What Are Two Functions Of The Liver – The liver is vital for the healthy functioning of the human body. It is involved in the body’s three main vital functions, including storage, purification and synthesis. A healthy liver helps improve digestion, removes toxins and other impurities from the body, regulates blood clotting, removes bacteria from the blood, and maintains hormone balance.
Maintaining a healthy liver is important for good health. Liver function tests (LFTs), which are a series of blood tests, can help you determine the health of your liver. They help detect inflammation or other liver damage by detecting levels of proteins or enzymes in the blood.
What Are Two Functions Of The Liver
Alanine transaminase (ALT) test: This test is done to determine the level of ALT in the body. A high level of ALT in the body is a sign of liver damage.

Albumin test: This test helps determine how well your liver is working by measuring the level of albumin in your body. Albumin is the main protein produced in the liver. Low albumin levels indicate that the liver is not working properly.
Bilirubin Test: Bilirubin is a waste product that is processed by the liver. A bilirubin test can measure the level of bilirubin, which helps determine liver health. High levels of bilirubin in the body mean that the liver is not working properly.
There are two other LFTs, including the aspartate transaminase (AST) test and the alkaline phosphatase (ALP) test, which are done along with other tests to measure liver health.
Your doctor may order LFTs if you have symptoms such as weightlessness, weakness, nausea, vomiting, jaundice, diarrhea, abdominal pain

And others. Several diseases can be detected using LFT. They include:
Your doctor may ask you to avoid eating or taking any medications before the test. A phlebotomist (a person trained to draw blood for tests) sterilizes the hand to prevent tampering with the test. He then wraps a device around your arm that makes your veins visible. Blood is then withdrawn using a needle. After drawing the appropriate amount of blood, the phlebotomist places a bandage over the blood draw.
At Narayana Health, our efficient and experienced team performs LFTs to determine the health status of your liver. A nutritious diet and an active lifestyle can help you maintain liver health.

The liver is a large organ located in the upper right quadrant of the abdomen. It is a multifunctional accessory organ of the digestive tract and performs several important functions such as detoxification, protein synthesis, bile production and nutrient storage to name a few. It is the largest gland in the human body, weighing about 1.5 kilograms. It works synchronously with many other organs and contributes to the maintenance of basic homeostatic mechanisms.
Liver Function Tests: Uses, Side Effects, Procedures
The liver is completely covered by the visceral peritoneum except for the bare area where the liver meets the diaphragm.
Superficial system (lymphatic vessels in subserosal areolar tissue) Deep system (lymphatic vessels in liver contents)
There are four anatomical lobes, which are divided into even smaller segments according to the blood supply of the liver.
The right lobe is the largest of the four lobes and the left lobe is the smaller, flattened one. These two lobes are separated by the gallbladder recesses and the inferior vena cava.

The scapular lobe is located between the cleft of the ligamentum venosus and the inferior vena cava, while the quadrate is between the gallbladder and the cleft of the ligamentum teres hepatis.
The two main surfaces of the liver are the diaphragmatic surface and the visceral surface. The latter is covered by the visceral peritoneum, except for the porta hepatis and the base of the gallbladder. This surface is directly connected to several anatomical structures, including:
The surface of the diaphragm rests against the lower surface of the diaphragm and is also covered by the visceral peritoneum, except for the bare area.
The porta hepatis is the central intraperitoneal fissure (on the visceral surface) of the liver that separates the caudate and quadrate lobes. It is the entry and exit point for several important structures, including the portal vein, hepatic arteries, hepatic ducts, hepatic plexus, and lymphatic vessels.

The subphrenic fossa is the space between the diaphragmatic surface of the liver and the lower surface of the diaphragm; it is divided into right and left zones by the falciform ligament of the liver.
The hepatorenal fossa is a space located on the lower right side of the liver, between this organ and the right kidney and adrenal gland.
The deep system consists of hepatic lymphatic vessels that follow the portal veins of the liver, so that most of the lymph flows into the hepatic nodes in the hilum of the liver, which drain into the celiac nodes. They drain into the cisterna chilli (if present) and into the thoracic duct. Additional lymphatic vessels exit the bare area after the hepatic veins as they join the inferior vena cava. Therefore, some of the hepatic lymph nodes drain into the inferior diaphragmatic/phrenic nodes (or the upper limbs of the right lumbar lymph nodes), which drain into the right posterior mediastinal nodes. From there, the lymph flows through the lymphatic chain of the right mediastinum and flows into the lymphatic channel, i.e. the right chest channel.
The superficial system transports lymphatic fluid through the ducts of the subserosal areolar tissue (Glisson’s capsule) that surrounds the liver. The lower, front and upper surface drain into the nodes of the liver, the hilum of the liver. The right upper surface often drains into lymphatic vessels, following the inferior renal artery and connecting with the celiac nodes. The posterior surface of the liver is directed to the bare area of the liver and the inferior diaphragmatic nodes/right lumbar nodes, which drain as described above.
Liver Function Test (lft)
The liver is a special organ because it receives more venous blood than arterial blood as it helps to purify the blood through detoxification. Most of the blood vessels reach this organ through the portal vein, which carries blood from the digestive tract full of absorbed metabolites to the intestines. The rest of the blood supply to this organ comes from the common hepatic artery, which originates in the celiac artery and carries oxygenated blood to the liver.
The hepatic veins are formed by the union of the central veins. They direct blood from the liver directly into the inferior vena cava just before passing through the diaphragm.
The nerve supply to the liver originates from the hepatic plexus, which travels with the hepatic artery and portal vein. The liver also receives sympathetic fibers from the celiac plexus and parasympathetic fibers from the anterior and posterior vagal trunks.
The liver is an important organ responsible for several vital functions, including metabolism, immunity, digestion, detoxification, and vitamin storage. It is responsible for producing bile, which aids in the digestion and absorption of lipids (or fats), as well as storing and metabolizing fat-soluble vitamins. This organ is crucial in the metabolism or detoxification of various chemical substances such as drugs. It is responsible for the metabolism of bilirubin, which results from the breakdown of heme in red blood cells. The liver is also involved in the metabolism of thyroid hormones. Finally, it is the site of synthesis of basic plasma proteins such as albumin and clotting factors.
Liver Conditions Linked To Ulcerative Colitis
Blood tests are done to evaluate liver hepatocyte function and bile secretion if one or more of these signs are present. The most common liver diseases are liver failure, cirrhosis, portal hypertension and cholestasis.
