Model 2 Thermoregulation
8. Based on what I see in Model 2, thermoregulation is the body sensing the temperature and sending out signals to either cool or heat the body.
9. According to Model 2, the Hypothalamus is the portion of the brain that contains sensors that monitor body temperature.
10a. Two mechanisms the body uses to cool itself are when blood vessels in skin dialate to radiate heat and sweat glands increase sweat production.
10b. Two mechanisms the body uses to heat itself are when blood vessels in the skin constrict, and reducing heat loss and muscles begin to shiver, generating heat.
11a. The stimulus in the feedback loop is when the body senses the temperature being too hot and the response to it is using one of the two mechanisms to cool it down. …show more content…
This feedback loop is negative feedback because cooling down the body is when the temperature decreases, and decreasing is negative feedback.
12a. The stimulus in the feedback loop is when the body senses the temperature being too cold and the response to it is using one of the two mechanisms to heat it up.
12b. This feedback is positive because heating up the body is when the temperature is increasing, and increasing is positive feedback.
13a. A positive feedback loop would be helpful in maintaining homeostasis because it keeps the body at a stable state for example if you were to have breathing, you would need and receive positive feedback in order to receive oxygen and not pass out.
13b. A single negative feedback loop would be helpful in maintaining homeostasis because it keeps the body at a stable state for example if you are too hot you would get negative feedback.
14. According to Model 3, the stimulus during childbirth is the baby pushing against the cervix and the response to this is the hypothalamus releasing oxytocin.
15. The hormone that increases the intensity of contractors when released from the hypothalamus is the oxytocin.
16. When the intensity of contractions increases, the stimulus will decrease because it is trying to maintain a normal
