Lobule

A lobule is a small structural unit of an organ or part of it, which is delimited from other areas, for example, by a septum. This border may or may not be visible under a microscope.

For example, the liver lobule is a structural and functional unit, distinguishable in a cross-section of the liver under a microscope as columns of cells that converge towards the central vein and are associated with the branches of the portal vein.

The lung lobule is clearly visible when directly examining a section of the lung. It has the shape of an irregular pyramid and is separated from other lobules by interlobular connective tissue septa. The lung lobule consists of 3-5 pulmonary acini.

Thus, the lobule is an important structural unit of organs, allowing the identification of individual functional areas. Studying the structure of the lobules provides important information about the microstructure and function of organs.

A lobule is a small structural unit of an organ or part of it, separated from other parts by a septum. It may or may not be visible under a microscope and is a functional unit that performs specific tasks in the body. In this article we will look at two examples of lobules: the liver lobule and the lung lobule.

The lobule of the liver is a structural and functional unit visible in a cross section of the liver under a microscope. It consists of columns of cells that converge towards the central vein and are connected to the branches of the portal vein. Each liver lobule is shaped like a hexagonal prism and measures approximately 1-2 mm in diameter. It performs many functions, including processing the blood that comes from the portal vein and liver artery and secreting bile.

The lobule of the lung (lung lobule) is clearly visible when directly examining a section of the lung. It is shaped like an irregular pyramid and consists of three to five pulmonary acini, which are the functional units of the lung. The acini is a structural unit of the lung in which gas exchange occurs between blood and air. The lobules of the lung are separated from each other by interlobular connective tissue septa. They perform an important function in the breathing process, ensuring the transfer of oxygen into the body and the removal of carbon dioxide from it.

In conclusion, a lobule is a small structural unit that is the functional unit of organs and performs important tasks in the body. The liver and lung lobules are two examples of lobules that play a key role in ensuring the normal functioning of these organs. Studying the lobules and their functions helps to better understand the anatomy and physiology of the body and can be useful in the diagnosis and treatment of various diseases.

A lobule (from Latin lobulus - “small tubercle”) is a small structural unit of an organ, which is limited from its other parts. Depending on the organ, the lobule may have a different shape and structure.

In the liver, a lobule is a structure that consists of columns of cells converging towards the center of the liver, where the central vein is located. The boundary between the lobules may or may not be visible under a microscope.

Similarly, in the lungs the lobule is pyramid-shaped and consists of several pulmonary acini separated by interlobular septa.

Thus, the lobule is an important structural unit of organs, which plays an important role in their functioning and structure.
