Digestive System

Code 14227
Year 2
Semester A1
ECTS Credits 7
Workload OT(46H)/PL(8H)/S(6H)
Scientific area Morphological and Functional Sciences
Entry requirements Basic knowledge of cell biology and biochemistry Knowledge of the central nervous system
Learning outcomes Describe the anatomy and anatomical relationships, embryology and histology of the organs of the digestive tract and annex glands, the anatomical structure and arrangement of the anterolateral abdominal wall and the parietal and visceral peritoneum.
Relate the histology of the organs of the digestive system with the functions they perform and explain the importance and regulatory mechanisms of these functions.
Explain the processes of digestion and absorption of the main nutrients and the importance of morphophysiological adaptations of the gastrointestinal tract in these processes.
Explain the regulatory mechanisms of intestinal transit along the entire gastrointestinal tract and its importance for the digestion and absorption of nutrients.
Skills:
Develop the ability to the oral presentation of complex mechanisms, and to apply knowledge in response to concrete problems.
Develop the ability to work in a team.
Identify the organs of the digestive tract under an optical microscope.
Syllabus Anatomy, embryology, histology of the mouth, tongue, pharynx, esophagus, stomach, duodenum, jejunum, ileum, colon, rectum, anal canal and glands/annex organs: salivary glands, liver, gallbladder and pancreas.
Composition of secretions from the organs of the digestive system: salivary, gastric, pancreatic secretion, bile production, control of its secretion and relevance in the digestion of nutrients.
Liver functions: elimination of viruses and bacteria, metabolism and storage of nutrients, production of bile, regulation of blood volume, detoxification, production of plasma proteins.
Mechanisms of digestion and absorption of proteins, lipids and carbohydrates.
Intestinal transit and its regulation by the enteric nervous system, hormones and local mediators: swallowing, gastric emptying, small bowel transit and the importance of segmental contractions, colonic transit and mass movements, regulation of the defecation process
