. Animal biology. Zoology; Biology. 326 METAZOAN PHYLA (Fig. 216). If these tubules belong to metameres located far forward in the body, the organ is called a pronephros, or head kidney; such tubules open freely into the coelom by a ciliated funnel and take the waste from it (Fig. 217). The vascular organ which passes the excretions from the blood into the coelom is known as a glomus. If the metameres represented are farther back, the organ is called a mesonephros; each Pronephric tubule. Cayify ofmyo- -f-ome Pronephric ducf.
