Chapter 1 Flashcards
What are the necessary life functions
Maintaining boundaries Movement Responsiveness Metabolism Differentiation Reproduction Growth
Maintaining boundaries function
Allows an organism to maintain separate internal and external environments or separate internal chemical environments
Movement function
Allow the organism to travel through the environment and allows transport of molecules within the organism
Responsiveness function
The ability to detect changes in the internal or external environment and respond to them
Metabolism function
Includes all chemical reactions that occur in the body
Reproduction function
The process of producing more cells or organisms
Growth function
An increase in size in body parts or the whole organism
Gross anatomy
The study of structures large enough to be seen with the naked eye
Regional anatomy
The study of all body structures in a given region
Systemic anatomy
The study of all body structures in a body system
Surface anatomy
The study of internal body structures as they relate to the overlying skin
Microscopic anatomy
The study of structures that are too small to be seen with the naked eye
Cytology
The study of individual cells
histology
The study of tissues
Development anatomy
The study of the change in body structures over the course of a lifetime
Pathological anatomy
The study of structural changes associated with disease
Radiographic anatomy
The study of internal structures using specialized visualization techniques
Molecular biology
The study of biological molecules
Level of Structural organization
Atoms, molecules,smooth muscle cells, cellular level, tissue level, organ level, organ system, organismal level.
Homeostasis
The ability of the body to maintain a relatively constant internal environment regardless of environmental changes
Negative feedback mechanisms
Causes the variable to change in the way that opposes the initial change. to prevent sudden, severe changes in the body
Ex: regulation of blood , glucose levels
positive feedback
Causes the variable to change in the same direction as the original change
Ex: regulation of blood clotting, uterine contractions during labor
Components of homeostasis
Variable, receptor, control center, and effector
