Verified step by step guidance

Begin by identifying the primary function of each organ listed in the options. The pancreas is primarily involved in digestion and blood sugar regulation, the pituitary gland is a major endocrine organ, the thymus is involved in immune function, and the kidneys are primarily excretory organs.

Understand that the question asks for an organ that is not primarily an endocrine organ but still produces hormones. This means the organ's main function is something other than hormone production.

Consider the kidneys: their main function is to filter blood and produce urine, which is an excretory function. However, they also produce hormones such as erythropoietin, which stimulates red blood cell production, and renin, which helps regulate blood pressure.

Compare the kidneys to the other options. The pancreas has a significant endocrine role in producing insulin and glucagon, the pituitary gland is a central endocrine organ, and the thymus is primarily involved in immune system development.

Conclude that the kidneys fit the criteria of the question as they are primarily excretory organs but also produce hormones, unlike the other options which have more direct endocrine functions.
