Questions: QUESTION 11 Which system(s) form the communication or "feedback" loops to maintain homeostasis? endocrine system nervous system both a b neither a nor b

The answer is the third one: both a & b.

Explanation:

• Endocrine System: This system uses hormones to send signals throughout the body. It plays a crucial role in maintaining homeostasis by regulating processes such as metabolism, growth, and reproduction. Hormones act as messengers that can trigger responses in target organs, helping to maintain balance in the body's internal environment.

• Nervous System: This system uses electrical signals to communicate rapidly between different parts of the body. It is essential for maintaining homeostasis by controlling and coordinating bodily functions, such as temperature regulation, heart rate, and respiratory rate. The nervous system can quickly respond to changes in the environment and adjust bodily functions accordingly.

• Both a & b: Both the endocrine and nervous systems work together to form communication or "feedback" loops that are essential for maintaining homeostasis. They often interact and influence each other to ensure the body's internal environment remains stable.

• Neither a nor b: This option is incorrect because both the endocrine and nervous systems are integral to maintaining homeostasis through feedback mechanisms.

In summary, both the endocrine and nervous systems are involved in forming communication or "feedback" loops to maintain homeostasis.
