Homeostasis – The ability of an organism or cell to maintain the same internal environment regardless of changes in the external environment. 2. Metabolism –The chemical reaction that occur in a cell. 3. Experiment –Procedures used to test a hypothesis. 4. Control group – Subject(s) that goes through the

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

BTEC BIOLOGY ASSIGNMENT 3 TASK 1 HOMEOSTASIS Homeostasis can be defined as a point of balance or internal equilibrium that all kind of system both living and non-living can work to keep themselves in this state of balance. Mechanisms of homeostasis in human body Temperature Regulation: If your body too hot or cold‚ there are several ways in which your temperature can be controlled. They involve sweating‚ shivering‚ capillaries and hairs. As we learn in the class when your body becomes; Too

1: HOMEOSTASIS: A FRAMEWORK FOR HUMAN PHYSIOLOGY An understanding of homeostasis is essential to the successful mastery of physiology. It is one of the unifying concepts of physiology. Even though our review of various systems of the body are presented across differetn weeks‚ they are all inextricably linked by their role in maintaining the constant internal environment of the body. Learning objectives: The Scope of Human Physiology Students should be able to: identify physiology as the

Homeostasis helps in maintaining a balance in proteins found in cells‚ to ensure optimal function. If homeostasis fails to maintain this balance‚ the “normal” aging process and disease contract or cure are affected at a greater impact In the case that homeostasis fails‚ systems in the body will fail to act efficiently because the body would
