Which Body Process Is Controlled Using a Positive Feedback Loop

A feedback system will include a receptor that detects the stimuli a control center that receives the input from the receptor generates an output an effector that receives the output produces a response. The first contractions of labor the stimulus push the baby toward the cervix the lowest part of the uterus.

Positive And Negative Feedback Loops In Biology

Which of the following describes a body process that is controlled using a positive feedback loop.

. When you have a cut on your finger positive feedback contributes to the rapid formation of a platelet plug in an injured blood vessel. Which of the following describes a body process that is controlled using a positive feedback loop. A positive feedback loop keeps the stimulus in the same direction and presumably speeds up the action.

Positive Feedback can be explained by an example. For example during blood clotting a cascade of enzymatic proteins activates each other leading to the formation of a fibrin clot that prevents blood loss. Decreasing body temperature in response to elevated body temperature C.

Which of the following describes a body process that is controlled using a positive feedback loop. The process of wound clotting is a positive feedback loop. As the baby suckles the mothers pituitary gland produces more of the hormone prolactin which causes more milk to be produced.

Increasing strength of uterine contractions in response to cervical stretch 7. A positive feedback mechanism is defined as a feedback mechanism that reinforces the change in the controlled condition A particular stimulus causes an. Increasing body temperature in response to a drop in body temperature B.

The cervix contains stretch-sensitive nerve cells that monitor the degree of stretching the sensors. A increasing body temperature in response to a drop in body temperature B decreasing body temperature in response to elevated body temperature C decreasing blood glucose in response to elevated blood glucose D increasing strength of uterine contractions in response. In response to elevated body temp.

This type of feedback is normal for the body provided there is a definite endpoint. 88 Which of the following describes a body process that is controlled using a positive feedback loop. The increase in contractions causes more oxytocin to be released and the cycle goes on until the baby is born.

Which of the following describes a body process that is controlled using a positive feedback loop. A condition not regulated by a negative feedback loop would be. When the body is damaged inside or outside the damaged tissues release factors that cause platelets to adhere to the tissue the effector at the site of the wound.

A feedback loop is a cycle of events in which the status of the body condition is monitored evaluated changed to maintain homeostasis. A increasing body temperature in response to a drop in body temperature b decreasing body temperature in response to elevated body temperature c decreasing blood glucose in response to elevated blood glucose d increasing strength of uterine contractions in response. During labor a hormone called oxytocin is released that intensifies and speeds up contractions.

In most cases positive feedback is harmful but there are a few instances where positive feedback when used in limited fashion contributes to normal function. In this way a negative feedback loop brings a system closer to a target of stability or homeostasis. A positive feedback loop results in a change in the bodys status rather than a return to homeostasis.

Breastfeeding is also a positive feedback loop. A good example of a positive feedback system is child birth. Increasing strength of uterine contractions in response to cervical stretch.

Positive feedback loop Postive feedback is a control mechanism in which it encourages and intensifies a change in the bodys physiological conditionactually driving it farther out of the normal rangeThis type of feedback is normal in bodyMost comm. This moves the fetus even closer to the cervix which causes more oxytocin to be produced until childbirth occurs and the baby leaves the womb. The birth ends the release of oxytocin and ends the positive feedback mechanism.

An explosion of chemical events that lead to blood clotting also known as coagulation is an example of positive feedback loops seen in the animal body. If blood glucose gets too low the body releases glucagon which causes the release of glucose from some of the bodys cells. Which of the following describes a body process that is controlled using a positive feedback loop.

The composition of this body fluid which fills the narrow spaces between cells and tissues directly affects the proper functioning of cells. A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. Feedback loop is defined as a system used to control the level of a variable in which there is an identifiable receptor sensor control center integrator or comparator effectors and methods of communication.

This happens when a product or event occurs that changes the bodys reaction. In a positive feedback mechanism the output of the system stimulates the system in such a way as to further increase the output. Mammography and bone densitometry are goof examples of which of the following types of medical imaging.

Decreasing blood glucose in response to elevated blood glucose. Decreasing bloodglucose in response. Answer to Solved Describe a body process that is controlled by.

The process of blood coagulation hemostasis is a cascading positive feedback loop. The injured area attracts platelets and each of these platelets. The maintenance of homeostasis in the body typically occurs through the use of feedback loops that control the bodys internal conditions.

In response to a drop in body temp. Which of the following describes a body process that is controlled using a positive feedback loop.
