Trabecular Arteries

The trabecular arteries are a series of small arteries that are found within the spleen. They play a crucial role in the vascular system of the spleen, facilitating the flow of blood through this organ.

Structure

The trabecular arteries originate from the splenic artery, which is a major branch of the celiac trunk. As the splenic artery enters the spleen, it branches into several smaller arteries that run along the trabeculae of the spleen, hence the name "trabecular arteries". These arteries are encased in the connective tissue of the trabeculae, which provide structural support to the spleen.

Function

The primary function of the trabecular arteries is to supply blood to the white pulp and red pulp of the spleen. As the trabecular arteries penetrate deeper into the spleen, they branch into smaller arterioles and capillaries that deliver oxygenated blood to the splenic tissue. This blood supply is essential for the spleen's role in filtering blood, recycling iron, and mounting immune responses.

Clinical Significance

Damage or obstruction of the trabecular arteries can lead to splenic infarction, a condition where parts of the spleen become necrotic due to lack of blood supply. This can occur due to thrombosis, embolism, or trauma. Symptoms of splenic infarction may include abdominal pain, fever, and an elevated white blood cell count.

-'''Trabecular arteries''' are small blood vessels that are part of the [[circulatory system]]. They are found within the [[spleen]], where they play a crucial role in the organ's function. The term "trabecular" is derived from the Latin word "trabecula", which means "small beam".

-Trabecular arteries are part of the [[spleen]]'s vascular system. They branch off from the [[splenic artery]], which is the blood vessel that supplies the spleen with blood. The trabecular arteries then branch into smaller vessels called [[arterioles]], which further divide into [[capillaries]]. These capillaries are where the exchange of oxygen, nutrients, and waste products occurs.
-The spleen plays a crucial role in the body's immune response, and the trabecular arteries contribute to this function by delivering blood to the spleen. This blood contains white blood cells, which are essential for fighting off infections.
