Interlobular Veins[edit]

Diagram of the liver showing the interlobular veins.

The interlobular veins are small veins located within the liver. They are part of the hepatic portal system and play a crucial role in the drainage of blood from the liver lobules.

Anatomy[edit]

The interlobular veins are found in the portal triad, which is a distinctive arrangement of vessels and ducts in the liver. Each portal triad consists of a branch of the hepatic artery, a branch of the portal vein, and a bile duct. The interlobular veins are branches of the portal vein and are responsible for collecting blood from the sinusoids of the liver lobules.

Function[edit]

The primary function of the interlobular veins is to drain deoxygenated blood from the liver lobules into the larger hepatic veins, which then carry the blood to the inferior vena cava. This process is essential for the removal of metabolic waste products and the regulation of blood composition.

Clinical Significance[edit]

Disorders affecting the interlobular veins can lead to significant liver pathology. Conditions such as portal hypertension can result in increased pressure within these veins, leading to complications like ascites and varices.

-'''Interlobular veins''' are veins that are located in the renal cortex, a part of the kidney. They receive blood that has been filtered by the kidney and return it to the circulation. The term "interlobular" refers to their location between the renal lobules, which are the functional units of the kidney.

-The term "interlobular" is derived from the Latin words "inter", meaning "between", and "lobulus", meaning "a small lobe". The term "vein" comes from the Latin word "vena", which means "blood vessel".

-Interlobular veins are small veins that are located in the renal cortex. They are surrounded by renal tissue and are located between the renal lobules. Each interlobular vein receives blood from several [[afferent arterioles]], which are small blood vessels that carry blood to the glomeruli for filtration. After filtration, the blood is collected by the [[efferent arterioles]] and then drains into the interlobular veins.

-The main function of the interlobular veins is to collect the filtered blood from the kidney and return it to the circulation. This is an important part of the kidney's role in maintaining the body's fluid and electrolyte balance, as well as removing waste products from the blood.
