ATI TEAS SCIENCE REVIEW
BODILY ORGANS AND SYSTEMS
ATI TEAS SCIENCE – BODILY ORGANS AND BODILY SYSTEMS
Questions related to the Bodily Organs and Systems will test yourknowledge of structures and functions within the ten human organsystems that are essential to life. You may also be tested on vocabularyterms related to your understanding of anatomy. You must understandthese vital body systems when caring for patient’s co-morbidities.
Please note that the ATI TEAS will only cover basic knowledge ofbodily organs and systems. More in-depth knowledge will be coveredin our Anatomy and Physiology Series.
Let’s get started on understanding how the bodily organs and systemsare important on the ATI TEAS.

ATI TEAS SCIENCE – BODILY ORGANS AND BODILY SYSTEMS
THE ENDOCRINE SYSTEMThe endocrine system works closely with the nervous system to maintain balance in the body by regulating the glands and hormone production.
Hormones are chemical messengers produced by the endocrine glandsin the body. These glands secrete information to different parts of the body through the bloodstream to target cells (cells they are meant to act upon).
Hormones are transmitted to maintain homeostasis in the body. If the gland producing the hormone receives feedback from a system, the gland can respond appropriately by increasing or decreasing the production of that hormone.

THE ENDOCRINE SYSTEM
There are several different endocrine glands located throughout the body.
• The pituitary gland is controlled by the hypothalamus in the brain and is responsible for much of the system’s regulatory function.
• One particularly important hormone it produces is growth hormone.
• The pineal gland is responsible for the hormone melatonin, which influences the sleep cycle.
