This chapter is about the digestive system, which
processes food so that nutrients can be absorbed and utilized by the cells.
It names the organs of the digestive system and describes their locations and
functions (objectives 1 and 2). The structure, movement, and digestive mechanisms
of the alimentary canal are explained (objectives 3, 4, 7, and 8). The function
and regulation of the secretions of the digestive organs are introduced (objectives
5 and 6). This chapter also tells how nutrients are absorbed from the alimentary
canal (objective 9).
Studying the digestive system will help you to
understand how fuel is made available for metabolism.
