Final answer:
The function of canaliculi in osteocytes is to exchange nutrients and waste products with other osteocytes.
Step-by-step explanation:
Osteocytes are mature bone cells that are located in spaces called lacunae within the bone. Canaliculi are small channels that connect the lacunae and allow osteocytes to exchange nutrients and waste products with each other and with the central canal. This system of canaliculi aids in the transport of nutrients to the osteocytes and removal of waste from them.
