BIO 221

The scientific discipline that investigates the body's structure and examines the relationship between the structure of a body part and how it functions.

Studies the structural changes that occur between conception and adulthood.

Changes from conception to the end of the eighth week of development.

Examines the structural features of the cell.

Examines tissues, which are composed of cells and the materials surrounding them.

The study of structures that can be examined without the aid of a microscope, can be approached from either a systematic or regional perspective.

Body is studied system by system- a group of structures that have one or more common functions.

Body is studied area by area.

The study of the external form of the body and its relation to deeper structures.

Use of radiographs (x-rays), ultrasound, magnetic resonance imaging (MRI), and other technologies to create pictures of internal structures.

Physical characteristics that differ from the normal patterns.

The scientific investigations of the processes or function of living things-- to understand and predict the body's response to stimuli to understand how the body maintains conditions within a narrow range of values in a constantly changing environment.

Examines the processes occurring in cells.

Considers the functions of organ systems.

Focuses on the nervous system.

Heart and blood vessels.

True-- A particular function can involve portions of a system in more than one region.

The medical science dealing with all aspects of disease, with the emphasis on the cause and development of abnormal conditions, as well as the structural and functional changes resulting from the disease.

Focuses on the changes in function and structure caused by exercise.

• -Organ System
• -Whole Organism

Involves interactions between atoms.

• Cells are the basic structural and functional units. 
• Organelles are the small structures that make up cells.

A tissue is composed of a group of similar cells and the materials surrounding them. The characteristics of the cell and surrounding materials determines the functions of the tissue.

• -Epithelial
• -Connective
• -Muscle
• -Nercous

An organ is composed of two or more tissue types that perform one or more common functions.

An organ system is a group of organs that together perform a common function or set of functions and are therefore viewed as a unit.

An organism is any living thing considered as a whole- whether composed of one cell or a trillion cells.

The specific interrelationships among the parts of an organism and how those parts interact to perform specific functions.

All the chemical reactions taking place in an organism. Essential for responsiveness, growth, development, and reproduction.

An organism's ability to sense changes in its external or internal environment and adjust to those changes.

Refers to an increase in the size or number of cells, which produces an overall enlargement of all or parts of an organism.

Includes the changes an organism undergoes through time, beginning with fertilization and ending at death.

Change in cell structure and function from generalized to specialized.

Change in the shape of of tissues, organs, and the entire organism.

The formation of new cells or new organisms. Without reproduction of cells, growth and development are not possible. Without reproduction of organisms, species become extinct.
