It is the somatic nervous system that transmits information to voluntary muscles and the autonomic nervous system transmits information to involuntary muscles.
Somatic nervous system transmits information to voluntary muscles
Autonomic nervous system transmits information to involuntary muscles
Explanation:
Somatic nervous system or voluntary nervous system controls the skeletal muscles thus controlling the voluntary body movements. It is made of sensory nerves and motor nerves. Sensory nerves transmit the signal from the body receptor to central nervous system (CNS). Motor nerves carry the commands from CNS to the body.
Autonomic nervous system controls cardiac muscles, smooth muscles and glandular tissue thus controlling the involuntary body functions like digestion, respiratory rate, heart rate etc. It is further classified into sympathetic and parasympathetic nervous system. Sympathetic system is activated during threat and is responsible for fight or flight response. Parasympathetic system brings back the body to calm state and is responsible for rest and digest response.
During digestion - our food that is eaten gets further broken down into simpler nutrients and compounds. Absorption is required for these nutrients to be properly absorbed by our digestive system. Metabolism is responsible for the speed of this process. This ws it in a nutshell :)
