Verified step by step guidance

Step 1: Understand the concept of endocrine function. Endocrine organs release hormones directly into the bloodstream to regulate various physiological processes. Examples include the thyroid gland, pancreas, and adrenal glands.

Step 2: Review the functions of each organ listed in the question. The thyroid gland is a well-known endocrine organ that produces hormones like thyroxine (T4) and triiodothyronine (T3). The pancreas has both endocrine and exocrine functions, with its endocrine role involving the secretion of insulin and glucagon.

Step 3: Examine the liver's role. While the liver is not primarily an endocrine organ, it does have some endocrine-like functions, such as producing angiotensinogen and insulin-like growth factor 1 (IGF-1). Therefore, it has partial endocrine activity.

Step 4: Investigate the spleen's function. The spleen is primarily involved in filtering blood, recycling red blood cells, and supporting immune functions. It does not produce hormones or have an endocrine role.

Step 5: Conclude that the spleen is the organ in the list that does NOT have an endocrine function, as its primary role is related to blood filtration and immune support rather than hormone secretion.
