- 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.

- dave, a year one nursingstudent attended a fresher’s welcome party organized by the CIU School of Nursing and Midwifery. There was plenty of food and drinks at the party and dave found himself taking two full plates of food containing chicken, fatty meat, rice, potatoes and greens. Hiscolleague told him that he had taken excess of what the body required. Mbwatekamwawondered how hisbody would respond. How does the body respond to excess carbohydrates? What happens to the excess fats in the body?1) As a physiologist, which of the following terms should you immediately associate with negative feedback regulation?

- 16. Identify each event found below as a homeostatic response or not a homeostaticresponse. Remember to give the rational for each response. a) A marathon runner is sweating as she completes 10 km of a 20 km race b) Children at a party enjoy eating the chocolate cookies and finish everything on theplate.Figure 16.2 When bacteria are destroyed by leukocytes, pyrogens are released into the blood. Pyrogens reset the body’s thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise?For the following scenarios, state which part of the brain would be affected and give reasons for your choice of answer in each case. a) When the immune system of a person with Tuberculosis is trying to fight off the bacteria, chemicals are produced from particular lymphocytes. These chemicals raise the core body temperature and the core body temperature ‘thermostat’ setting is also changed. State which part of the brain would be affected and explain your answer. b) During exercise the heart rate increases. After exercise, there is a recovery period where the heart rate is returned to normal. State which part of the brain would be damaged if this could not occur and explain your answer.
- One of our homework questions in Anatomy 1 states Describe the relationship between homeostatic imbalance and disease. I understand that homeostasis is what our bodies use to keep balance and regulation. Is this question something along the lines of; When our bodies catch a flu/virus the body fights off the disease by giving us a fever. The fever fights off the infection by chemical responses that come from the receptor detecting change in the body and trying to get all levels of each system back to it's regular functioning levels? Thank you, Julianne1. Draw block diagrams to represent the following feedback control systems: a) Control of human skin temperature by sweating b) Control of a diabetic person's blood sugar level through insulin injections Note: Besides the standard feedback control system components, include disturbances in the diagram. Label each block and signal with their physical names. Briefly explain how each system works.Earnest, a 50-year-old man, has been very tired and irritable lately, and visits his healthcare provider with his wife because he is worried about faint tingling sensations. Further questioning reveals that he is a very heavy drinker; his wife mentions severe memory lapses where he makes up stories about his life that didn’t really happen. You also notice an oddness in his gait. Lab reports return negative for megaloblastic anemia. Which of the following is likely responsible for Earnest’s symptoms? Question 13 options: a) Malabsorption of iron due to excess alcohol intake b) Neurologic damage due to B12 deficiency c) Wernicke –Korsakoff syndrome (thiamine deficiency) d) General fat-soluble vitamin deficiency due to alcohol induced pancreatitis
