Introduction Flashcards
study of structure & function of the human body
Human Anatomy & Physiology
is the scientific discipline that investigates the structure of the body.
Anatomy
to dissect, or cut part and separate, the parts of the body to study
Anatomy
2 basic approaches to study anatomy
Systemic and Regional Anatomy
study of the body by systems, such as nervous
Systemic Anatomy
study of the organization of the body by areas such as head
Regional Anatomy
2 general ways to examine the internal structures of a living person
Surface anatomy & Anatomical imaging
scientific discipline that deals with the processes or functions of living things.
Physiology
Major goals of physiology
- to understand & predict the body’s response to stimuli
- to understand how the body maintains conditions within a narrow range of values in the presence of continually changing internal & external environment
study of a specific organism, the human
Human Physiology
Subdivisions that emphasize specific organizational levels
Cellular and Systemic Physiology
6 Structural Levels
- Chemical Level
- Cell
- Tissue
- Organ
- Organ System
- Organism
level of organization involves how atoms, such as hydrogen & carbon, interact & combine into molecules
Chemical
are the basic structural & functional units of organism, such as plants & animals
Cells
are the small structures that makes up some cells
Organelles
a molecule cells use for a source of energy
adenosine triphosphate
is a group of similar cells & the materials surrounding them
Tissue
4 primary types of tissue
epithelial, connective, muscle & nervous
is composed of two or more tissue types that together perform one or more common functions
Organ
is a group of organs classified as a unit because of a common function or set of functions
Organ System
is any living thing considered as a whole, whether composed of one cell, such as bacterium, or of trillion of cells, such as human
organism
most important common feature of all organism
life
refers to the specific intterrelationships among the parts of an organism and how those parts interact to perform specific functions
Organization
ability to use energy to perform vital functions, such as growth, movement
Metabolism
