Recall that in humans, as cells begin to differentiate, they form a hollow ball made up of cells called a blastocyst. The blastocyst Will eventually form three distinct layers of cells, sometimes referred to as germ layers. The three germ layers are the ectoderm, the endoderm, and the mesoderm. Evaluate the statements below and select the one that correctly describes which body systems and organs each of the three germ layers will become.The ectoderm will become the outer skin and the parts of the nervous system such as the spinal cord and brain. The mesoderm will differentiate into many of the internal organs, such as the pancreas, lungs, and part of the digestive system. The endodermal differentiate into the bones, muscles, and kidneys.The mesoderm will become the outer skin and part of the nervous system, such as a spinal cord and brain. The endoderm will differentiate into many of the internal organs such as the pancreas, lungs, and part of the digestive system. The ectoderm Will Differentiate into the bones, muscles, and Kidneys. The ectoderm will become the outer skin and parts of the nervous system, such as the spinal cord and brain. The endoderm will differentiate into many of the internal organs, such as the pancreas, lungs, and parts of the digestive system. The mesoderm will differentiate into the bones, muscles, and kidneys. The endoderm will become the outer skin and parts of the nervous system, such as the spinal cord and brain. The ectoderm will differentiate into many of the internal organs, such as the pancreas lungs and part of the digestive system. The mesoderm will differentiate into the bones, muscles, and kidneys.
