radiole मीनिंग इन हिंदी

The blood circulation in the periphery, especially the radiole, is especially unusual.
The single vessels in each radiole of the branchial crown, and the vessels of opercula, are all branches of the two branchial vessels.
Instead of venous and arterial blood flowing through efferent vessels within the radiole, there is a single branchial sinus through which blood flows in both directions, in a tidal fashion.
The dorsal or upper side of each radiole has a ciliated longitudinal radiolar food groove running down its center, extending along its longitudinal axis from the tip to the center of the crown.
