- Which component of a homeostatic control mechanism would the life function "responsiveness" be best associated with? O effector O gland O receptor O muscle none of the above Next ► « PreviousWrite a long response that thoroughly explores examples of structure and function working together at the following levels in the interest of maintaining homeostasis: A – Organ B – Organ System C – Organism Be specific at each level of organization while keeping the greater good of the whole body in mind. If there was significant dysfunction at the organ level, predict how the effects of that flaw might ripple though higher levels of organization mentioned above? How might this affect the overall health of the person?Identify THREE (3) of the body's physiological responses to execise and explain how each helps maintain homeostasis

What happens when homeostasis fails? List the three basic components of a control system and give an example. Describe the components of a reflex pathway. Contrast the response loop and the feedback loop. Explain the relationship between a regulated physiological variable and its setpoint. Is the physiological variable exactly at its setpoint? Compare and contrast negative and positive feedback. Give a biological example of each. Is the setpoint constant or can it change over time? If setpoints can change over time, what is this called? Chapter 2:Organismal homeostasis depends upon the presence of control systems. Give a physiological example of a negative feedback control system its positive feedback. Clearly describe the role(s) that each of the following elements plays in all control systems: such as controller, effector and receptor.
- 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. Justify your…In discussions of feedback in biological systems, negativefeedback is typically emphasized, and positive feedback is oftentreated as an anomaly. In fact, positive feedback is common inreproductive physiology. List two or three examples of positivefeedback. Explain how positive feedback functions to advantagein each case. If possible, discuss whether homeostasis is alwaysideal.Which of the following shows body homeostasis? I. The excretion of urine due to excess fluid in the body. II. The release of sweat in response to an increase in environmental temperature. II. The release of alkaline seminal fluid before sperm cells pass through the urethra. IV.
