keeping things constant‚ therefore positive feedback cannot be used as a homeostatic mechanism. Homeostasis is used as a survival tool because it enables animals to adapt to the ever changing environment (Tortora 1999). Without this ability death may occur‚ unless medical treatment is executed to bring about the natural occurrence of a feedback system (Clancy 2002). Disease will also result when there is a failure in the homeostatic control system because according to Clancy (2002) homeostasis provides

The cardiovascular system plays a crucial role in pumping blood‚ nutrients‚ and respiratory gases throughout the body. Blood pressure is the force that pushes blood against the blood vessel walls and delivers these essential elements to the body. The highest pressure is when the artery is maximally stretched and is recorded as the systolic pressure. The lowest pressure occurs when the artery recoils and is relaxed is known as the diastolic pressure. Mean arterial pressure is the average blood pressure

seek to answer this unique question. There is the understanding that human body is made of systems that regulate activities as moving‚ sleeping‚ eating and drinking.

D2 You could include examples of what happens when homeostatic mechanisms do not function efficiently and the resulting symptoms. E.g. Irregular heartbeat or inability to control blood sugars. Irregular heartbeat. I will be firstly talking about an irregular heartbeat. An irregular heartbeat is an arrhythmia also called dysrhythmia. Heart rates can also be irregular. A normal heart rate is 50 to 100 beats per minute. Arrhythmias and abnormal heart rates don’t necessarily occur together. Arrhythmias
