The two organ systems that regulate and maintain homeostasis are the

The correct answer is: the nervous system and the endocrine system.

Explanation:

Homeostasis is the state in which the body maintains itself in order to operate accordingly. If homeostasis fails, diseases occur. There are many factors that are important to maintain in a range of normality, like body temperature, pH, and ion concentration.

In order to maintain homeostasis, the nervous system and the endocrine system intervene to regulate the factors mentioned above.

The nervous system makes use of neurotransmitters, which are molecules that are transmitted through nervous impulses and that carry information that is capable of exciting or inhibiting different cells and processes.

The endocrine system maintains homeostasis by producing and transporting hormones (made by endocrine glands) that reach specific cells and trigger specific reactions.

For example, when the body is losing too much water due to heavy exercise, the pituitary gland produces the hormone ADH, which will act on the kidney to produce reabsorption of water that will also concentrate the urine.

The Endocrine system and Nervous system

Explanation:

Homeostasis is the process of maintaining the internal environment of the body. The body regulates it's internal environment using the endocrine and nervous systems with various organs involved such as, lungs, kidneys, skin, pancreas. Temperature, blood sugar levels, oxygen and carbon iv oxide concentration, urea and other metabolic waste are examples of substances that the body needs to keep in control. The endocrine system is the system which are collection of glands that produce hormones needed for various regulatory purposes. This system consists of pituitary, thyroid, parathyroid, adrenal glands, pancreas. The nervous system responses to the various stimulus by causing the endocrine system to produce it's hormones for the appropriate response. For instance, when the level of water in the bloodstream becomes low, the hypothalamus (nervous system) in the brain release an hormone called antidiuretic hormone (ADH), the ADH stimulates th kidneys to absorb water through water channels and vice versa when there is excess water in the bloodstream.
