Anatomy and Physiology: Module 1 and Module 2 Flashcards
It studies the structure of body parts and their relationships to one another.
ANATOMY
The word “anatomy” comes from a Greek root that means “_____”
TO CUT APART
It is the study of large body structures visible to the naked eye, such as the heart, lungs, kidneys.
GROSS ANATOMY
All structures in particular region of the body. It is the study of the organization of the body by areas.
REGIONAL ANATOMY
Body structures are examined system by system.
SYSTEMIC ANATOMY
It is the study of internal structures as they relate to the overlying skin. It is the study of external features, such as bony projections, which serve as landmarks for locating deeper structures.
SURFACE ANATOMY
It deals with structures too small to be seen by the naked eye (cytology, histology).
MICROSCOPIC ANATOMY
It involves the use of x-rays, ultrasound, magnetic resonance imaging (MRI) and other technologies to create pictures of internal structures.
ANATOMICAL IMAGING
Traces structural changes that occur throughout the life span.
DEVELOPMENTAL ANATOMY
It studies the function of the body, how the body parts work and carry out their life-sustaining activities.
PHYSIOLOGY
It is the study of a specific organism, of human, whereas cellular physiology and systemic physiology are subdivisions that emphasize specific organizational levels.
HUMAN PHYSIOLOGY
It is the state of steady internal conditions maintained by living things.
HOMEOSTASIS
What are the levels of structural organization of the human body?
CHEMICAL LEVEL
CELLULAR LEVEL
TISSUE LEVEL
ORGAN LEVEL
ORGAN SYSTEM LEVEL
ORGANISMAL LEVEL
Atoms bond to form molecules with three-dimensional structures.
CHEMICAL LEVEL
Cells are made up of molecules. A variety of molecules combine to form the fluid and organelles of a body cell.
CELLULAR LEVEL
It is the smallest independently unit of a living organism.
CELL
A human cell typically consists of flexible membranes that enclose cytoplasm, a water-based cellular fluid together with a variety of tiny functioning units called ______?
ORGANELLES
A community of similar cells form a body tissue.
TISSUE LEVEL
It is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function.
TISSUE
Two or more different tissue combine to form an organ.
ORGAN LEVEL
An anatomically distinct structure of the body composed of two or more tissue types.
ORGAN
Two or more organs work closely together to perform the functions of a body systems.
ORGAN SYSTEM LEVEL
A group of organs that work together to perform major functions or meet physiological needs pf the body.
ORGAN SYSTEM
What are the systems of the body?
Integumentary, Skeletal, Muscular, Endocrine, Nervous, Reproductive
Forms the external body covering, and protects deeper tissues from injury. Synthesizes vitamin D, and houses cutaneous (pain, pressure, etc.) receptors, and sweat and oil glands.
INTEGUMENTARY SYSTEM
Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells
ENDOCRINE SYSTEM
Picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in the lymphatic stream. Houses white blood cells (lymphocytes) involved in immunity. The immune response mounts the attack against foreign substances within the body.
LYMPHATIC SYSTEM/IMMUNITY
Overall function is production of offspring. Testes produce sperm and male sex hormone, and male ducts and glands aid in delivery of sperm to the female structures serve as sites for fertilization and development of the fetus. Mammary glands of female breasts produce milk to nourish the newborn.
MALE AND FEMALE REPRODUCTIVE SYSTEM
Allows manipulation of the environment, locomotion, and facial expression. Maintains posture, and produces heat.
MUSCULAR SYSTEM
Eliminates nitrogenous wastes from the body. Regulates water, electrolyte, and acid-base balance of the blood.
URINARY SYSTEM
Breaks down food into absorbable units that enter the blood for distribution to body cells. Indigestible foodstuffs are eliminated as feces.
DIGESTIVE SYSTEM
As the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands.
NERVOUS SYSTEM
Protects and supports body organs, and provides a framework the muscles use to cause movement. Blood cells are formed within bones. Bones store minerals.
SKELETAL SYSTEM
Keeps blood constantly supplied with oxygen and removes carbon dioxide. These exchanges occur through the walls of the air sacs of the lungs.
RESPIRATORY SYSTEM
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood.
CARDIOVASCULAR SYSTEM
Keeps blood constantly supplied with oxygen and removes carbon dioxide. These exchanges occur through the walls of the air sacs of the lungs.
RESPIRATORY SYSTEM
As the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands.
NERVOUS SYSTEM
It is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions.
CATABOLISM
It is the set of metabolic pathways that construct molecules from smaller units, these reactions require energy, known also as an endergonic process.
ANABOLISM
What are the requirements for life or survival needs?
Nutrients, Oxygen, Water, Normal Body Temperature, and Atmospheric Pressure
It is the ability of the body to maintain relatively stable internal conditions even though the outside world changes continuously.
HOMEOSTASIS
An inability of the body to restore a functional, stable internal environment.
HOMEOSTATIC IMBALANCE
Refers to a person standing erect and facing forward, the upper limbs are by the sides, the palms of the hands are directed forward, the lower limbs are together, the soles of the feet are on the ground. Also known as the standard anatomical position.
ANATOMICAL POSITION
It means lying flat on your stomach.
PRONE POSITION
It means lying flat on your back; lying horizontally with the face and torso facing up.
SUPINE POSITION
Vertical plane passing through the center of the body, dividing it into equal right and left halves.
MEDIAN PLANE
Any plane parallel to the median that divides the body into unequal right and left portions.
SAGITTAL PLANE
Vertical plane situated at a right angle to the median plane. It divides the body into anterior and posterior portions.
CORONAL (FRONTAL) PLANE
Lies at right angles to both the median and the coronal planes. It divides the body into upper and lower parts.
HORIZONTAL PLANE
Lies perpendicular to the long axis of a given structure and divides that structure in a “cross-sectional” orientation.
TRANSVERSE PLANE
The front part of the body.
ANTERIOR
The back part of the body.
POSTERIOR
The front part of the hand.
