the respiratory system
The autonomic nervous system is a division of the peripheral nervous system that controls automatic responses in the body, such as the heart rate, hormone levels, gastrointestinal functions, and metabolism.
The brain is part of the nervous system and not the breathing (respiratory)system.
The hypothalamus is a part of the central nervous system.
Central nervous system. In fact, the brain is the CENTER of the central nervous system.
The Brain, specifically the brain stem and the central nervous system that controls any "unconscious" activities like breathing and pulse rate.
The autonomic nervous system is responsible for regulating heart rate and breathing. Specifically, the sympathetic division of the autonomic nervous system controls functions like increasing heart rate and dilating airways, while the parasympathetic division controls functions like slowing heart rate and constricting airways. Trembling can be a result of activation of the sympathetic nervous system in response to stress or fear.
The central nervous system.
The central nervous system is part of the nervous system, but it is only the brain and the spinal cord.
Primarily breathing is controlled by the diaphragm but the intercostals betwen the ribs are also invilved especially during forced respiration.
