The structures that are fingerlike projections, and are continuous with the umbilical blood vessels, through which gases and nutrients are exchanged with maternal blood are indeed called villi.

These villi are part of the placenta, an organ that develops in the uterus during pregnancy. The villi increase the surface area of the placenta, allowing for efficient gas and nutrient exchange between the mother and the fetus.

Here's a step-by-step breakdown:

1. The umbilical cord connects the fetus to the mother's placenta.
2. The placenta contains villi, which are fingerlike projections.
3. These villi are filled with the fetus's blood and surrounded by the mother's blood.
4. Oxygen and nutrients from the mother's blood diffuse across the wall of the villi and umbilical blood vessels into the fetus's blood.
5. At the same time, waste products like carbon dioxide diffuse from the fetus's blood into the mother's blood through the same process.

This exchange allows the fetus to get the necessary nutrients and oxygen to grow and develop, while also removing waste products.
