Describe Two Examples Of Homeostatic Systems In Humans
Describe two examples of homeostatic systems in humans
The phrase homeostasis originates from the Greek language. “Homeo” defined as “similar” and “stasis” meaning “stable”. Homeostasis is vital for us humans as it maintains equilibrium in the body, which may be caused due to extrinsic changes. Homeostasis happens to sustain the bodies activity, health and functioning. Homeostasis can occur to organs like skin, kidney or liver and it usually contains a system of feedback controls. The body has various sensors; it can detect many physiological variables like blood pressure, temperature and the amount of salt levels in the blood. These sensors send signals to the brain, the brain is known as the control centre, as a variable diverges from normal conditions. This can also alert changes to compensate for the diverge in order to restore the variable again back to its normal. An example of this is when the human body controls its temperature of 98.6 degrees Fahrenheit. This occurs when the body shivers; this produces heat for when the outside conditions are low and …show more content…
An example of this in the human body is blood clotting. In the event of when there is a cut on the skin, the blood vessels break, because of this the platelets in the blood begin to gather at the location of the cut. The platelets start to discharge various different chemicals, this alerts more platelets and therefore more signals that are chemical are given out. The platelets and proteins combine together to aid the clotting of the cut on the surface of the skin. The process that causes such bleeding to terminate is called hemostasis. Hemostasis occurs in several ways. Another word that is also used for clotting of the blood is known as coagulation. Many specialised molecules and cells are vital in the process of clotting such as platelets, vitamin K, proteins and
