What is the approximate blood volume of a fetus?

The approximate blood volume of a fetus is typically around 250 mL. This volume is crucial as it plays a significant role in fetal development and overall physiological functions. The blood volume in a fetus is essential for ensuring adequate nutrient and oxygen delivery, waste removal, and maintaining proper hemodynamics during gestation.

As a fetus grows, its blood volume increases, and it is generally estimated that at full term, the blood volume represents about 10% of the body weight of the baby. This protective and functional aspect is vital as the fetus relies on maternal circulation for many of its needs prior to birth.

Understanding fetal blood volume can also be important for midwives and healthcare providers when assessing fetal well-being and planning for labor and delivery. Having adequate knowledge in this area helps ensure that newborns transition smoothly to independent life post-delivery.
