Explanation
The thymus gland is a small, two-lobed organ that is located in the upper chest, between the lungs, and behind the breastbone (sternum). It is part of the lymphatic system and is responsible for developing T cells, which are a type of white blood cell that plays a key role in the immune system. The thymus is relatively large in infants and children, but it begins to shrink after puberty and is usually quite small in adults.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
