Pulmonary and Venous Disorders: Introduction

"The risk of a DVT occurring on a flight lasting more than four hours is between 1 in 4,650 flights and 1 in 6,000 flights."

Your lungs have many functions in your body beyond just oxygenating your blood. One of their other important roles is filtering the venous blood that returns from the body. The venous system is characterized by slower blood flow than the arterial system, which contributes to the occasional formation of a blood clot (known as a "peripheral venous thrombosis"), which could be transported into the lungs and could even cause a pulmonary embolism (or blockage in the vessels of the lungs).
