Circulation

4. The remnant of the foramen ovale in the adult heart
6. Higher in fetal blood returning from the placenta than in adult venous blood.
8. The chamber of the heart that pumps oxygenated blood into the aorta.
11. A fetal blood vessel that connects the pulmonary artery to the aorta, bypassing the lungs
12. The process of fetal circulatory structures closing and adapting to postnatal life.
14. The pathway that delivers oxygenated blood from the heart to the body and returns deoxygenated blood.
16. A condition where the fetal opening between the atria fails to close after birth.
18. An opening between the right and left atria in the fetal heart that allows blood to bypass the lungs
20. The vessels that carry oxygenated blood from the lungs to the heart.
21. The remnant of the ductus arteriosus in the adult circulatory system.
22. Sensory receptors in arteries that detect changes in blood pressure.
23. The event that triggers the closure of fetal shunts and transition to independent lung function
24. The primary organ for oxygen exchange after birth

1. The remnant of the ductus venosus in the adult liver
2. The chamber of the heart that receives deoxygenated blood from the body.
3. The circuit that carries blood between the heart and lungs, fully functional after birth.
5. The organ that facilitates gas, nutrient, and waste exchange between the mother and fetus
7. A condition where the ductus arteriosus remains open after birth.
9. has a higher affinity for oxygen compared to adult hemoglobin.
10. The fetal vessels that return deoxygenated blood to the placenta.
13. The largest artery in the body that distributes oxygenated blood to systemic circulation.
15. The major vein that carries deoxygenated blood from the lower body to the heart
17. A fetal blood vessel that directs blood from the umbilical vein to the inferior vena cava, bypassing the liver.
19. The vessel that carries oxygenated blood from the placenta to the fetus.
