Chapter 1 definitions Flashcards
The study of life
Biology
Also called irritability - organisms respond to changes in their immediate environment
Responsiveness
Organisms making long-term changes as they adjust to their environment
Adaptability
Organisms increase in size through the growth or addition of cells
Growth
The simplest units of life
Cells
Organisms reproduce, creating new generations of the same kind of organisms
Reproduction
Organisms exhibit movement. The movement may be internal (transporting food, blood, or other materials within the body) or external (moving through the environment)
Movement
Organisms rely on complex chemical reactions to provide the energy required for responsiveness, growth, reproduction, and movement. It refers to all the chemical operations in the body
Metabolisms
Also known as Macroscopic anatomy, considers features visible with the unaided eye
Gross Anatomy
The study of general form and superficial markings
Surface Anatomy
The study of all the superficial and internal features in a specific region of the body, such as the head, neck, or trunk.
Regional Anatomy
The study of the structure of major organ systems, which are groups of organs that work together in a coordinated manner
Systemic Anatomy
Concerns structures that we cannot see without magnification
Microscopic Anatomy
Analyzes the internal structure of individual cells
Cytology
Examines tissues
Histology
The study of the functions of living cells
Cell Physiology
The study of the physiology of specific organs
Special Physiology
Considers all aspects of the function of specific organ systems
Systemic Physiology
The study of the effects of diseases on organ or system functions
Pathology
Refers to a stable internal environment
Homeostasis
Refers to the adjustments in physiological systems that preserve homeostasis
Homeostatic Regulation
A cell or organ that is sensitive to a particular environmental change or stimulus
Receptor
Receives and processes information from the receptor
Control Center
A cell or organ that responds to the commands of the control center and whose activity opposes or enhances the stimulus
Effector
