Week 21


Anna’s blood circulation is completely functional. The umbilical cord system continues to grow and thicken as blood travels with considerable force through the body to nurture her.

She will be getting much larger during the second half of the pregnancy. Her crown-to-rump length at this time is 7.2 inches and she weighs approximately 10.5 ounces. She is about the size of a large carrot.

Her different organs and systems are maturing. The fetal digestive system is functioning in a simple way and she can swallow amniotic fluid. After Anna swallows the amniotic fluid, she is able to absorb water and sugars from the fluid and then the waste is passed as far as the large bowel. She swallows the amniotic fluid in order to prepare herself for life outside of the womb. Some babies consume as much as 17 ounces of amniotic fluid in a 24-hour period. She already has a high number of red blood cells and the white blood cells are beginning to be produced. Taste buds are being formed on her tongue this week also.
