What does the Automatic Nervous System (ANS) regulate?

Action of smooth muscles, glands, blood vessels, heart, and breathing
Consciousness and mental activities
Movement of voluntary muscles
Sensing of pain and pressure

The correct answer is: Action of smooth muscles, glands, blood vessels, heart, and breathing

The Automatic Nervous System (ANS) is responsible for regulating various involuntary processes such as the action of smooth muscles, glands, blood vessels, heart rate, and breathing. These functions are controlled by the sympathetic and parasympathetic branches of the ANS. Option B, consciousness and mental activities, are regulated by the Central Nervous System (CNS). Option C, movement of voluntary muscles, is controlled by the Somatic Nervous System. Option D, sensing of pain and pressure, is regulated by sensory nerves in both the ANS and CNS. Therefore, A is the most accurate and comprehensive answer.
