CH 1 Organization of the Body Flashcards
studies the structure of the body part and their relationships to one another
anatomy
concerns the function of the body in other words how the body parts work and carry out their life-sustaining activities.
physiology
is the study of large body structures visible to the naked eye such as the heart lungs and kidneys
Gross, or macroscopic, anatomy
all the structures (muscles bones blood vessels nerves etc in a particular region of the body such as the abdomen or leg are examined at the same time
regional anatomy
body structure is studied sytem by system
ex: cardiovascular system you would examine the heart and the blood vessels of the entire body
systemic anatomy
another subdividion of gross anatomy. The study of internal structures as they relate to the overlying skin surface
surface anatomy
deals with structures too small to be seen with the naked eye
microscopic anatomy
subdivision of microscopic anatomy include ——- which considers the study of cells in
the body
cytology
the study of tissues
histology
traces the structural changes that occur throughout the life span
developmental anatomy
a subdivision of developmental anatomy, concerns develipmental changes that occur before birth
embryololgy
concerns kidney function and urine production
renal physiology
explains the workings of the nervous system
neurophysiology
examines the operation of the heart and blood vessels
cardiovascular physiology
the key concept that anatomy and physiology are inseperable because funtion always reflects structure
principle of complentarity of structure and function
atoms, tiny building blocks of matter combine to form molecules such as water and proteins
chemical level
molecules in turn associate in specific ways to form oraganelles that the basic components of cells; the smallest unit of living things
cellular level
the simpliest living creatures are single cells but in complex organisims such as hman beings the heirarchy continues on to the
tissue level
epithelial tissue covers the body surface and lines its cavaties. muscle tissue provides movemnet. conective tissue supports and protects body oragans. nervous tissue provides a means of rapid interal communcation by transmitting electrical impulses
each tissue
extremely complex functions become possible
organ level
organs that work together to accomplish a common purpose make up an
organ system level
the highest level of organization is the organism, the living human being
organism level
hair skin nails
integumentary system
bones joint
skeletal system
