In human physiology, what is the primary function of the endocrine system?
A
To exchange oxygen and carbon dioxide between the air and the blood in the lungs
B
To produce rapid electrical signals that travel along neurons to coordinate immediate responses
C
To regulate body processes by secreting hormones into the bloodstream to act on target cells and organs
D
To provide structural support and mineral storage by forming the skeleton
Verified step by step guidance1
Step 1: Understand the role of the endocrine system in the human body. The endocrine system is composed of glands that secrete hormones directly into the bloodstream.
Step 2: Recognize that hormones are chemical messengers that travel through the blood to target cells or organs, influencing various physiological processes.
Step 3: Differentiate the endocrine system from other systems mentioned: the respiratory system exchanges gases, the nervous system transmits electrical signals, and the skeletal system provides support and mineral storage.
Step 4: Identify that the primary function of the endocrine system is to regulate body processes such as growth, metabolism, reproduction, and homeostasis by hormone secretion.
Step 5: Conclude that the correct description of the endocrine system's primary function is its role in regulating body processes through hormone secretion acting on target cells and organs.
