Verified step by step guidance

Understand the concept of germ layers: During embryonic development, three primary germ layers form, known as the ectoderm, mesoderm, and endoderm. Each layer gives rise to specific organs and tissues.

Identify the mesoderm layer: The mesoderm is the middle layer of the three germ layers. It is responsible for forming structures such as muscles, bones, the circulatory system, and certain internal organs.

Recognize organs derived from the mesoderm: The heart is a key organ derived from the mesoderm. Other structures include blood vessels, skeletal muscles, and the kidneys.

Differentiate between the germ layers: The ectoderm forms the nervous system and skin, while the endoderm forms the gastrointestinal tract and associated organs like the liver and lungs.

Apply this knowledge to the problem: Given the options, identify which organ is derived from the mesoderm. The heart is the correct answer, as it develops from the mesoderm layer.
