D) Growth stimulation
Ans: B
The endocrine system consists of various glands, tissues, or clusters of cells that produce and release hormones. Hormones are chemical messengers that stimulate and/or regulate the actions of other tissues, organs, or endocrine glands that have specific receptors to a hormone. Along with the nervous system, the endocrine milieu influences all physiologic effects such as growth and development, metabolic processes related to fluid and electrolyte balance and energy production, sexual maturation and reproduction, and the body's response to stress. The release patterns of the hormones vary, but the level in the body is maintained within specified limits to preserve health.
