“The liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. Normally you can’t feel the liver, because it’s protected by the rib cage.”

HEALTHY LIVER LIVER DISEASED
The liver is an organ about the size of a football that sits just under your rib cage on the right side of your abdomen. The liver is essential for digesting food and ridding your body of toxic substances.
Liver disease can be inherited (genetic) or caused by a variety of factors that damage the liver, such as viruses and alcohol use. Obesity is also associated with liver damage.
Over time, damage to the liver results in scarring (cirrhosis), which can lead to liver failure, a life-threatening condition.
Cirrhosis is a complication of many liver diseases characterized by abnormal structure and function of the liver. The diseases that lead to cirrhosis do so because they injure and kill liver cells, after which the inflammation and repair that is associated with the dying liver cells causes scar tissue to form. The liver cells that do not die multiply in an attempt to replace the cells that have died. This results in clusters of newly-formed liver cells (regenerative nodules) within the scar tissue. There are many causes of cirrhosis including chemicals (such as alcohol, fat, and certain medications), viruses, toxic metals (such as iron and copper that accumulate in the liver as a result of genetic diseases), and autoimmune liver disease in which the body’s immune system attacks the liver.
The liver is an important organ in the body. It performs many critical functions, two of which are producing substances required by the body, for example, clotting proteins that are necessary in order for blood to clot, and removing toxic substances that can be harmful to the body, for example, drugs. The liver also has an important role in regulating the supply of glucose (sugar) and lipids (fat) that the body uses as fuel. In order to perform these critical functions, the liver cells must be working normally, and they must have a close proximity to the blood because the substances that are added or removed by the liver are transported to and from the liver by the blood.
The relationship of the liver to the blood is unique. Unlike most organs in the body, only a small amount of blood is supplied to the liver by arteries. Most of the liver’s supply of blood comes from the intestinal veins as the blood returns to the heart. The main vein that returns blood from the intestines is called the portal vein. As the portal vein passes through the liver, it breaks up into increasingly smaller and smaller veins. The tiniest veins (called sinusoids because of their unique structure) are in close contact with the liver cells. In fact, the liver cells line up along the length of the sinusoids. This close relationship between the liver cells and blood from the portal vein allows the liver cells to remove and add substances to the blood. Once the blood has passed through the sinusoids, it is collected in increasingly larger and larger veins that ultimately form a single vein, the hepatic vein, which returns the blood to the heart.
In cirrhosis, the relationship between blood and liver cells is destroyed. Even though the liver cells that survive or are newly-formed may be able to produce and remove substances from the blood, they do not have the normal, intimate relationship with the blood, and this interferes with the liver cells’ ability to add or remove substances from the blood. In addition, the scarring within the cirrhotic liver obstructs the flow of blood through the liver and to the liver cells. As a result of the obstruction to the flow of blood through the liver, blood “backs-up” in the portal vein, and the pressure in the portal vein increases, a condition called portal hypertension. Because of the obstruction to flow and high pressures in the portal vein, blood in the portal vein seeks other veins in which to return to the heart, veins with lower pressures that bypass the liver. Unfortunately, the liver is unable to add or remove substances from blood that bypasses it. It is a combination of reduced numbers of liver cells, loss of the normal contact between blood passing through the liver and the liver cells, and blood bypassing the liver that leads to many of the manifestations of cirrhosis.
A second reason for the problems caused by cirrhosis is the disturbed relationship between the liver cells and the channels through which bile flows. Bile is a fluid produced by liver cells that has two important functions: to aid in digestion and to remove and eliminate toxic substances from the body. The bile that is produced by liver cells is secreted into very tiny channels that run between the liver cells that line the sinusoids, called canaliculi. The canaliculi empty into small ducts which then join together to form larger and larger ducts. Ultimately, all of the ducts combine into one duct that enters the small intestine. In this way, bile gets to the intestine where it can help with the digestion of food. At the same time, toxic substances contained in the bile enter the intestine and then are eliminated in the stool. In cirrhosis, the canaliculi are abnormal and the relationship between liver cells and canaliculi is destroyed, just like the relationship between the liver cells and blood in the sinusoids. As a result, the liver is not able to eliminate toxic substances normally, and they can accumulate in the body. To a minor extent, digestion in the intestine also is reduced.

“Evidence is growing that regular physical activity reduces breast cancer risk, especially in women past menopause. The main question is how much activity is needed. Adults get at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity activity each week (or a combination of these), preferably spread throughout the week.”

Research shows that movement is vitally important, especially as we get older. Physical activity not only helps reduce the risk of cardiovascular disease, Type 2 diabetes and even some cancers, it also strengthens our bones and muscles. As we age, the health of our bones and muscles — known as our musculoskeletal system — is key to reducing the frequency and severity of common conditions such as back pain as well as preventing falls and other injuries that can lead to disability. For these reasons, it’s essential to move now, to move later…to move for life…to stay healthy and strong, active and engaged.
There are well over 100 types of adjustment techniques used by chiropractors throughout the world. Typically, chiropractors will focus on and utilize 8 to 10 different approaches in their practice.
The common goal of most chiropractic techniques is to restore or to enhance joint function, with the general goals of resolving joint inflammation and reducing pain. Some approaches use some force (spinal manipulation), while others are more gentle (spinal mobilization).

The common goal of most chiropractic techniques is to restore or to enhance joint function, with the general goals of resolving joint inflammation and reducing pain. Some approaches use some force (spinal manipulation), while others are more gentle (spinal mobilization).
The original chiropractic adjustment approach is generally referred to as spinal manipulation, and may also be called the diversified technique or the high-velocity, low-amplitude (HVLA) thrust. New chiropractic adjustment approaches typically evolve as a variation from an existing technique and are often named after the chiropractor who developed it.
This article reviews a number of the most commonly used spinal manipulation and spinal mobilization techniques currently used by chiropractors.
Spinal Manipulation (High-Velocity Low-Amplitude Thrust)
The most frequently used chiropractic technique, spinal manipulation, is the traditional high-velocity low-amplitude (HVLA) thrust. The manipulation often results in an audible “pop,” as chiropractors use their hands to apply a controlled sudden force to a joint while the body is positioned in a specific way.
Spinal Mobilization (Low-Force or Gentle Chiropractic Techniques)
Some conditions (such as osteoporosis), pathology, the patient’s size, patient comfort, or patient preference, may require a gentler approach generally referred to as spinal mobilization. In addition, some patients and/or clinicians prefer mild spinal mobilization techniques that do not involve twisting of the body or a forceful thrust.
n addition to manipulation, many chiropractors will employ adjunctive therapy, such as ice or heat or physical therapy modalities (such as electric stimulation, ultrasound, etc.), as part of an overall treatment plan. Patients should discuss their symptoms and preferences with their chiropractor, whose role it is to perform a thorough examination to determine the best course of treatment.
Chiropractors are not the only health care providers who utilize spinal manipulation for back pain treatment. Many osteopathic physicians will provide a variety of types of spinal adjustments, such as the spinal manipulation and mobilization described in this article. Occasionally, other types of health care professionals, such as physical therapists or physiatrists, will be trained in providing spinal manipulation as well.
The goal of spinal mobilization is the same as HVLA spinal manipulation – to restore or to enhance joint function. However, unlike HVLA spinal manipulation, slow movement, usually to a firm endpoint of joint movement, is used to mobilize the joint.
Chiropractors may choose spinal mobilization for certain patients for a variety of reasons, such as:
There is a wide range of spinal mobilization approaches and techniques. Several of the more common gentle spinal mobilization methods include:
“Our bodies have the capacity to do a little more than we normally do, but our bodies do not adapt very well to doing a lot more than we normally do. Since the added demands of this season can stress the capacity of our bodies, we need to do everything we can to help ourselves. Eat right, drink plenty of water, stretch, exercise, and take a few minutes to slow down and reflect on what the season is all about.”

“There are many types of breast cancer. The most common types are ductal carcinoma in situ, invasive ductal carcinoma, and invasive lobular carcinoma. The type of breast cancer is determined by the specific cells in the breast that are affected. Most breast cancers are carcinomas. Carcinomas are tumors that start in the epithelial cells that line organs and tissues throughout the body.”
