Homeostasis is the balancing act of the body. Everything should remain in balance. Negative feedback performs this service. For instance, if the core body temperature goes above a "norm" of 98.6, the body will bring the temp down by taking superficial blood vessels close to the surface causing "flushing" and perspiration will occur which cools the skin, in turn cooling the blood in the superficial vessels, and eventually cooling the core body temperature. If the core temp is cooler than norm, the superficial blood vessels will retreat causing the skin to become pale, goose pimples might occur, and in the extreme shivering will cause an increase of heat production through the involuntary contraction of skeletal muscles.
The option that does NOT control homeostasis is positive feedback such as the uterine contractions of childbirth. The contractions will continue to build in strength and do not stop until the child is born. There is no give-and-take in positive feedback, which is what you find in the negative format. Other positive feedback examples are blood clotting and lactation.
What else can I help you with?
What of the negative feedback systems that control homeostasis?
Negative feedback systems are essential for maintaining homeostasis by detecting deviations from the set point and activating mechanisms to reverse them. This ensures stability in biological systems by minimizing fluctuations and maintaining internal balance. Examples include temperature regulation, blood glucose levels, and hormone levels.
How does the body systems maintain homeostasis?
The body systems maintain homeostasis through mechanisms such as temperature regulation, pH balance, and blood glucose control. This is achieved through feedback loops that involve sensors, control centers, and effectors to adjust internal conditions as needed. Homeostasis ensures that the body's internal environment remains stable despite external changes.
What are the feedback systems for homeostasis?
The feedback systems for homeostasis typically involve negative feedback loops that help maintain a stable internal environment within the body. These feedback mechanisms involve sensors that detect changes in variables like temperature or blood sugar levels, which then trigger responses to counteract those changes and bring the body back into balance. Examples include the regulation of body temperature through sweating or shivering, or the control of blood sugar levels through the release of insulin or glucagon.
What 2 systems control homeostasis?
The two systems that control homeostasis in the body are the nervous system and the endocrine system. The nervous system helps to detect changes in the internal and external environment, while the endocrine system releases hormones to regulate and maintain a stable internal environment.
The control of homeostasis?
homeostasis is controled in the hypothalamus the thalamus and blood sugar is controlled in the pancreas. The main control centre would be the hypothalamus, monitoring and implementing ideal values to a set point.

What kind of feedback mechanism help maintain homeostasis causing a stimulus to increase?
YES, + feedback systems enhance or intensify the stimulus. Eg. of a + feedback system = childbirth

What is an open loop in control systems?
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
