During surgical intervention, an organ is removed from a 34-year-old patient and sent for histologic evaluation. The pathologist examines the slide. The organ is encased in a connective tissue capsule that extends septae into the organ's substance, which is portioned into cortex and medulla. It is richly vascularized and capsular blood vessels penetrate along with the septae. The medulla is fairly homogenous and consists of chromaffin cells, but in the cortex, three concentric zones can be distinguished. Which of the following is the most likely organ?
