Endocrine glands typically:

Correct answer: A. Are ductless

  • A. Are ductless
  • B. Release enzymes
  • C. Release neurotransmitters
  • D. Release their contents out of the body

Explanation

Endocrine glands are ductless because they secrete hormones directly into the bloodstream. These hormones travel throughout the body to target organs and tissues, regulating various physiological processes. Lack of ducts allows hormones to quickly reach their destinations, ensuring rapid and efficient communication within the body's endocrine system. This direct secretion into the bloodstream enables precise control and coordination of bodily functions.

About Coordination and Control

Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
