- 43. In the process of regulating body temperature, which part of the feedback system includes the sweat producing glands? Group of answer choices control center receptors stimulus effectors7. Thermoregulation is a negative feedback control system in the body. Which of the following statements correctly explains how thermoregulation works? A. In hot temperatures, the body maintains homeostasis by activating the sweat glands to release heat, which cools your skin as it evaporates. B. When the body is hot the blood vessels under your skin get wider. This increases blood flow to your skin where it is cooler C. When the body is cold the blood vessels under your skin become narrower. This decreases blood flow to your skin, retaining heat near the warm inner body. D. All of the above.8. Describe how the body regulate its temperature when shivering and sweating.
- 20. Which of the following is the major cause for inaccuracies in estimations of body composition using bioelectrical impedance analysis? Variations in heart rate Variations in hydration status High levels of body fat Presence of body hair1. Explain the physiologic processes involved in homeostatic regulation of temperature, pulse, respirations, and blood pressure.In some diseases, an infection causes a high fever, resulting in a crisisstate.
