Answer:

Explanation:

Vestigial structures are cells, tissues, and/or organs that have no apparent function. Vestigial structures are retained during the course of the evolution, but often they are degenerate and/or atrophied (due to disuse). In general, these structures are homologous to anatomical structures that play a specific role in evolutionarily related species. Some examples of vestigial structures include, among others, the presence of the appendix in humans and wings in flightless birds.

in the system labels B in figure 27-11, where does oxygen-poor blood go after leaving the heart? Why?

Once the blood is oxygenated, it goes back into the heart, to be pumped back into our bodies for distribution.
