Homeostasis is the maintenance of the relatively constant physiological state of the internal environment‚ the biological term meaning ‘same state’‚ is the control of the body’s internal conditions despite fluctuations in the external environment. Blood glucose refers to the sugar that is transported through the bloodstream to supply energy to all the cells in our bodies. Cells in the body need glucose for respiration through mitochondria‚ which produces ATP- the energy source for all processes of

Thermoregulation homeostatic control system Homeostasis is a mechanism which allows humans to maintain a stable internal environment despite fluctuations in the outside environment. It involves a control system that regulates body temperature‚ blood pressure‚ osmotic balance and levels of blood glucose. Thermoregulation is the body’s ability to maintain a specific temperature (36.7 degrees) despite a rise or drop in temperature in the outside environment. If the human body temperature drops below

pathogens.” (CITE) Internal body temperature is a negative feedback mechanism‚ implying that the body responding will represent any adjustment in the internal body temperature outside the ordinary homeostatic range‚ whether the temperature will increase or decrease. In spite of the fact that there is a set homeostatic range for temperature‚ under ordinary conditions the human body is continually fluctuating inside the set range. This implies it is never at a steady perpetual body temperature. Many components

that once a plant reaches a certain acidity within its own body the growth will start to decline. This decline in growth could be due to the fact that a more acidic environment causes the plant to react to try and bring the plant to its desired homeostatic pH. The extra energy expended during trying to reach a certain desired plant pH caused a decline in growth because of how the energy was refocused on homeostasis.

body is a wonderfully working machine. Homeostasis relates greatly to the “set point theory”. The “set point theory” is explained with the use of homeostasis. “The capacity to compensate for either inadequate or excess food intake reflects the homeostatic system in action. The theory (of “set point theory”) is that if I lose weight‚ my body tries to get it back‚ slowing down my metabolism until I return to my predetermined set point” (Kessler‚ 2009‚ pg. 22). The "set point theory" has a way of explaining

term homeostasis was first coined by Walter Cannon in 1929 to literally mean ‘steady state’. It describes the dynamic equilibrium by which internal constancy is maintained within set limits by regulation and control. There are many examples of homeostatic control throughout the human body and in other living organisms‚ such as pH‚ pressure‚ and temperature. A concept important to homeostasis is the process of feedback circuits; involving a receptor‚ an effector‚ and a control centre. A receptor
