Respiratory Histology by Dr R.M
Transcript of Respiratory Histology by Dr R.M
Preface
the respiratory system.
Then we can enjoy solving another
you a
Where the idea of creating Medical E-Books began & will continue i.s.A.
I would be pleased to receive your comments & suggestions on my e-mail
In the name of Allah, most Gracious, most Merciful
phenomena.
A single genius invention has revealed most of these secrets, taking us to the cellular
& sub cellular levels, where we discovered a new world of smart knowledge...
The world of microscopy.
This simple E-Book takes us in a short journey within this world...
For thousands of years, many medical aspects have been a matter of unexplained
50 colored labeled microscopic slides in In this journey, we will display more than
50 MCQ's, provided with an answer guide giving
check or cross mark on pressing the box denoting each choice.
I really dedicate this book to all who helped & encouraged me through out the stages
I dedicate this work to my family, friends & of course to my teachers since the
primary stage till this moment.
I especially dedicate this book & all the coming parts i.s.A to my colleagues on the
of data collection & Book designing.
