Is a liver lobe the same as a liver lobule?
The lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein. Lobules are different from the lobes of the liver: they are the smaller divisions of the lobes. The two-dimensional microarchitecture of the liver can be viewed from different perspectives: Name Shape Model classica

The free, inferior border of the falciform ligament contains the paraumbilical veins and the round ligament of the liver (aka, ligamentum teres hepatis) which courses along a fissure situated between the inferior surface of the right and left lobes.
How many ligaments are present in liver?
It consists of four lobes and two major surfaces. Because it is such a large organ, it requires seven ligaments to keep it relatively immobile in its anatomical location. The largest of the seven hepatic ligaments is the coronary (coronal) ligament.
What is ligamentum teres?
However, the ligamentum teres is a strong intraarticular ligament that is anatomically and biochemically similar to the anterior cruciate ligament of the knee. It is composed of two bands that originate from the acetabular transverse ligament and the pubic and ischial margins of the acetabular notch.
What are ligaments?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.

The free edge of this ligament contains the ligamentum teres, a remnant of the umbilical vein.
What are the two surfaces of the liver?
There are two liver surfaces – the diaphragmatic and visceral: Diaphragmatic surface – the anterosuperior surface of the liver. It is smooth and convex, fitting snugly beneath the curvature of the diaphragm.
What is the liver covered by?

The posterior and superior extension of the hepatogastric ligament (lesser omentum) branches, reflects on itself and becomes continuous with the liver capsule. As it branches to the right it reflects on itself, becomes continuous with the liver capsule and becomes the right inferior coronary ligament.
What is the union of the right and left triangular ligaments?
On the right the union is called the right triangular ligament. On the left the left triangular ligament extends toward and attaches to the diaphragm to end in a large fold and a strong fibrous band called the a ppendix fibrosa hepatis.
What is the ligamentum teres?

Why is the liver important?
The liver is a special organ in the sense that it receives more venous blood than arterial blood and this is due to the fact that the liver helps clean the blood via detoxification. The majority of the vascular supply is brought into the organ by the portal vein which carries the blood filled with metabolytes absorbed in the intestines, whereas the rest of the blood comes from the common hepatic artery which originates from the celiac trunk and carries the oxygenated blood to the liver.

The deep system consists of hepatic lymph vessels which follow the hepatic portal veins, therefore most of the lymph will flow towards the hepatic nodes at the hilum of the liver, which drain to the celiac nodes.
What is the liver?
The liver is reddish-brown and shaped approximately like a cone or a wedge, with the small end above the spleen and stomach and the large end above the small intestine. The entire organ is located below the lungs in the right upper abdomen. It weighs between 3 and 3.5 pounds.

Falciform Ligament: A thin, fibrous ligament that separates the two lobes of the liver and connects it to the abdominal wall. Glisson’s Capsule: A layer of loose connective tissue that surrounds the liver and its related arteries and ducts.
How many lobes are there in the liver?
The liver consists of four lobes: the larger right lobe and left lobe, and the smaller caudate lobe and quadrate lobe. The left and right lobe are divided by the falciform (“sickle-shaped” in Latin) ligament, which connects the liver to the abdominal wall. The liver’s lobes can be further divided into eight segments, which are made up of thousands of lobules (small lobes). Each of these lobules has a duct flowing toward the common hepatic duct, which drains bile from the liver.
What are the functions of the liver?
The liver is an essential organ of the body that performs over 500 vital functions. These include removing waste products and foreign substances from the bloodstream, regulating blood sugar levels, and creating essential nutrients. Here are some of its most important functions: 1 Albumin Production: Albumin is a protein that keeps fluids in the bloodstream from leaking into surrounding tissue. It also carries hormones, vitamins, and enzymes through the body. 2 Bile Production: Bile is a fluid that is critical to the digestion and absorption of fats in the small intestine. 3 Filters Blood: All the blood leaving the stomach and intestines passes through the liver, which removes toxins, byproducts, and other harmful substances. 4 Regulates Amino Acids: The production of proteins depend on amino acids. The liver makes sure amino acid levels in the bloodstream remain healthy. 5 Regulates Blood Clotting: Blood clotting coagulants are created using vitamin K, which can only be absorbed with the help of bile, a fluid the liver produces. 6 Resists Infections: As part of the filtering process, the liver also removes bacteria from the bloodstream. 7 Stores Vitamins and Minerals: The liver stores significant amounts of vitamins A, D, E, K, and B12, as well as iron and copper. 8 Processes Glucose: The liver removes excess glucose (sugar) from the bloodstream and stores it as glycogen. As needed, it can convert glycogen back into glucose.
What does the liver store?
Stores Vitamins and Minerals: The liver stores significant amounts of vitamins A, D, E, K, and B12, as well as iron and copper. Processes Glucose: The liver removes excess glucose (sugar) from the bloodstream and stores it as glycogen. As needed, it can convert glycogen back into glucose.
How to avoid liver disease?
The best way to avoid liver disease is to take active steps toward a healthy life. The following are some recommendations that will help keep the liver functioning as it should: Avoid Illicit Drugs: Illicit drugs are toxins that the liver must filter out.

Which part of the liver transports bile?
The common hepatic duct transports the bile made by the liver cells to the gallbladder and duodenum (the first part of the small intestine) via the common bile duct.
What happens when the liver breaks down harmful substances?
When the liver has broken down harmful substances, its by-products are excreted into the bile or blood. Bile by-products enter the intestine and leave the body in the form of feces. Blood by-products are filtered out by the kidneys, and leave the body in the form of urine.
How does the liver help the body?
This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

How does the liver resist infections?
Resisting infections by making immune factors and removing bacteria from the bloodstream. Clearance of bilirubin, also from red blood cells. If there is an accumulation of bilirubin, the skin and eyes turn yellow. When the liver has broken down harmful substances, its by-products are excreted into the bile or blood.
