Inside the Human Body
Today, Dr. Oz brought a selection of real healthy and damaged organs to demonstrate what goes on inside the human body. If you overeat, smoke or drink too much, you may be surprised to see what you're doing to your body.
The unhealthy heart (right) is larger and paler. The lighter spot in the middle indicates that this person had a heart attack. That scarred vessel was unable to bring blood to the heart, and the damage can be seen on the inside.
Once an artery is closed, it doesn't heal, which is a devastating problem, Dr. Oz says. While medicine has gotten better at curing heart attacks, damage is still done after a heart attack, creating an epidemic of heart failure.
The plaque that is created in the aorta is hard, like a rock, so it literally causes hardening. While plaque is dangerous, the possibility of a clot forming is even more worrisome. It is possible to reverse some of the effects of plaque on the aorta, but the best solution is prevention, says Dr. Oz.
The reason we get fat, Dr. Oz explained, is because our ancestors survived because they could store fat. In modern society, with no problems of food shortage, we're taking in more fat than we need to survive. By controlling your weight, Dr. Oz says, you can add years to your life.
The healthy liver is soft, smooth and supple. The unhealthy liver contains little nodules, which is an example of cirrhosis, caused by drinking too much alcohol. The liver serves to process all the materials you bring into your body, which it can't do if it's diseased.
The worst thing that can happen to your liver is cancer (right). When your liver becomes damaged, and the body is continually trying to repair itself, it can lead to cancer.
What's even more worrisome than tar, according to Dr. Oz, is cancer. A cancerous lung (right) will have nodules of cancer cells that grow and spread, invading into everything around them.
The knee (right), also has the meniscus to protect your joint. In an overweight person, it can get fractured and the bones begin to wear. This can lead to knee pain, back pain, and a number of orthopedic ailments.
To alleviate the problem, the gallbladder is often removed, which Dr. Oz says is one of the most common operations performed by doctors.
What diabetics can't see is how blood vessels can shrink, causing harm to the kidneys. On the left is a normal kidney; on the right, a damaged kidney. The good news is that Type 2 diabetes can be prevented through exercise and diet.
Dr. Oz calls the brain a "spectacular" organ that can actually shrink if you don't exercise it. What's the best way to do that?
"Daydream," says Dr. Oz. "You finally have an excuse!"
Dr. Oz says that if the tip of your tongue is too red, it could mean emotional or physical stress.
Unfortunately, stress can literally eat away at the body, says Dr. Oz. That's a leading cause of painful stomach ulcers, shown here at left. The black spots and discolored craters are signs of an overworked stomach. To protect your own stomach from these problems, try relaxing, stress-busting exercises like meditation.
Foods high in fiber include oatmeal, blueberries, brown rice, strawberries, carrots, beans, and peas.
Humans are the only mammals without a bone in their penises (right). This is because when men are sexually aroused, blood flows into the penis to make it stiff. That's another reason that men should exercise and eat well; doing so will keep the blood flowing throughout the entire body.
There is no known cause for uterine fibroids, and treatments may range from hormonal therapy to hysterectomy.
"When you manage stress better, when you exercise, when you eat better, your quality of life improves," he says. He suggests meditation as a way to reduce stress, adding that patients who meditate show improved medical tests.
