Group of answer choices move to a warmer location or put on a sweater skeletal muscles contract sweat glands initiate sweating skin blood vessels dilateImagine you are the healthcare administrator of a 180-bed facility. Susan is a kitchen assistant who works in your healthcare facility. Susan was recently in contact with a family member who has influenza, then came to work with severe sniffles and sneezes. She also felt hot, and then cold, and had a few body aches. Susan believes she cannot afford to stay home, so she went to work and did not tell anyone how she was feeling. Susan assisted in the preparation of three meals before the chef noticed her physical condition and sent her home. What contributing factors put your patients and other staff members at risk? What food preparation practices that Susan was involved in put the patients and other staff members at risk? Which of the top four contributing factors has Susan committed by coming to work as a kitchen assistant in your healthcare facility?
- 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.The tendency of the body to maintain stable internal conditions is called____ .Figure 33.23 When bacteria are destroyed by leuckocytes, 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?
- Other than changes in the blood vessels, state one (1) mechanism in which body temperature can be reduced or increased. Many factors can affect one’s body temperature, such as spending time in hot or cold weather Give two (2) factors that can raise or lower the body temperature.Read the situation below and draw a diagram or illustration on how a fever happens. When bacteria are destroyed by leuckocytes, 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? The hypothalamus maintains the set point for body temperature through reflexes that cause vasodilation and sweating when the body is too warm, or vasoconstriction and shivering when the body is too cold. It responds to chemicals from the body. When a bacterium is destroyed by phagocytic leukocytes, chemicals called endogenous pyrogens are released into the blood. These pyrogens circulate to the hypothalamus and reset the thermostat. This allows the body’s temperature to increase in what is commonly called a fever. An increase in body temperature causes iron to be conserved, which reduces a nutrient needed by bacteria. An increase in body heat also increases the activity of the animal’s…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.

- Outline the events that shows the negative feedback loop that happens when you (choose only one): get a wound, consume too much sugar, get hot by being in a humid place, feel cold, drink too much water, touch a hot surface, get pinched or pricked, or are in a poorly lit room. You are encouraged to do research on the mechanisms that enables the responses for these.The feedback loop shown below is an example of negative feedback that uses the narrowing and widening of blood vessels in the skin to regulate body temperature. DIRECTIONS: Label the diagram using the words or phrases from the word bank. Then answer the questions that follow. body temperature falls body temperature rises normal body temperature vasoconstriction vasodilation Feedback: Feedback: Response: ACY MENT CHA RICH OF EATIO Response: EX Stimulus: Increase in Body Temperature Stimulus: Decrease in Body TemperatureCarlotta, a 29-year-old new mother, was relating to her pediatrician, Dr. O’Farrell, about how exhausting the demands of caring for a new baby can be: “I’m hot and bothered and irritable about small things.” Dr. O’Farrell countered, “Some irritability is to be expected – especially if you’re not getting much sleep.” “She’s always complaining about how warm the house is, and she’s lost weight”, her husband Robert exclaims. After hearing of Carlotta’s concerns, Dr. O’Farrell did a quick exam of her neck, heart rate (92/min resting), and body temperature (99.9˚F) and noticed that her thyroid gland was enlarged. He also noticed that her eyes looked outwardly bulged. “I’m sending you to the endocrinologist, Dr. Mazer, to get checked out and get some blood work.” The results of the lab work are: Thyroxine (T4): 19.5 ug/dL Thyroid stimulating hormone (TSH): 0.1 mlU/L Iodine Levels: 20 ug/dL 1. Which part of the hypothalamic-pituitary-thyroid pathway is malfunctioning? Explain your reasoning.
