Step 1: Concept
Vital involuntary functions are controlled by the brainstem to ensure survival without conscious effort.
Step 2: Meaning
The respiratory center is a group of neurons that controls the rate and depth of breathing.
Step 3: Analysis
The Cerebrum handles higher functions; the Cerebellum handles balance. The Medulla oblongata (part of the brainstem) contains the primary centers for regulating heart rate and respiration.
Step 4: Conclusion
The medulla oblongata is the anatomical location for the primary respiratory control center.
