Explanation
The posterior lobe of the pituitary stores and releases two hormones called oxytocin and vasopressin. These hormones are actually produced by the neurosecretory cells in the hypothalamus and stand in the terminals of their axons that pass into the posterior lobe through a stalk. They are released via the posterior lobe when required. Vasopressin is also called the antidiuretic hormone (ADH). It decreases the loss of water in the urine by increasing reabsorption of water in the distal convoluted tubules, collecting tubules and collecting ducts in the kidneys.

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.
