Question

Which of the following is an example of homeostasis?

A) The pituitary gland releasing high levels of LH in response to estrogen

B) The ANS activation in response to smelling food

C) Increased ADH release in response to increased blood osmolarity

D) Pupil dilation in response to SYN pathway activation

Answer 1

Answer

Example of homeostasis is : Increased ADH release in response to increased blood osmolarity

• Homeostasis is the physiologic change in the body in order to maintain balance between internal and external envornment.
• Homeostasis is mainly acheived through negative feedback mechanism.
• Increased blood osmolarity is detected by osmoreceptors in hypothalamus.
• It triggers posterior pituitary to release ADH.
• ADH increase water reabsorption to decrease blood osmalarity.
