Lastly the effector directs some sort of response.The hypothalamus is a section of the brain . Two examples of variables that change are body temperature and blood glucose. (Figure 1.3.2a). If homeostasis is successful, life continues; if unsuccessful, disaster or death ensues. Begin typing your search term above and press enter to search. Regardless of the variable being kept within its normal range, maintaining homeostasis requires at least four interacting components: stimulus, sensor, control center, and effector. It is an organism's ability to keep a constant internal environment. This cycle includes four components: Sensors or detectors, which recognize the deviation Transmission of this message to a control center can someone please tell me which organ in the body controls homeostasis? The Tissue Level of Organization, Chapter 6. Since this is very necessary and important, a positive feedback loops is run: the substance that pushes the fetus' head towards the cervix, oxytocin, is released as a cause of contractions from the uterus, which are themselves a cause of pressure from the fetus' head on the cervix. This website uses cookies to improve your experience while you navigate through the website. Explain why contraction of the diaphragm causes the lungs to fill with air. Oxytocin causes stronger contractions of the smooth muscles in of the uterus (the effectors), pushing the baby further down the birth canal. Homeostasis is regulated by negative feedback loops and, much less frequently, by positive feedback loops. Homeostasis is a key concept in understanding how our body works.
