from Section 7 - Placenta
Published online by Cambridge University Press: 20 November 2021
The placenta is a unique organ of pregnancy that plays a key role in the normal development and normal growth of the fetus. It creates the intrauterine environment, which, as we know today, has a long-term impact on the health of the developing human being. Its ability to take over functions of the liver, lung, gastrointestinal tract, kidneys and endocrine organs illustrates its multi-organ function. The placenta has two main components – one is of maternal origin, one belongs to the fetus – and interaction between these two parts needs to be optimal for a successful pregnancy, controlling optimal exchange of nutrients, oxygen and removal of carbon dioxide. This chapter will give further insight into the structure, blood supply and metabolic transfer of the normal placenta and will present today’s concepts of its role in long-term health.
