The fetal circulation is the circulatory system of a human fetus, often encompassing the entire fetoplacental circulation that also includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.

The fetal circulation works differently from that of born humans, mainly because the lungs are not in use: the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.

atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present from birth (congenital). Small atrial septal defects may close on their own during infancy or early childhood. Large and long-standing atrial septal defects can damage your heart and lungs. Small defects may never cause a problem and may be found incidentally.

This presentation discusses in detail, the causes of these underlying conditions. Also mentioned are the clinical features and management options and therapeutic sodium targets in patients with hyponatremia.
