Together, these two systems are primarily responsible for maintaining homeostasis in the body. In the human body, two major organ systems participate in relatively “long distance” communication: the nervous system and the endocrine system. Identify the major organs and tissues of the endocrine system and their location in the bodyĬommunication is a process in which a sender transmits signals to one or more receivers to control and coordinate actions.Distinguish the types of intercellular communication, their importance, mechanisms, and effects.By the end of this section, you will be able to:
