What changes take place in the fetal circulation with the newborn’s first few respirations?
With the newborn’s first few respirations, the lungs expand as soon as the pressure within the chest alters. The foramen ovale closes, and the ductus arteriosus and ductus venosus shrivel up and become fibrous ligaments.
How is fetal circulation different from adult circulation?
In fetal circulation, the placenta returns deoxygenated blood from the fetus to the mother through the two umbilical arteries. The placenta returns oxygenated blood to the fetus via a single vessel, the umbilical vein. In adult circulation, all arteries carry oxygenated blood, and all veins carry deoxygenated blood.

Nausea or vomiting during pregnancy may happen at any time during the day. If this condition lasts beyond the fourth month, results in a weight loss of 8 pounds or more, or affects the woman’s general health, it is considered a complication of pregnancy known as hyperemesis gravidarum.
What is quickening, and when is it first experienced?
