The endocrine system consists of the glands in the body that produce hormones, which are chemical messengers that travel through the blood to the target cells upon which they act. Hormones regulate the body's metabolism, development, sexual function, and mood among other things. The endocrine system is one of the body's main communication systems along with the nervous system.
For the MCAT, the endocrine system presents one of the biggest memory challenges from within physiology for the exam. Endocrine function is a long-standing favorite of MCAT writers. Ideally, a person should to begin studying the endocrine glands and hormones as early as possible in MCAT review (Several Knowledge Mapping tasks begin this work in earlier modules.) Don't let the final phase of review turn into one big physiology cram session. Start earlier than Module 12 to review the factual material within the endocrine system and the other topics of physiology.
