nutrients from dead organisms.

and differentiation.
Diaphragm

extends across the bottom of the thoracic cavity. It
separates the thoracic cavity containing the heart

an important function in respiration: as the

cavity increases and air is drawn into the lungs.
Differentiated Cells
These are cells which have become modified and
specialized within an organism.
Digestive System
This system prepares food for cellular utilization.
