How does the nervous system the muscular system control heart rate, digestion, and respiration

MUSCULAR SYSTEM :
1. Receptors in muscles provide the brain with information about body position and movement.
2. The brain controls the contraction of skeletal muscle.
3. The nervous system regulates the speed at which food moves through the digestive tract.

HEART RATE :
1. The brain regulates heart rate and blood pressure.

DIGESTION :
1. Digestive processes provide the building blocks for some neurotransmitters.
2. The autonomic nervous system controls the tone of the digestive tract.

RESPIRATION :
1. The brain monitors respiratory volume and blood gas levels.
2. The brain regulates respiratory rate.
