D
Thyroid gland
Verified step by step guidance1
Begin by understanding the basic anatomy of the endocrine system, which consists of glands that secrete hormones directly into the bloodstream.
Identify the thyroid gland, which is located in the neck, just below the Adam's apple, and is responsible for producing hormones that regulate metabolism.
Recognize the unique shape of the thyroid gland, which is often described as a butterfly shape due to its two lobes connected by a narrow isthmus.
Compare the thyroid gland's shape with other glands in the endocrine system, such as the adrenal gland, pineal gland, and pituitary gland, none of which have a butterfly shape.
Conclude that the thyroid gland is the correct answer based on its distinct butterfly shape, which is a key identifying feature.
