Final answer:
A fetus can produce urine, which is true, and this plays an important role in the amniotic fluid composition and fetal development. The statement that the umbilical artery carries oxygenated blood to the fetus is false; instead, it transports deoxygenated blood away from the fetus.
Step-by-step explanation:
When it comes to the statement that a fetus can produce urine, the answer is True. Fetal development involves the formation of the urinary system, and fetuses are capable of producing urine from early in the second trimester. They release this urine into the amniotic fluid, which plays a critical role in fetal development, particularly in lung maturation.
Regarding the role of the umbilical artery, it's False to say that the umbilical artery carries oxygenated blood to the fetus. In fact, it's the opposite. The umbilical arteries carry deoxygenated blood away from the fetus towards the placenta, where gas exchange occurs. The oxygenated blood is then returned to the fetus via the umbilical vein.
