Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.

After the long winter, it’s nice to have the getfit program to give me the momentum to be more active. The support of the getfit network helps me to be more mindful and more conscious, and the discounts and perks are wonderful incentives. The support does not end when you leave campus—getfit links to an array of fitness programs both on campus and in the community. Meeting new people while taking a power walk around the Charles, through the tunnels, or in after-work activities is an added bonus.
