Fetal Circulation Diagram - Anatomy and Blood Flow Pathways #1985443 (License: Personal Use)

This anatomical diagram depicts the unique fetal circulatory pathway where oxygenated blood from the placenta enters via the umbilical vein, bypasses the liver through the ductus venosus, and reaches the heart via the inferior vena cava. From there, most blood crosses the foramen ovale into the left atrium to supply the brain and heart, while deoxygenated blood exits via the umbilical arteries. The aorta, lungs, liver, intestines, kidneys, and hindlimbs & tail are labeled to show regional perfusion patterns.

Used in medical education, obstetrics, and developmental biology resources to teach how fetal circulation differs from postnatal circulation; supports understanding of congenital heart defects and transition at birth.
