE ENDOCRINE SYSTEM
  Homeostasis is guaranteed by the intercellular communication. Classes of hormones. Hormone secretion. Mechanisms of action of hormones. Control of endocrine activity. Pituitary gland (adeno-and neurohypophysis): hormones secreted and their functions. Thyroid hormone secretions and their functions. Adrenal (cortex and medulla): secreted hormones and their functions. Pancreas secreted hormones and their functions.
