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.
The nervous and endocrine systems control homeostasis
Both the nervous and endocrine systems maintain homeostasis. They work together to monitor and adjust as necessary.
There are many endocrine systems. An endocrine system is one where a gland excretes substances internally or to a surface such as the skin. Both salivary glands and sweat glands are two such systems. It may seem picky to make this distinction but each system uses its own feedback to achieve homeostasis (equilibrium). There are several types off feedback loop such as "mechanical circuits" (sweat cooling skin to slow this process) or by nervous or hormonal systems. edit: Neither salivary glands nor sweat glands are apart of the endocrine system. Both are exocrine.

feedback loops maintain balance and homeostasis.
YES, + feedback systems enhance or intensify the stimulus. Eg. of a + feedback system = childbirth

Thermoregulation relies on negative feedback. Negative feedback works to return a system to homeostasis by reducing a stimulus, such as a change in temperature. By contrast, positive feedback systems amplify or speed up a response.
