Verified step by step guidance

Understand the three primary germ layers in human development: ectoderm, mesoderm, and endoderm. Each layer gives rise to specific tissues and organs.

Identify the mesoderm, which is the middle layer formed during the early stages of embryonic development. It is responsible for developing structures such as muscles, bones, and the circulatory system.

Recognize that the heart is part of the circulatory system, which develops from the mesoderm. This layer also contributes to the formation of the skeletal system, muscular system, and connective tissues.

Differentiate the other options: the lungs develop from the endoderm, the brain from the ectoderm, and the liver from the endoderm.

Conclude that the heart is the correct answer as it develops from the mesoderm, aligning with the functions and structures associated with this germ layer.
