Excretion in Enteropneusts may involve a series of blood tissues called the ______?

Excretion in Enteropneusta, commonly known as acorn worms, involves a series of blood tissues called the glomerulus. Here is some additional information about this process: • The glomerulus is a vascular complex located in the proboscis (the front-most part of the acorn worm's body). • It is a cluster of blood sinuses and peritoneal folds that is thought to have an excretory function. • Waste is filtered from the blood through the glomerulus and excreted through the proboscis pore. • The glomerulus is considered the primary excretory organ in Enteropneusta, which lack a more defined excretory system.
