In order for the Human Body to maintain balance within its internal environment or return systems to functioning within a normal range, it must manage a multitude of highly complex interactions in order to deal with external changes that are optimal for survival. The organs that help maintain homeostasis are the liver, the kidneys, and the brain through hypothalamus, the autonomic nervous system and the endocrine system. The main function of the liver is to metabolize toxic substance as well as stabilising carbohydrate metabolism. The kidneys are responsible for a number of things. They regulate blood water levels, re-absorb substances into the blood, maintain salt and ion levels in the blood, regulate blood pH, and excrete urea and other wastes, however, there are many factors that can disrupt this process resulting in homeostatic imbalance which may cause disease or death. Factors that need to be carefully controlled are body temperature, water content, carbon dioxide level, and blood sugar level. It is crucial to ensure that these factors are maintained throughout homeostasis. A major factor that affects homeostasis, in general, is water and salt balance.
