Difference between Homeostasis and Haemostasis

Ever wondered if those two terms were the same? Discover the difference between Homeostasis and Hemostasis

Homeostasis

In 1878, Claude Bernard presented the idea that the organism is divided into external and internal means. The ability to keep the internal environment in constant balance, working against changes in the external environment, is called Homeostasis .

In humans, body temperature is maintained at approximately 36 ° C, mean arterial pressure is around 100 mmHg and plasma osmotic pressure is around 300 mOsm. Some fluctuations in external factors rarely affect these parameters.

The concept of homeostasis was first used by Walter Cannon in 1926. The term “homeo-” refers to a similar (as opposed to “homo-“, meaning equal) and the term “-stase” refers to condition .

The Nervous and Endocrine systems play an important role in maintaining homeostasis. It is also believed that the immune system plays an important role in maintaining homeostasis. Changes in the external environment that affect an organism are considered stressful as physical or chemical stress, as well as biological, for example by exposure to bacteria.

Hemostasis

Already Hemostasis is a complex series of biological phenomena that occurs in response to injury of a blood vessel in order to stop bleeding.

The hemostatic mechanism includes three processes: primary hemostasis, coagulation (secondary hemostasis) and fibrinolysis. These processes have together the purpose of maintaining the necessary fluidity of the blood, without extravasation by the vessels or obstruction of the flow by the presence of thrombi.

Here, blood vessels, platelets, procoagulant factors and anticoagulant factors are involved. All in balance to stop the bleeding and then dissolve the clot formed.

Conclusion

We can say, then, that hemostasis is part of homeostasis. That is, hemostasis is a mechanism of the organism to maintain the balance of the internal environment.
