Begin by understanding what a gland is: A gland is an organ in the body that synthesizes substances such as hormones or digestive juices for release into the bloodstream or into cavities inside the body.
Consider the function and size of each gland listed: The adrenal gland is responsible for producing hormones like adrenaline and cortisol, and is relatively small, located on top of the kidneys.
The thyroid gland is located in the neck and produces hormones that regulate metabolism. It is larger than the adrenal gland but still not the largest.
The pancreas is involved in both endocrine and exocrine functions, producing insulin and digestive enzymes. It is larger than both the adrenal and thyroid glands.
The liver, although not traditionally considered a gland, performs glandular functions by producing bile and various proteins. It is the largest internal organ and gland in the human body, surpassing the size of the adrenal gland, thyroid gland, and pancreas.
