Within the cardiovascular system are several important parts of the circulatory system. They include two major organs‚ the heart and lungs.

Veins‚ in contrast‚ are subjected to much lower pressures and have thinner walls overall‚ with the tunica adventitia often outsizing the tunica media. Because thinwalled veins conduct blood back to the heart against gravity‚ valves (not present in arteries) also are present at intervals to
