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.

A 75-year-old man was found unconscious in his bathroom after fallingand hitting his head. He survived for several hours but died later in thehospital. An autopsy was performed to determine the exact cause ofdeath. Evidence indicated that the man had suffered two strokes, bothdue to blocked blood vessels. One had occurred a few weeks earlier;the other had occurred very recently and may have led to the fall.Autopsy findings also indicated that, when the man hit his head, somedamage to his brain occurred as well. Based on what you know aboutinflammation and the cellular structure of the brain, describe what thepathologist found in each of the damaged areas of the brain.
