HUMAN BODY Flashcards
Is the study of the larger structures of the body, those visible without the aid of magnification.
Gross anatomy
The study of structures that can be observed only with the use of a microscope or other magnification devices.
Microscopic anatomy
The study of the interrelationships of all of the structures in a specific body region, such as the abdomen.
Regional anatomy
The study of the structures that make up a discrete body system
Systemic anatomy
The scientific study of the chemistry and physics of the structures of the body
Physiology
The state of steady internal conditions maintained by living things.
Homeostasis
The smallest independently functioning unit of a living organism.
Cell
Water-based cellular fluid together with a variety of tiny functioning units.
Organelles
A group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function.
Tissue
An anatomically distinct structure of the body composed of two or more tissue types.
Organ
A group of organs that work together to perform major functions or meet physiological needs of the body.
Organ system
A living being that has a cellular structure and that can independently perform all physiologic functions necessary for life.
Organism
A human body consists of trillions of cells organized in a way that maintains distinct internal compartments.
ORGANIZATION
The first law of thermodynamics holds that energy can neither be created nor destroyed—it can only change form.
METABOLISM
The process whereby smaller, simpler molecules are combined into larger, more complex substances.
Anabolism (Synthesis of Larger molecules)
