week discussion 2

Discussion week 2 Name: Institution: Date: The automatic nervous system (ANS) is responsible for maintaining homeostasis in the body through automatic reflexes (Raff, 2003). Human beings typically maintain a core body temperature with balancing occurring because of heat loss or gain. In the process of running, the body generates heat even in cold weather raising the core body temperature. At the initial stages of running, the heat is necessary, but as running continues there is excess heat generated in the body. Sweating is one of the ways through which to cool the body by way of evaporation and cooling of the skin, also characterized with increased blood flow. After running, the thermoreceptors also send signals to the nervous system, leading to vasodilation which lowers the Basal metabolic rate causing heat loss. Ultimately, the thermoreceptors in the skin and hypothalamus maintain the core body temperature. Exposure to Malathion inactivates acetylcholinesterase ...
