Unit 1: Chapters 1-3
The Human Body: An Orientation
3 Essential Concepts
The complementarity of structure and function
The hierarchy of structural organization
Homeostasis-
A state of body equilibrium or stable internal environment of the body
Ability to maintain relatively stable internal conditions even the outside world changes continuously
2 Complementary Branches of Science
Anatomy
Studies the structure of body parts and their relationships to one another
Physiology
Concerns the function of the body, how the body parts work and carry out their life-sustaining activities
Study of the function of living organisms
Explainable only in terms of the underlying anatomy
Reference man
155 lb. (70 kg)
Reference woman
125 lb. (57kg)
Chemical level
SIMPLEST level of heirarchy
Here: Atoms combine to form molecules such as water and proteins
Molecules > Organelles
Cells
SMALLEST units of living things
Cellular level
Individual cells vary in size and shape
Reflects their unique functions in the body
Histology
Branch of anatomy dealing w/ the microscopic structures of tissues
Form (anatomy) determines function (physiology)
Gross (macroscopic) Anatomy
The study of large body structures visible to the naked eye
(ex) heart, lungs, kidneys
Gross Anatomy described in 5 different ways
Surface Anatomy-
study of internal structures as they relate to overlying skin surface
Microscopic Anatomy-
deals w/ structures not able to be seen by the naked eye
Systemic Anatomy-
body structure studied system by system
Developmental Anatomy-
traces structural changes that occur throughout the lifespan
Regional Anatomy-
muscles, bones, blood vessels, nerves
Cytology
considers the cells of the body
Chemistry Comes Alive
