PREFACE

Praise be to Allah, God Almighty for His mercy and gift, so that the author
can finish the textbook. Do not forget to also say prayers and greetings may
always be poured out to the Great Prophet Muhammad SAW, because thanks to
him, we are able to get out of the darkness to a brighter path.

The author also expresses his gratitude to the various parties who have helped so
that this book is completed very well, namely:

1. Mr. Mochammad Iqbal, S.Pd., M.Pd., MCE., CIQnR., CIQaR as a lecturer
who teaches this course who provides a lot of new knowledge in the
development of teaching materials.
2. Mrs. Dr. Sulifah Aprilya H., S.Pd., M.Pd., MCE., CIQnR as the lecturer
who teaches this course who provides a lot of knowledge and theory in the
development of teaching materials
3. The other party who cannot be mentioned one-on-one.

Meanwhile, our textbook entitled 'Digestive System: Digital Book for Class XI'
has been completed as much as possible so that it becomes a benefit for students
who need information and knowledge about the digestive system material.

In this book, there are several materials including food substances needed by the
body, the structure and function of the human digestive system and the structure
and function of the ruminant digestive system. The material of disorders of the
digestive system is also discussed in this book. This book is equipped with several
exciting features such as pictures, learning videos, fun facts, and quotes to
increase students' interest in learning. In addition, this book is also equipped with
consulting services to help students when experiencing difficulties.

We realize that there are still many flaws and fallacies that are certainly far from
perfect about this book. Therefore, we ask that readers give criticism and
suggestions for this textbook work so that we can continue to improve the quality
of the book.

Thus we made this textbook, with the hope that readers can understand
information and also get insight into the digestive system and can be useful for
society in a broad sense. Thanks.
