Nutrition
Definition:
(n.) In the broadest sense, a process or series of processes by which the living organism as a whole (or its component parts or organs) is maintained in its normal condition of life and growth.
(n.) In a more limited sense, the process by which the living tissues take up, from the blood, matters necessary either for their repair or for the performance of their healthy functions.
(n.) That which nourishes; nutriment.
