Another fun book about the human body by the same team who gave us The Museum of Odd Body Leftovers a couple years ago. I love the table of contents: a map of the Gland Factory so we know where to begin our tour. First stop: the mouth machine. You may want to put on a poncho and a hardhat, because things can get messy on the factory floor. The Mouth Machine has teeth that can crush you dead, and saliva glands that could drown you in spit. 

Make sure you hold on tight as we climb the ladder up to … the nostrils and inner nose. Hmmm, looks like the floor supervisor is doing a safety inspection of the nasal glands…

 After a quick stop at the eyes we get to Main Control in the hypothalamus. No gloop here! This is a messenger gland, a control station that sends and receives a continuous stream of chemicals from endocrine glands. Together they coordinate the body’s vital systems: circulation, digestion, sleep, metabolism, temperature control, and more. These important messages are sent through the bloodstream, similar to rolled up notes stuffed in a bottle and sealed and tossed into a stream. Unlike notes in a bottle, the messages are read and responded to. 

Upon receiving a message, the worker in charge runs it through the hormone decoder machine and then releases the appropriate response hormone from the hormone storehouse. At least that’s how it works in the gland factory. In real life it’s all about body chemistry and receptor cells that ensure the correct hormone message connects with the correct body part.

The tour exits through the waxy ear holes, but before you go, please fill out a visitor survey. (And leave your hardhat and protective gear.) Back matter includes a glossary, suggestions for further reading, and an index.

Thanks for dropping by today. On Monday we'll be hanging out at Marvelous Middle Grade Monday with other  bloggers. It's over at Greg Pattridge's blog, Always in the Middle, so hop over to see what other people are reading. Review copy provided by the publisher.
