Snoring can be a Death Knell!

Elrod was the “cat’s meow” in high school. All around jock, great dancer, fun to be with, and always supplying beer for parties. He continued excelling at the latter part of “work hard / play hard” during college. Indeed, the homecoming queen fell in love with him when he said to her on their first date when he escorted her to her sorority’s formal dance: “I’ve got felines for you”. But happiness was to elude them given that Elrod never stopped his high school ways, especially the beer drinking. By age 30 he was overweight, and at night he kept the former queen awake with his snoring. At his annual physical his physician indicated there was little doubt but that Elrod was suffering from obstructive sleep apnea. The same examination also revealed he was suffering from cor pulmonale. His neck veins became engorged and highly visible even when at rest. His legs and belly were also swollen and he suffered from shortness of breath. At which indicated location do these engorged neck veins drain to normally?

Neck veins drain to which vessel/area?
