Q:

How does the nervous system maintain homeostasis?

A:

Quick Answer

The nervous system maintains homeostasis by sending electrochemical signals throughout the body, coordinating and executing both the voluntary and involuntary processes that maintain homeostasis, according to Penn Medicine. The nervous system is comprised of fibrous axons, which stretch throughout the body and interconnect to coordinate activity, states Wikipedia.

Full Answer

The brain is the ultimate control center of all activity in the body and is the organ that is primarily responsible for the maintenance of homeostasis, notes the University of California at Berkeley. The hypothalamus is of particular importance in homeostasis. It controls the pituitary gland, thus regulating the endocrine system, and also exerts great influence over internal organs via the nervous system.

The autonomic nervous system plays a particularly vital role in the maintenance of homeostasis, notes the National Center for Biotechnology Information. The autonomic nervous system regulates involuntary bodily functions, according to Wikipedia.

The nervous system is the most complex system in the body and is comprised of the central nervous system and the peripheral nervous system, states Penn Medicine. The central nervous system is comprised of the brain and the spinal cord, whereas the peripheral nervous system is composed of the nerve extensions beyond those central pathways. Both, when combined, interconnect all of the parts of the body and allow for the processes creating homeostasis to occur.

  • Q:

    How does the endocrine system help maintain homeostasis?

    A:

    The endocrine system creates and releases hormones that transport to various parts of the body to control the body's reactions to things like stress, pain, growth and nutrient intake. These hormones can be thought of as messengers that give directions to different parts of the body, allowing the body to react to changes and maintain homeostasis.

  • Q:

    How does excretion contribute to homeostasis?

    A:

    Excretion contributes to homeostasis by getting rid of urea, carbon dioxide, excess salts and excess water to maintain a stable body condition. These compounds are filtered from the blood by the kidneys, which then combine them to form urine. The urine is then passed by ureters to the bladder and is eventually excreted from the body through the urethra.

    How does the immune system maintain homeostasis?

    A:

    The immune system maintains homeostasis by preventing pathogens from disrupting the body's normal functioning. It achieves this in various ways, including adaptive immunity when the body encounters a new pathogen, innate immunity, secreting acids onto the skin and using mucus membranes to breakdown bacteria.

  • Q:

    Where is nervous tissue found?

    A:

    Nervous tissue is found in peripheral nerves throughout the body and in the organs of the central nervous system, the brain and spinal cord. Nerve tissue is composed of neurons, which are specialized cells able to react to stimuli by sending a signal down a long strand of cell known as an axon. Nervous tissue is responsible for receiving information from the senses, processing it and sending out instructions.
