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)
The process by which larger more complex substances are broken down into smaller simpler molecules.
Catabolism (Breakdown of larger molecules)
The ability of an organism to adjust to changes in its internal and external environments.
RESPONSIVENESS
Includes not only actions at the joints of the body but also the motion of individual organs and even individual cells.
MOVEMENT
Houses the brain
Cranial Cavity
Encloses the spinal cord.
Spinal Cavity
The more superior subdivision of the anterior cavity
Thoracic Cavity
The largest cavity in the body.
Abdominopelvic Cavity
The thin membranes that cover the walls and organs in the thoracic and abdominopelvic cavities.
Serous Membrane
