In fact the Nervous system can transmit signals at speeds of 100 meters (328 feet) per second.

The Endocrine system is the gland compilation that produces hormones that, among other stuff, control metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood.

This system contains two important organs, hypothalamus (hy·po·thal·a·mus)...

...and pineal body (pin·e·al) that are important to the function of the system.

Good job you two, that's correct! And now for an interesting fact...
