The functions of the nervous system include:
1. A. Releases hormones - This statement is not accurate. The endocrine system is responsible for releasing hormones, not the nervous system. Hormones are chemical messengers produced by endocrine glands like the pituitary gland and adrenal gland.
2. B. Produces white blood cells - This function is primarily attributed to the immune system, particularly the bone marrow where white blood cells are produced. White blood cells play a crucial role in defending the body against infections.
3. C. Supplies oxygen to cells - The respiratory system is responsible for supplying oxygen to cells by facilitating the exchange of oxygen and carbon dioxide in the lungs through breathing.
4. D. Monitors chemical changes in the blood - This is a function of the nervous system. The nervous system monitors and responds to changes in the internal and external environment of the body through sensory receptors and helps regulate various physiological processes.
