Human Organism Flashcards
are physical characteristics that DIFFER
from the normal pattern.
Anatomical Anomalies
is the scientific investigation of the processes or
FUNCTIONS of living things.
Physiology
examines the processes occurring in cells,
Cell Physiology
considers the functions of ORGAN SYSTEM
Systemic Physiology
focuses on the nervous system,
Neurophysiology
deals with the heart and blood vessels.
cardiovascular physiology
is the medical science
dealing with all aspects of disease, with an emphasis on the cause and development of abnormal conditions, as well as the structural and functional changes resulting from disease.
Pathology
is the scientific discipline that investigates the body’s
structure—for example, the shape and size of bones.
*To cut apart, dissect, separate
Anatomy
involves interactions between ATOMS, which are tiny building blocks of matter.
Chemical Level
CELLS are the basic structural and functional units
of plants and animals.
Cell Level
A TISSUE is composed of a group of similar cells
and the materials surrounding them.
Tissue Level
An ORGAN is composed of two or more tissue types
that perform one or more common functions.
Organ Level
An ORGAN SYSTEM is a group of organs
that together perform a common function or set of functions and are therefore viewed as a unit.
Organ System Level
An ORGANSIM is any living thing considered
as a whole—whether composed of one cell, such as a bacterium, or of trillions of cells, such as a human.
Organism Level
A characteristic of life that refers to the specific INTERRELATIONSHIPS among the parts of an organism and how those parts interact to perform specific functions.
Organization
A characteristic of life that refers to all of the CHEMICAL REACTIONS taking place in an organism.
Metabolism
A characteristic of life that is an organism’s ability to SENSE CHANGES in its external or internal
environment and adjust to those changes.
Responsiveness
A characteristic if life that refers to an INCREASE in the SIZE OR NUMBER OF CELLS, which produces an overall enlargement of all or part of an
organism.
Growth
includes the changes an organism undergoes
through time, beginning with fertilization and ending at death.
Development
A part of development that is change in CELL STRUCTURE and function from generalized to specialized
Differentiation
A lart of development that is change
in the SHAPE OF TISSUES, ORGANS, AND THE ENTIRE ORGANISM.
Morphogenesis
A characteristic of life where the FORMATION OF NEW CELLS or new organisms.
*Whithout this growth and development are not possible
*Without this organisms and species become extinct
Reproduction
Provides protection, regulates temperature,
prevents water loss, and helps produce
vitamin D. Consists of skin, hair, nails, and
sweat glands.
Integumentary System
Provides protection and support, allows
body movements, produces blood cells, and
stores minerals and fat. Consists of bones,
associated cartilages, ligaments, and joints.
Skeletal System
Produces body movements, maintains
posture, and produces body heat. Consists of
muscles attached to the skeleton by tendons.
Muscular System
Removes foreign substances from the blood
and lymph, combats disease, maintains
tissue fluid balance, and absorbs fats from
the digestive tract.
- Consists of the lymphatic
vessels, lymph nodes, and other lymphatic
organs.
Lymphatic System
Exchanges oxygen and carbon dioxide
between the blood and air and regulates
blood pH.
Respiratory System
Performs the mechanical and chemical
processes of digestion, absorption of
nutrients, and elimination of wastes.
Digestive System
A major regulatory system that detects
sensations and controls movements,
physiological processes, and intellectual
functions.
*Regulates the other systems
- Consists of the brain, spinal cord,
nerves, and sensory receptors.
Nervous System
A major regulatory system that influences
metabolism, growth, reproduction, and many
other functions.
- Consists of glands, such as
the pituitary, that secrete hormones.
Endocrine System
Transports nutrients, waste products, gases,
and hormones throughout the body; plays
a role in the immune response and the
regulation of body temperature.
- Consists of the heart, blood vessels, and blood.
Cardiovascular system
