Prostaglandins may be given to permit the oxygenated blood and deoxygenated blood to mix by keeping the ductus arteriosus open. Developing endocardial cushions is essential in understanding why certain cardiac defects develop. The rectus abdominus helps support the body and hold the mid-section of the body together. From the IVC, blood travels through the right atrium of the heart to be directed across a shunt into the left atrium. It is comprised of the blood vessels in the placenta and the umbilical cord, which contains two umbilical arteries and one umbilical vein. Cyanotic heart defects are typically from right-to-left shunts in blood after birth. The mother's uterusfosters the environment for fetal growth and placental vitality.
