Answer: Pulmonary veins
Explanation:
Highly oxygenated blood returning from the pulmonary capillaries in the lungs passes through a series of vessels that join together to form the pulmonary veins—the only post-natal veins in the body that carry highly oxygenated blood. The pulmonary veins conduct blood into the left atrium, which pumps the blood into the left ventricle, which in turn pumps oxygenated blood into the aorta and on to the many branches of the systemic circuit.
In this case, oxygen and nutrients exit the systemic capillaries to be used by the cells in their metabolic processes, and carbon dioxide and waste products will enter the blood.

In the pillbug experiment, if the pillbugs in the experimental chamber would have moved to the side of the chamber with sand instead of cornstarch then the Pillbugs tend to prefer sand over cornstarch.
Pillbugs are categorised as terrestrial isopods and are in the crustacea family. The purpose of this experiment is to determine if pillbugs, often known as roly-polys, prefer light or darkness. They are cold-blooded, slow-moving organisms whose environs control their body temperatures.
The pill bugs are the controlled variable, and the behaviour of the pillbug is the dependent variable. The experimental group is housed in a moist environment with water and cornstarch, whereas the control group is in a dry environment with sand.
