Trabecular arteries

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".

Etymology

The term "trabecular" is derived from the Latin word "trabecula", which means "small beam". This is in reference to the beam-like appearance of the trabecular arteries in the spleen.

Structure and Function

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.
