Perspiration, known more commonly as sweating, is an autonomic bodily response that decreases body temperature. During perspiration, the skin will secrete sweat that will ther- moregulate body tissues in certain conditions. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. In addition, the blood vessels will increase in diameter via a process called vasodilation, which will bring them closer to the skin and allow heat to more easily dissipate from the body. 3 increased blood temperature identified by central receptors vasodilation of peripheral vessels and skin arterioles to transfer more heat to the skin surface 5 A diagram of thermoregulation in the human body. 2 hypothalamus receives input and activates SNS response heat leaves the body and blood temperature lowers Respond to each part in 2 to 3 complete sentences. activation of sweat glands to begin sweating (a) Identify the type of feedback loop presented in the diagram.

Imagine you are sick and you have fever. Sensors on the skin and brain detect this and communicate with the temperature regulatory center in the brain which then sends out a command to the sweat glands of your body as a result of which you start sweating and in about 15 mins your body temperature comes back to normal for the time being. This this feedback loop, identify the following: sensors control center effector stimulus response
*our body is tightly regulated to maintain an internal (core) temperature of 98.6 degrees F. Your body does not function properly if you get too hot or too cold, partially because protein enzymes get too "stiff" (cold temperatures) or denatured (hot temperatures). If blood temperature rises too high, this is sensed by specialized neurons in the brain. They signal other herve centers, which in turn send signals toʻthe blood vessels of the skin. As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body. If this is not enough to cool the body back to its set point, the brain activates sweating. Evaporation of sweat from the skin has a strong cooling effect, as we feel when we are sweaty and stand in front of a fan. In this example, the brain is a(n): а. гесеptor b. control center nent C. effector eweet alands, are a(n):
