Pig Embryo (stage 13/14)

In this class we will follow the path of oxygenated blood through the embryo then look at the passage of venous blood through the cardinal veins.

At this stage of development the embryo trunk consists mainly of heart, liver and embryonic kidney.

Each image is an excerpt from the complete st13/14 Pig embryo and should also be looked at in the entire slice, to see the relationship of vasculature with other developing systems.

Note that some images contain identifying labels that appear at the bottom of the browser window when the computer mouse/pointer passes over them.
