Holism
Idea where properties of a the whole organism cannot be predicted from the properties of its specific parts.

The person to originate the theory of natural selection. HIs books was coined "the book that shook the world"
48
Development
An change in form or function
49
Differentiation
The transformation of cells with no function into cells with specialized functions.
50
Homeostasis
The boys ability to detect change, activate mechanisms to oppose it, and thereby maintain relatively stable conditions.
51

Carefully cutting and separating tissues to reveal their relationship.
52
Psychosomatic Effects
Effects of the subjects state of mind on their psychology.

The ability to sense and react to stimuli
54
Cells
The smallest unit of life which carry out basic life function
55
Organ
A structure composed of two or more tissue types that work together to carry out a specific function

When a large, complex system can be understood by studying the simpler components.
57
Anatomy
The study of human structure
58
Neurophysiology

The first to study cells with a compound microscope and also was the first to observe blood cells and capillaries.
60
Pathophysiology
Mechanisms of disease

Atoms
Smallest unit of matter with unique chemical identity

The shrinking go blood vessels. Forces shivering and the body to gain heat.

Must be consistent with what is already known.
65
Integrating Control Center
A mechanism that processes the information, relates it to other information and makes a decision about what the appropriate response should be.
66
Positive Feedback
