Which of the following statements about homeostasis are false?

A It is defined as a stable state of the normal body.

B The central nervous system, heart, lungs, kidneys and spleen are the essential organs that maintain homeostasis at a normal level.

C Elective surgery should cause little disturbance to homeostasis.

D Emergency surgery should cause little disturbance to homeostasis.

D The normal physiological state of the human body is referred to as homeostasis – a normal internal (the milieu intérieur of Claude Bernard). All the vital organs – the brain, heart, lungs, kidneys and, to a lesser extent, the spleen – play an important role in its maintenance. These organs are interdependent and thus help to maintain a normal fluid and acid–base balance.In the elective situation, the patient is always optimised prior to any operation, thereby minimising the homeostatic disturbance. The extent of surgery also plays a part. Disturbance in the homeostasis to some degree occurs in emergency surgery; this depends upon the extent of injury, presence of sepsis and any ongoing insults. If the patient has co-morbid conditions, postoperatively the return to normal homeostasis would take longer than in those with no co-morbidity. In such cases, care in a high-dependency or intensive care unit (ICU) is essential.

Return to normal homeostasis after an operation would depend upon the presence of co-morbid conditions
