what is medulla oblongata

Your friends have answered correctly- 

Medulla Oblongata is the structure found in the human brain. The major function of Medulla Oblongata is to control autonomic functions (that are not in human control) like breathing, respiration, heart Beat. It is also involved in body secretion, reflexes, swallowing, coughing and sneezing actions. Since Medulla Oblongata performs various functions critical to the body, damage to this structure can be fatal.
