Final answer:
Involuntary actions are associated with the Autonomic nervous system (ANS), which regulates vital functions for maintaining homeostasis and operates independently from our conscious control.
Step-by-step explanation:
Involuntary actions in the human body are typically associated with the Autonomic nervous system (ANS). This system is responsible for the involuntary control of the body, primarily managing essential functions for maintaining homeostasis, such as the regulation of the heart rate, digestion, respiratory rate, pupillary response, and more. The ANS operates automatically and comprises two parts, the sympathetic and the parasympathetic nervous systems, which work together to maintain balance within the body. In contrast, the somatic nervous system (SNS) is responsible for voluntary movements of skeletal muscles.
