Chemical Coordination and Integration
Solution:
The thymus gland is a lobular structure located
between lungs behind sternum on the ventral side of
aorta. The thymus plays a major role in the

degenerated in old individuals resulting in a decreased
production of thymosing. As a result, the immune
responses of old persons become weak.
