Essay On Homeostasis

Homeostasis can be defined as the ability or tendency of an organism to maintain its stability. If an organism does not maintain homeostasis it will die. Dynamic equilibrium is what happens when the organism adjusts to maintain a constantly balanced internal environment. Dynamic equilibrium is caused by the organs inside humans and other animals fluctuating between increasing or decreasing their function to maintain homeostasis. The way these organs react is known as a response, and the response is reacting to a stimulus. A stimulus is something that affects the way organisms function. The body maintains homeostasis by working with the nervous system. The nervous system releases hormones which signal the cells or organs to decrease or increase their function.
There are many things that impact whether an organism maintains homeostasis or not. Some include: body temperature, water balance, blood sugar concentration, blood pressure and blood pH, and to maintain homeostasis must be regulated. These functions are controlled by negative feedback mechanisms. Feedback mechanisms are mechanisms that control and regulate processes and internal conditions in an organism. They respond to any stimulus

Other terrestrial animals maintain homeostasis slightly different to humans. For example, in regulating body heat for dogs, they can’t secrete sweat so they pant to cool down. Each living organism will maintain homeostasis slightly different to each other. For example, plants compared to animals. Plants maintain homeostasis by using their stomata, as it is used for gas exchange. These are the pores on the underside of the leaf. The cells are loosely packed and gases move though the plant in air spaces. The gases are exchanged with the atmosphere and the stomata also helps with transpiration, which maintains the plant’s internal temperature (Socratic.org, 2017). Figure 6 to the left displays
