How serious is the shortage of general surgeons in the U.S.?
Arthur Perry, MD, Plastic/reconstructive Surgery, answeredThe shortage of general surgeons in the US is reaching a crisis point -- a third of rural hospitals do not have a general surgeon that lives in the same county as the hospital. Surgical emergencies require rapid trips to the operating room, and that is why the best hospitals have in-house general surgeons. But these are few and far between. Most do not. And as the shortage of general surgeons deepens, less will have that luxury. And that means when you wind up in a ditch on the side of the road in a rural area, you may be out of luck. And when you get that unbearable belly pain in the middle of the night that can only be fixed with the scalpel, or you need your spleen taken out because you just fell off your roof, you might not find a general surgeon in your hospital -- and that may cost you your life.
Why do our hearts have four chambers?
Michael Roizen, MD, Internal Medicine, answeredAs the heart develops in the unborn child, it takes on several distinct appearances, each resembling other animal hearts and each a step higher on the evolutionary ladder. At first, the tube-like heart is much like a fish heart. When it divides into two chambers, it is similar to a frog heart; with three chambers, a snake or turtle heart. Finally, with four chambers, the fully formed heart looks like what it is: the heart of a human being, the most highly evolved mammal.
The four-chambered heart has a distinct advantage over simpler structures: It allows us to send our "dirty" blood to the cleaners-the lungs-and our "clean" blood to the rest of the body without having to mix the two. That system is very efficient. The blood coming from the left side of the heart is pure, fully oxygenated, and ready to fuel the muscles. A fish heart, on the other hand, has to pump blood, which is only half as pure, to the body because it doesn't have separate chambers that enable it to clean the blood in one cycle and distribute it in the next.
Our sophisticated ticker allows us to process energy more efficiently and, therefore, move further from our energy source. We can do lots of work in between looking for food, while a fish has to live in its energy source, eating all the time.

What is a cardiovascular surgeon?
Cardiovascular surgeons are medical doctors who specialize in surgery of the heart and blood vessels. They generally perform heart surgeries and treat people who have a blockage in the blood vessels leading to the heart (coronary artery disease) or problems with heart valves.
Cardiovascular surgeons may further specialize in treating people of specific age groups, such as pediatric cardiovascular surgeons, who only treat children and often treat heart problems related to birth defects.
Cardiovascular surgeons can be board-certified by the Board of Surgery in general surgery or vascular surgery. The Board of Surgery is recognized by the American Board of Medical Specialties.
