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 your knowledge of structures and functions within the ten human organ systems that are essential to life. You may also be tested on vocabulary terms related to your understanding of anatomy. You must understand these vital body systems when caring for patient’s co-morbidities. Please note that the ATI TEAS will only cover basic knowledge of bodily organs and systems. More in-depth knowledge will be covered in our Anatomy and Physiology Series. Let’s get started on understanding how the bodily organs and systems are important on the ATI TEAS.

ATI TEAS SCIENCE – BODILY ORGANS AND BODILY SYSTEMS THE ENDOCRINE SYSTEM The 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 glands in 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.

ATI TEAS SCIENCE – BODILY ORGANS AND BODILY SYSTEMS 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.
