Question

The feedback control mechanism is related with?
a. Bile secretion
b. HCL secretion
c. Hormonal secretion
d. Hering-breuer complex

Answer 1

Hint: Feedback control mechanisms are the roots of the most of the control mechanism. It is a type of a loop in which a product feeds back to control its own production. These control mechanisms are the main part of human physiology and are prominent for the endocrine system. The regulation of hormones and their secretion is only controlled through these mechanisms.

Complete answer:
> Option A:
Bile secretion is a vital secretion done by the liver. It is stimulated by the secretion and secreted into the gall bladder where it is stored under fasting condition. So, the gallbladder is used as a checkpoint to regulate bile secretion. There is no feedback control mechanism in bile. Hence, it is incorrect.

> Option B:
HCL secretion is done by the gastrin hormone. It is initiated by food, the thought, the smell by the G cells. It is based on the varied conditions of gastrin output. So, it is also incorrect.

> Option C:
Hormonal secretion – these are the most prominent mechanism in the endocrine system. Events of positive feedback occur certainly, but negative feedback is more common. These loops of feedback are extensively used for regulation of hormone secretion in the hypothalamus-pituitary complex. Thus, it is the correct choice.

> Option D:
Hering-breuer complex is the reflex action triggered to prevent the over inflation of lungs. So, it is not a type of feedback control method.
Example: Regulation of blood glucose levels in the human body. If glucose levels continue to rise it will lead to diabetes. The body will always respond to the process done and lead a positive or negative control to it.

Hence, the correct answer is option (C).

Note: It is a loop controlling mechanism in the living cells, organisms, ecosystems. It regulates the levels of certain or range of optimal conditions required to the body. It regulates homeostasis. The timing and the amount of secretions from the hormonal gland is controlled by a built -in mechanism of our body called a feedback mechanism. They are generally dependent upon the hormonal secretion levels as feedback occurs when output of a system is routed back as inputs as a part of cause and effect form in a loop chain.
