Verified step by step guidance

1. Understand the three primary germ layers formed during embryonic development: ectoderm, mesoderm, and endoderm.
2. Recognize that each germ layer gives rise to specific tissues and organs in the body. The ectoderm primarily forms the nervous system and skin, the endoderm forms the lining of the digestive and respiratory systems, and the mesoderm forms muscles, bones, and connective tissues.
3. Identify that connective tissue, which includes bone, cartilage, and blood, originates from the mesoderm layer.
4. Recall that the mesoderm is responsible for forming structures that provide support and movement, which is characteristic of connective tissues.
5. Conclude that connective tissue arises from the mesoderm, as it is the germ layer responsible for developing the supportive and structural components of the body.
