The middle layer is formed during the gastrulation. This layer develops into muscles, bones and blood vessels.

During embryonic development, the process of gastrulation occurs first. This is when the three primary germ layers (ectoderm, mesoderm, endoderm) form, from which all tissues and organs will develop. Following gastrulation, organogenesis begins where specific organs and structures start to form.
Gastrula has cell layers that will later develop into different body structures. The three primary germ layers - ectoderm, mesoderm, and endoderm - are formed during gastrulation and give rise to various tissues and organs in the developing embryo.
Gastrulation is defined as a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a trilaminar structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm. These develop into the respiratory and digestive organs.
gastrulation
Three distinct layers form during gastrulation: ectoderm, mesoderm, and endoderm. Each contributes to different organs.Some examples are:Ectoderm = skin, brainMesoderm = kidneys, muscleEndoderm = digestive tract, respiratory tract
During gastrulation, two openings form in most animals. If the first opening becomes the mouth, the animal is a
