Question

Quizplus · Accepted Answer

The volume of amniotic fluid increases after the first trimester due to production of fetal urine. As the kidneys of the fetus develop and begin to function, they produce urine which is released into the amniotic fluid. This urine makes up a significant portion of the amniotic fluid volume, and as the fetus grows and develops, the volume of urine increases, leading to an overall increase in the volume of amniotic fluid.
