Content: the lungs, the liver, the pancreas and the thyroid gland. The baby's eyes and inner ears are starting to develop. It is about now that your baby's major organs (heart, lungs liver, spleen, and kidneys) are beginning to develop. Your baby's digestive system is becoming more refined as the stomach and intestines develop. Remember the Folic Acid you should be taking? Well, since the Neural tube (later known as spinal cord) begins to fuse, folic acid is important in preventing neural tube defects. The embryo size is about a 1/8 inch (4mm) long. On the 26th day after fertilization, the embryo's tiny heart begins to beat. Other major organs, including the kidneys and liver, have begun to develop, and the neural tube, which connects the brain and spinal cord, closes. The physical sensations of pregnancy have started--nausea, fatigue, sore breasts and frequent urination.
