Your fetusâ€™ body is continually developing. Hereâ€™s whatâ€™s happening this week! The placenta, which nourishes your fetus and also removes waste, is ever growing to accommodate your babyâ€™s needs. It now contains thousands of blood vessels, which bring life-giving oxygen and nutrients to your little one. Plus, the umbilical cord, which is your babyâ€™s lifeline to the placenta, is growing stronger and thicker. Your babyâ€™s umbilical cord contains two arteries and one vein surrounded by a white thick gel called Whartonâ€™s Jelly. Your fetus weighs about five ounces, and measures five inches now, making your little one the size of a sweet potato! Interestingly, your babyâ€™s bones have started to ossify, which means to change from what was previously soft cartilage to what will become hard bone. Some of the first bones to ossify are those in the clavicles and legs. Plus, your babyâ€™s sweat glands are forming now, and your little oneâ€™s joints are now fully active and moving. To see what your fetus is up to next week, check back for a brand new video update!
