Anatomy and Physiology Overview Flashcards
Abdominal Cavity
The portion of the abdominopelvic cavity that encompasses the area between the diaphragm and bony pelvis
Abdominopelvic Cavity
A ventral body cavity located inferior to the diaphragm and encompasses the area of the abdomen and bony pelvis
The Cell
Smallest unit that can carry out the functions of life
Metabolism
The sum of the body’s chemical reactions
Anabolic Reactions (Anabolism)
Smaller chemicals are combined to form larger ones
Catabolic Reactions (Catabolism)
Larger chemicals are broken down into smaller ones
Growth
The increase in size of an individual cell or in the number of cells; occurs when anabolic reactions outweigh catabolic reactions
Excretion
The process by which waste products are removed from the body
Responsiveness(Irritability)
The property of living organisms by which they sense and react to changes in their environment
Reproduction
The production of new cells within an organism or production of an offspring
Chemical
A substance with a unique molecular composition that is used in or produced y chemical processes

Tissue
A group of structurally and functionally related cells and their extracellular matrix
Organ
Two or tissues combined to produce a structure that has a recognizable shape and that performs a specialized task
Organ System
two or more organs that work together to carry out a broad function in the body
Systemic Anatomy
The study of the human body taken from the perspective of individual organ systems
Regional Anatomy
The study of the human body taken from the perspective of specific body regions
Surface Anatomy
The study of the surface markings of the human body
Gross Anatomy

Microscopic Anatomy
The study of structures of the human boy that require the use of a microscope for observation
Histology
The study of tissues
Cytology
The study of cells
