Question

The placenta is described as a temporary structural and functional connection between which two circulations?

Options

• Systemic and pulmonary circulation

• Foetal and maternal circulation

• Portal and systemic circulation

• Umbilical and systemic circulation

Answer 1

The placenta serves as a temporary structural and functional connection between foetal and maternal circulation. This connection facilitates the exchange of gases, nutrients, hormones, and waste products between mother and foetus without direct mixing of blood. The placental barrier maintains separation while allowing selective, bidirectional transport of essential substances.
