  1. Dissection of the Fetal Pig (Sus scrofa) place where latex paint was injected into the jugular vein and the carotid artery side view 1.umbilical cord- Connection to placenta

  2. peritoneum/umb arts/liver 2.liver-produces bile, etc peritoneum (smooth inner lining of abdominal cavity) umbilical arteries

  3. liver/spleen/stomach separate lobes of the liver stomach 3. spleen- Breaks down old rbc’s

  4. intestine sm/lge 5. large intestine- Re-absorbs water and compacts feces 4. small intestine- Digests and absorbs nutrients

  5. gall bladder 6. gall bladder- Stores bile (fat detergent) bile duct (to duodenum)

  6. bile duct (closeup) gall bladder bile duct

  7. stomach/duodenum/spleen 7.stomach- Begins protein digestion spleen duodenum

  8. pyloric sphincter/bile duct bile duct (to duodenum) 8. pyloric sphincter (=valve) Controls flow of chime into duodenum 9. Pancreas- Secretes enzymes And makes insulin

  9. pancreas duodenum stomach pancreas spleen

  10. rectum 10. rectum– Feces stored before being expelled

  11. abdominal aorta (zoom) 12. inferior vena cava- Returns blood to heart from lower extremities 11. aorta- Biggest artery of body

  12. kidneys 13. kidneys- Filter wastes (urea) from blood ureter (tube to urinary bladder)

  13. diaphragm 14. Diaphragm- Separates chest cavity from abdomen. Main muscle of respiration.

  14. larynx larynx trachea (=windpipe)

  15. trachea 16. trachea- “windpipe” Allows O2 and CO2 to move from throat to lungs

  16. lungs 17. lungs- Bring oxygen into bloodstream, Excrete CO2 into air right lung left lung

  17. pericardial sac 18. heart- Pumps blood through blood vessels pericardial sac (encloses the heart)

  18. heart ventricles 20. left ventricle (pumps blood to the entire body – except the lungs) 19. right ventricle (pumps blood to lungs)

  19. right atrium 21. right atrium (receives de-oxygenated blood from the body)

  20. left atrium 22. left atrium (receives oxygenated blood from the lungs)

  21. pulmonary artery right atrium left atrium 23. pulmonary artery (sends de-oxygenated blood to the lungs)

  22. aorta right lung pulmonary artery coronary artery 24. aorta (sends oxygenated blood to the entire body under high pressure)
