The human body is a complex and complicated machine. It has taken scientists, doctors,
and researchers many years to understand the basics of the human body. Even now, when
there are many sophisticated ways to learn about the mysteries of the human body, doctors
do not know everything about the wonders of this machinery. There are many systems in the
human body that work together to keep the life going. Human beings are remarkable
creatures who differ from the other animals firstly because of their sophisticated nervous
system. They have memory, intelligence, and emotional stability to function as productive
members of a society. Then there are other body systems like the circulatory system, the
respiratory system, the excretory system, the reproductive system, the skeletal system, the
muscular system, and the immune system that helps the body to function. Of all the marvels
of this body machine, the most basic and recognizable system is the digestive system
(Nuland, 1998).
