Homeostasis refers to maintaining the constant internal body conditions and mostly use the feedback loops to counteract any deviations from the narrow physiological range of several variants such as body temperature, blood glucose levels, etc.
For example, the human body maintains the internal body temperature around 37 degrees Celsius irrespective of the temperature of the surroundings.
When the body temperature rises above the standard range, the secretion of sweat and its evaporation to create the cooling effect is one of the several mechanisms that serve to lower down the body temperature.
Likewise, when the body temperature falls below the normal physiological range, increased heat production and prevention of heat loss are triggered by hypothalamus via autonomic nerve system to increase the body temperature again.
Eukaryotic cells contain several organelles it has: Mitochondria, chloroplasts, the endoplasmic reticulum, the golgi apparatus, and lysosomes. These organelles performs specific function critical to the cell's survival. <span />
