Describe and list the functions of the cerebrospinal fluid.

homeostatic protection, mechanical protection, circulation

Explanation:

Homeostatic protection: cerebrospinal fluid transports polypeptide hormones and its PH allows for cerebral blood flow as well as pulmonary ventilation

Mechanical protection: cerebrospinal fluid absorbs shock, so that energy from an impact does not directly first affect the spine

Circulation: helps allow for the exchange of nutrients between the blood and adjacent nervous tissue
