14. 
Duodenum
 
Completes chemical digestion and begins nutrient absorption
 
15. 
Jejuno-ileum
 
Nutrient absorption
 
16. 
Pancreas
 
Secretes digestive enzymes into small intestine and insulin and glucagon into the blood stream.
 
17. 
Spleen
 
Filters blood, removing red blood cells
 
18. 
Mesentary
 
Membrane supporting the coils and blood vessels.
 
19. 
Large intestine
 
Reabsorbs water and ions
 
20. 
Cecum
 
Blind sac at the beginning of the large intestine; fermentation of cellulose
 
21. 
Rectum
 
Water reabsorption and fecal storage until elimination.
 
22. 
Right atrium
 
Receives blood from body and pumps to right ventricle.
 
23. 
Left atrium
 
Receives oxygenated blood from lungs and pumps to left ventricle
 
24. 
Right ventricle
 
Receives blood from right atrium and pumps to lungs to be oxygenated
 
25. 
Left ventricle
 
Receives oxygenated blood from the left atrium and pumps to the body
 
26. 
Coronary artery and vein
 
Supplies blood to heart tissue
 
27. 
Superior vena cava
 
Carries oxygen-poor blood from the head, neck, pectoral appendages and cranial part of the chest to the right atrium
 
28. 
Inferior vena cava
 
Carries oxygen poor blood from the caudal parts of the body to the right atrium.
 
29. 
Pulmonary trunk
 
Transports deoxygenated blood from right ventricle to lungs
 
30. 
Pulmonary veins
 
Transports oxygenated blood from the lungs to the left atria
 
31. 
Aorta
 
Transports oxygenated blood from left ventricle to the body
 
32. 
Tricuspid valve
 
Prevents backflow from the right ventricle into the right atria
 
33. 
Bicuspid valve
 
Prevents back flow of oxygen rich blood from the left ventricle into the left atria
 
34. 
Aortic valve
 
Prevents backflow of blood from the aorta to the left ventricle
 
35. 
Pulmonary semilunar valve
 
Prevents backflow of blood from pulmonary trunk (artery) into the right ventricle
 
36. 
Umbilical vein and artery
 
Circulates deoxygenated nutrient poor blood back to mother and brings oxygenated nutrient rich blood from the mother to the developing fetus
 
37.
