What is the definition of anatomy?
It is the study of the structure of the body and the physical relationship between its constituent parts.
What is the definition of physiology?
It is the study of how the body system work and in which their integrated activities maintain life ad health of the individual.
Definition of Pathology?

Definition of Pathophysiology?
It is the study of how abnormalities affect body function, often causing illness.

How are tissue formed?
Cells with similar function and structures combine to form tissues
How are organs formed?
A number of different type of tissues combine to form an organ which carry out a specific function

What is external environment?
It surrounds the body and is the source of oxygen and nutients for the cells.
Waste product are excreted into the extrenal environment.
What is the internal environment?
