Explain why the endocrine system is the most important in maintaining homeostasis. (iii) pH is our digestive system: (HCl) Hydrochloric acid is produced by our stomach that helps in the digestion of food. In many living organisms, including in humans, the evaporation of sweat, which is 90 percent water, allows the organism to cool so that homeostasis of body temperature can be maintained. All living things are water-based systems, which means that they depend heavily on aqueous equilibria, especially acid-base equilibria. Homeostasis is order. Homeostasis is the capacity of living organisms to maintain their internal stability of bodies, as appropriate to the temperature and pH (acidity and alkalinity balance), through the exchange of matter and energy with the environment. Osmoregulation is the process of maintaining salt and water balance (osmotic balance) across membranes within the body. High pH may also increase the toxicity of other substances. Oxytocin increases uterine contractions, and thus pressure on the cervix. Why it is important that pepsin functions at a low pH? 6 Where does the word homeostasis come from in Greek? Water is essential to life, thus osmoregulation is vital to the health and well-being of humans and other animals. In the behavioral sciences, however, the concept of homeostasis is acknowledged, but it rarely fulfils a prominent role in actual analyses. Extreme pH levels can denature enzymes completely disrupting their function.
