Biga, Sierra Dawson, Amy Harwell, Robin Hopkins, Joel Kaufmann, Mike LeMaster, Philip Matern, Katie Morrison-Graham, Devon Quick & Jon Runyeon, Creative Commons Attribution-ShareAlike 4.0 International License, List the components of a homeostatically controlled system, Discuss the role of homeostasis in the human body, Contrast negative and positive feedback, giving one physiologic example of each mechanism. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. The control center compares the value to the normal range. When blood pressure is consistently too high it puts huge strain on the heart and blood vessels, ramping up risk for stroke and heart attack. The maintenance of homeostasis by negative feedback goes on throughout the body at all times and an understanding of negative feedback is thus fundamental to an understanding of human physiology. Homeostasis - Anatomy & Physiology - University Of Hawaii For instance, when you exercise, your muscles increase heat production, nudging your body temperature upward. Here, a single clotting factor results in the activation of many more clotting factors. Homeostasis | Definition, Function, Examples, & Facts So the pressure essentially causes contractions in the uterus which stimulate nerve impulses in the brain to release more oxytocin, which further increase the pressure of the fetus' head. Thus, understanding the factors affecting vacuole function is important for the identification of new drug targets needed in response to the world's increasing levels of invasive infections and the growing issue of fungal .
