Homeostatic regulation of blood pressure by a negative feedback system the response is fed back into the system‚ and the system continues to lower blood pressure until there is a return to normal blood pressure (homeostasis). A negative feedback system or loop reverses a change in a controlled

INTRODUCTION TO PHYSIOLOGY AND HOMEOSTATIS PHYSIOLOGY 1.1 Intro to Physiology Physiology: the study of the functions of living things‚ how the human body works Two approaches explain the events that occur in body -purpose of the body process - mechanism in which the process occurs Physiologists view the body as a machine whose mechanisms of action can explained in terms of cause and effect sequences of physical and chemical processes. Physiology is closely related to anatomy: the

The Octopus Flask is noted as one of the most popular recorded painting that dates back to 1500-1450 BCE. The art piece is a painting on a ceramic vessel‚ what people referred to as “bottle”‚ it came from the east Cretan site of Palaikastro and is now displayed at the Archeological Museum at Iraklion‚ Crete. The Octopus Flask‚ or the “bottle”‚ is decorated with paintings of marine life in celebration of the Cretan Maritime Power. It consists of an octopus and other marine life “floating” in its

Homeostasis Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes. It is involved in the maintenance of the constant internal environment which includes the function of kidney‚ liver‚ skin‚ etc. In humans‚ homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example‚ we sweat to

referred to as homeostasis (Waugh and Grant 2010). Claude Bernard was a 19th century French physiologist who first discovered the concept of homeostasis. But it was Walter Cannon‚ a 20th century American physiologist who devised the word “homeostasis” (Marieb and Hoehn 2007). Temperature‚ pH‚ blood pressure‚ water and electrolyte concentration and blood glucose levels are the most important physiological variables maintained by homeostatic mechanisms (Waugh and Grant 2010).). Homeostasis is regulated

and external stresses can also affect homeostasis‚ which can also cause hypertension. The organ system it involves is the cardiovascular system. The cardiovascular system is the organ system surrounding the heart‚ blood‚ and blood vessels. One of the most important things that help with homeostasis when dealing with hypertension is the negative feedback system. The system works to maintain a constant balance. If there is an issue in the body’s homeostasis‚ the body reacts with the negative feedback

They involve sweating‚ shivering‚ capillaries and hairs. As we learn in the class when your body becomes; Too
