human organs
The human body is made up of cells like the rest of the living organisms. The cell is a label for the body building unit, which is named by the name Robert Hook. The human body has many types of cells. Cells form each species, and how many cells are different. Together, vital organs have important functions in the body, including the heart. For example, several members come together to form a device, and the organ may be involved more than one organ; to multiply its functions, such as: the intestine that is a member of the two organs: the output, the digestive. The organs of the body have great importance within the human body, and these members: kidney, liver, spleen, lungs, stomach, and other organs.
The presence of liver in the human body
The liver is located in the upper quadrant of the right side of the abdomen, specifically the bottom of the diaphragm, the right side of the stomach, the right kidney, the intestines, its color is brown, tends to pale red, and has multiple functions. The liver is divided into two lobes; each consists of eight connected pieces, consisting of small lobules of up to 1,000 lobules, connected by small channels connected to other large channels; eventually forming the hepatic channel, Resulting in gallbladder and the first twelve small intestine parts. Liver weight in adult males usually ranges from 1.4 to 1.5 kg. In females, it is 1.2 to 1.4 kg. It is the largest internal organ, the largest gland in the human body. It is linked to two large blood vessels, A blood-laden liver with oxygen from the aorta, and a blood-borne portal with nutrients digested from the entire digestive system, spleen, and pancreas.
Liver function
The lobules in the liver are functional units; in each lobster millions of hepatic cells are connected together by the connective connective tissue that extends into the liver through the veins and arteries. This is why the liver functions very important to the body, including:
- The production of bile or gall bladder juice daily, a basal fluid stored in the gallbladder, helps to get rid of waste, and dissolving fat in the intestines.
- Producing keratin proteins for plasma blood.
- Producing cholesterol, in addition to special proteins that help to transfer fat in the body.
- Store glucose in the form of glycogen, and release it as needed by the body.
- Transform harmful ammonia into urea, and remove it with urine.
- Purification of blood from chemicals resulting from the intake of drugs, and toxic substances to the body.
- Regulation of blood clotting.
- Resist foreign objects, including harmful bacteria, by producing different immune factors.
- Remove the damaged red blood cells by removing the bilirubin with the yellow substance; the blood coming from the stomach and intestine passes through the liver.
- Storage of vitamins, disassembly of toxic substances, such as: alcohol, and pharmaceutical products.
Liver diseases and symptoms
Diseases
The liver can infect many diseases that negatively affect its work, including:
- Hepatitis: There are several types of the disease, depending on the type of the virus: A, B, C, D, E, and often transmitted through infection of viral blood contaminated, or contaminated food and water, and C (B,) and the most dangerous and widespread, Together cause hundreds of millions of people with chronic liver disease, the two most common causes of cirrhosis and liver damage. The disease causes: jaundice, severe fatigue, abdominal pain, nausea, vomiting, and urine retention, and if untreated may cause death.
- Budd Kyari syndrome: This syndrome is caused by the obstruction of liver veins entering the liver, causing abdominal pain, and liver enlargement.
- Hepatic Cirrhosis: This disease results in slow destruction of the bile duct, leading to a high level of cholesterol in the body, and is a disease of autoimmune diseases; it attacks the body itself, and cause damage channels, leading to cirrhosis, and liver failure in the event of the development of the disease, The disease is the accumulation of yellow matter in the liver, and a complete imbalance in its function, and affects the disease extensively women over 50 years.
- Liver Cancer: Is one of the common types of malignant cancers. The disease is caused by smoking, alcoholism, obesity, diabetes, and liver cirrhosis. Liver disease is different from the disease, showing signs of loss of appetite, weight, fatigue and jaundice. Some patients tend to remove the diseased portion of the liver. Less than half of the liver can survive. If completely removed, the patient may undergo liver transplantation.
Symptoms
Symptoms of a previous disease are: high body temperature, loss of appetite, general fatigue in the body, vomiting, pain in the upper right quadrant caused by liver enlargement, nausea, and joint and bone pain; loss of calcium , Jaundice (yellowish skin), and dark urine. The doctor performs a variety of different tests to determine the severity of these symptoms, such as: blood tests, or radiation; to produce a picture of the liver, or by scanning or radiography.
