Ventral view of poultry kidneys showing

• adrenal glands (1),
• aorta (2),
• vena cava (3),
• renal arteries (4),
• renal veins (5),
• kidney on right side (7),
• coprodeum (8),
• urodeum (9),
• proctodeum (10),
• whole cloaca (11)

However, in all honesty, anyone who peers up a chicken'c cloaca is not likely to see much difference between (8), (9) and (10) - it's one of those bits of terminology that is more theoretical than practical!
