Answer:
The inferior region of the brain stem, the medulla oblongota houses many vital autonomic centers involved in the control of heart rate, respiratory rhythm, and blood pressure.
Step-by-step explanation:
The medulla oblongata is the part of the brain that joins the spinal cord and forms the lower part of the brain stem. In the bulb there are ascending (sensory) and descending (motor) fascicles that communicate the spinal cord with the brain, in addition to numerous nuclei or centers (masses of gray matter) that regulate various vital functions. The medulla oblongata has the function of controlling vital and unconscious elements such as the heartbeat and blood pressure. Thus, it is responsible for maintaining the heart rate and regulating vasoconstriction. Also, it manages the control of respiratory function, maintaining it at all times.
