How does the placenta provide a large surface area for nutrient exchange?
The placenta contains blood spaces on the mother's side, surrounding the villi, which create a large surface area for glucose and oxygen to pass from the mother to the embryo.

Study Notes
Placenta and Embryonic Development
- The placenta provides a large surface area for nutrient exchange through the branching of chorionic villi, which increases the surface area for diffusion of oxygen and nutrients from the mother's blood to the fetus.
- The placenta serves as a crucial organ for embryonic development, providing the fetus with oxygen, nutrients, and waste removal, while also producing hormones to maintain pregnancy.
Placenta Structure
- The villi are located in the placenta, specifically in the chorion, which is the outermost layer of the placenta.
Birth Trigger
- The birth of the child is triggered by hormonal changes, specifically the increase in estrogen levels, which stimulate the contraction of the uterus and the onset of labor.
First World War
- The US entry into the First World War in 1917 had a significant impact on the outcome, as it shifted the balance of power in favor of the Allies, leading to the eventual defeat of the Central Powers.
- The Central Powers consisted of Germany, Austria-Hungary, and the Ottoman Empire.
- Germany made initial gains during the First World War, including the invasion of France and Belgium, and the capture of significant territory in Eastern Europe.
