A fetus's heart beats slowly compared to an adult's heart rate due to its developmental stage and the lower metabolic demands of the fetal environment. In the womb, the fetus relies on the placenta for oxygen and nutrients, which reduces the need for a higher heart rate. Additionally, the fetal heart's structure and function are adapted to support growth and development rather than the demands of independent living. As the fetus matures, its heart rate typically increases in response to growth and activity levels.
