Digestion breaking down ingested material to usable molecules, absorbed by the blood and distributed to all other cells. Metabolism collection of biochemical pathways at the cellular level. Excretion removal of wastes produced during metabolism. Cells, body parts, and whole organisms can grow, regulated by a complex web of chemical interactions. Dorsal cavity protects the nervous system and has two subdivisions, cranial and vertebral. Cranial cavity encases brain and vertebral cavity encases the spinal cord.
