The baby is quarter of an inch long. The nose, mouth, jaw and ears are taking shape. The face has dark spots where the baby’s eyes and nostrils are starting to form. The ear canals are marked by small depressions on the sides of the head. An opening for the mouth is formed by the growth of tissue from above and from the sides of the face. Below the mouth are small folds that ultimately will develop into your baby’s neck and lower jaw. His arms and legs are starting to protrude. His heart is beating 100+ times a minute. Blood is beginning to flow through his body. His kidneys, intestines, liver and lungs are developing. His pituitary gland is developing, as are the rest of his brain, muscles, and bones. The hand and feet have webbed structures which will become fingers.
