1) blood clotting
2) release of oxytocin during child birth
3) protein digestion- presence of partially digested protein triggers the secretion of HCl and pepsin
4) In nerves, a threshold electric potential triggers the generation of much larger action potential

∙ 10y agoWell first lets define a feedback mechanism. It is defined as a system having influence over another system either positively or negatively. Positive can be done in the form of rewards, these always seem to work for people.

Feedforward feedback control?
Feedforward is a preparatory control. EX. Smelling food leads to salivation and production of stomach acid in preparation of food. OR Starting to exercise increases heart rate and breathing rate in preparation of running low on oxygen for muscles. Feedback is a control mechanism where the product of the end mechanism either enhances or inhibits the start of the mechanism Positive feedback enhances Negative feedback inhibits
What is the endocrine definition of self-regulating?
The endocrine system has four major mechanisms of control that regulate its functions. They are: Hormonal control, neural control, negative feedback, and positive feedback.
What is a control mechanism that responds to a stimulus by decreasing its intensity called?
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.
Which process illustrates a feedback mechanism in plants?
A process that illustrates a feedback mechanism in plants is when the guard cells change the size of a leaf's openings to control gas exchange. Guard cells are located in the epidermis of leaves.
What feedback control reduces variations away from a desired physiological state?
Negative feedback since the positive one increases the change and it is used to speed up processes.
Is Oxytocin release a positive or negative feedback control mechanism?
positive
Is it true oxytocin release is an example of a positive feedback control mechanism?
Yes
Is oxytocin an adenohypophyseal secretion?
no, it's release is the effect of a positive control feedback mechanism
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor

Do positive feedback makes homeostasis get out of control?
yes...
Why is a cycle of events in one step control or affect a previous step?
feedback mechanism
What is a control mechanism that controls an earlier reaction?
positive ffedback
Why is positive feedback helpful in blood clotting but unsuitable for the regulation of body temperature?
Positive feedback accelerates the clotting process, but temperature would rise out of control.
What is the endocrine definition of self-regulating?
The endocrine system has four major mechanisms of control that regulate its functions. They are: Hormonal control, neural control, negative feedback, and positive feedback.
What is the negative -feedback mechanism?
The body has several negative feed back mechanisms. In negative feedback loops our body will seek to reverse th direction of a stimulus. Meaning our body dislikes the stimulus, it will attempt to reverse it. Some examples: blood pressure, temerature control, blood glucose levels.
