Gate (Hilum, Pl. Hila)

Gate (Hilum) is a concept that is used in medicine to designate a cavity on the surface of an organ. In this case we are talking about the kidneys or spleen.

The hilum is an area where several blood vessels, nerves, and ducts meet. This is a very important place in the body, since this is where the exchange of substances between blood and tissues takes place.

In addition, the gate is also a place for the exit and entry of various liquids and gases. For example, in the kidneys, blood is filtered through the gate, and in the spleen, red blood cells are removed.

However, the gate is not a static area, but constantly changes depending on the state of the body. For example, with inflammation or other diseases, they can become enlarged or narrowed, which can lead to disruption of the organ.

Thus, the gate is an important element in the functioning of the body and requires constant monitoring and treatment if necessary.

A hilum (Hilum, plural Hila) is a cavity on the surface of one of the organs in the body that serves to connect or exit blood vessels, nerves and ducts. These cavities can be either internal or external, depending on where they are located.

For example, the kidneys have two types of gates: external and internal. The external hilum (Hilum externum) is located on the surface of the kidney and forms the entrance to the blood vessels and nerves that transport blood and nutrients to the kidneys. The internal gate (Hilum internum) is located inside the kidney and serves as an outlet for urine and other waste products.

The spleen also has two types of hilum - external and internal, but they are called the hilum splenicum. External gates consist of two parts - large and small. The larger part forms the entrance to the splenic arteries and veins, and the small part forms the exit to the lymphatic vessels. The internal hilum is located inside the spleen and serves as the junction of the splenic artery and vein.

Gates are also found in other organs such as the liver, lungs, intestines and others. They play an important role in transporting blood, nutrients and waste between various organs and systems of the body. However, if the gate is damaged or blocked, it can lead to serious health problems such as loss of blood supply to the organ or infection. Therefore, it is important to monitor the condition of the gate and, if necessary, take preventive measures to protect it.

The hilum (also known as hilum, plural hila) is a cavity on the surface of an organ, commonly called the hilum of function. This area is where blood, nerves, ducts, and other important structures flow through the organ. The functionality of the gate depends on which organ it covers. Each kidney and each unpaired liver has its own gate, but other organs also have gates, although they are called differently. Here are some of the important organs, including their hilum:

1. The kidney contains the renal hilum (hilum renal), which connects the renal artery, renal vein and ureters. 2. The spleen has a pair of smooth bags (or bands) in which the splenic hilum is located. These lymphatic gates hold the lymphatic vessels from the spleen and the splenic artery. 3. The liver has its own hilus (hires du vesicule sanguine), where the two main hepatic veins enter the hepatic vein. There is also an artery and two bile ducts. 4. The pancreas has several gates, the so-called azygos, where the main pancreatic duct is located. 5. Lymph nodes have several lymphatic portals or bags or pockets. They contain lymphatic arteries, lymphatic venous channels, and sometimes the lymphatic blood supply. 6. Spleen and ovaries
