Section 29 -1 “How Organs Communicate” Write everything that is BLACK

29. 1 How Organ Systems Communicate Standards • As a result of the coordinated structures and functions of organ systems, the internal environment of the human body remains relatively stable (homeostatic) despite changes in the outside environment. As a basis for understanding this concept: – B. Students know how the nervous system mediates communication between different parts of the body and the body's interactions with the environment.

29. 1 How Organ Systems Communicate KEY CONCEPT The nervous system and the endocrine system provide the means by which organ systems communicate.

29. 1 How Organ Systems Communicate What does communication mean? • a process by which information is exchanged between individuals through a common system of symbols, signs, or behavior

29. 1 How Organ Systems Communicate The body’s communication systems help maintain homeostasis – remember that? ? Homeostasis is when the body maintains an internal set of conditions to KEEP YOU ALIVE!

29. 1 How Organ Systems Communicate How your body communicates: • A stimulus causes a response • Responses can be chemical, cellular, or behavioral • The nervous and endocrine systems respond to stimuli • Example: – Stimulus = Cold weather – Response = Shivering

29. 1 How Organ Systems Communicate • The nervous system controls thoughts, movement, and emotion • The endocrine system controls growth, development, and digestion

29. 1 How Organ Systems Communicate The nervous and endocrine systems have different methods and rates of communication • The nervous system works quickly, using chemical and electrical signals – interconnected network of cells – signals move through cells – divided into central nervous system (CNS) and nerves peripheral nervous system (PNS) spinal chord

29. 1 How Organ Systems Communicate • The endocrine system works more slowly – only chemical signals – signals move through bloodstream – physically unconnected organs target cell hormone bloodstream receptor not a target cel
