It is amazing to read how the baby is growing. Today the baby is the size of a pinto bean. The eyelid folds are forming on the face and nerve cells in the retina are beginning to develop. The tip of the nose is present. Ears are forming, internally and externally. In the heart, the aortic and pulmonary valves are present and distinct. Elbows are present, and the arms and legs extend forward. Arms have grown longer. The bend at the elbows and curve slightly over the heart. Tubes leading from the throat to the functioning part of the lungs are branched, like the branches of a tree. The body's trunk area is getting longer and straightening out.
