1. Based on the first situation, how does the feedback mechanism regulate homeostasis in body temperature?
Regulating the body temperature to a set point of normal range (37°C or 98.6°F) is an example of negative feedback mechanism. Negative feedback is a type of action or response that controls, decrease, and maintains the concentration of any variables to an optimum amount within the normal range.
For the regulation of body temperature, the negative feedback helps the body to achieve the homeostasis when the nervous system responds to the stimulus and signals the dermal blood vessels to dilate and triggers the sweat gland to produce sweat. The sweating response leads to decrease the body's thermostat and this is where the body achieve the homeostasis.
2. In the second situation, does positive feedback result to homeostasis? Why or why not?
Positive feedback mechanism indicates an increase of production of certain variable. This is also a type of response that surpasses the amount of a set point in order to re-achieve the homeostasis.
To answer your question, does positive feedback result to homeostasis?
Definitely yes. During labor, the contractions force the head of the infant towards the cervix. The contraction is a type of stimulus and when it's detected by the receptors, it signals the nervous system to release more oxytocin. The production of oxytocin is a positive feedback, because itsecretesoxytoxinbeyondthenormalamount.Oxytocinis essential during labor becauseitincreases the uterine contractions. When the uterine contracts and the cervical walls dilate to its maximum (10cm) the infant will be delivered successfully. The positive feedback ends when the baby is delivered and this is where the homeostasis were maintained.
