INTRODUCTION OF HUMAN BODY
Man is the most intelligent and technologically advance living thing on earth. We have known about our gross body for centuries. Now, in this lesson we will understand how it looks from inside and how it performs its functions. The basic knowledge of structure, size, shape, location and functioning of various organs of the human body is provided by two important subjects-Human Anatomy and Physiology which one must study first to understand our body.
After reading this lesson, you will be able to: • Get the knowledge of structure and function of a healthy human body. • Understand the meaning of Anatomy and Physiology. • Know the important systems of human body. • Explain the functions and contribution of each system.
1.3 Anatomy and Physiology
Now, let us find out what does ‘Anatomy’ and ‘Physiology’ mean. Anatomy is the science which deals with the study of normal structure, shape, size and location of various parts of the body. When the study relates to human body it is called human anatomy. For example, when we look at our body we can easily see that it has one face, two hands, two legs etc. and there is skin that completely covers the body. When we open or see inside our body, what do you observe? We can see that internally it is composed of various organs, blood, muscles, bones etc. In this way, in anatomy we can study various structures and composition of our body. Physiology is the study of normal functions of various organs of the body i.e. how each and every part of the body and body as a whole, perform its function?
