Task 4
P5- Explain the concept of Homeostasis.
Homeostasis describes how your body regulates its process to keep its internal conditions as stable as possible. Human cells are efficient but very demanding so the homeostasis is needed. Temperature and blood PH change slightly while others such as blood glucose very considerably throughout a normal day without producing any harmful effects. Homeostasis is the maintenance of a constant internal environment in the response to a change in the external environment. An example of homeostasis could be that an individual may feel hot from doing exercise or a workout, our bodies maintain homeostasis by sweating, this helps us to cool down and maintain the body temperature. A negative feedback in the body is where a change the level of one natural leads directly to a drop or increase. Negative feedback is the mechanism in which our body sustains conditions within specific perimeters. The body does this by conflicting an alteration that deviates from the norm.
Negative feedback- This makes sure that when the levels return to normal, the corrective mechanisms are scaled down. This happens when your body maintains conditions within particular limits. The body will do this by opposing a change that deviates from the normal, Core temperature falls.
Core temperature rises- The drop detected by hypothalamus: The brain send out signals to your body that brings out shivering and vasoconstriction. Temperature turns to normal which is 36.9c. Rise detected by hypothalamus, the brain sends out signals to your body that brings out sweating and vasodilatation.
An example of the negative feedback is if it’s cold outside, the internal temperature of the house will drop, because cold air will seep in through the walls. When the temperature drops below the point at which the thermostat is set, the thermostat turns on the heater. As the temperature within the house rises, the thermostat notices this change and
