Hole's Human Anatomy and Physiology
Chapter 1
anatomy - ANS examines the form and organization of body parts
physiology - ANS considers functions of body parts
Andreas Veralius - ANS founder of modern anatomy
- 16th century
- "On the structure of the Human Body"
levels of organization - ANS - subatomic particles
- atom
- molecule
- macromolecule
- organelle
- cell
- tissue
- organ
- organ system
- organism
atom - ANS smallest component of a chemical element
molecule - ANS more than one atom coming together
macromolecules - ANS more than one molecule coming together
organelles - ANS complex structures inside of cells
cell - ANS basic unit of structure and function
tissue - ANS specialized cell layers or masses that have a specific function
organs - ANS groups of different tissues coming together for a specific function
, organ systems - ANS groups of organs that function closely together
organism - ANS interacting organ systems
characteristics of life - ANS movement, responsiveness, growth, reproduction,
respiration, digestion, absorption, circulation, assimilation, excretion
metabolism - ANS physiological event that allows organisms to obtain, release, and
use energy
requirements of organisms to maintain life - ANS water, food, oxygen, heat and
presssure
homeostasis - ANS body's ability to keep its internal conditions stable
homeostasis mechanism - ANS receptor, control center, effectors
negative feedback loop - ANS continual mechanism that works to return conditions in
the body to normal (i.e. blood pressure, maintaining body temp)
positive feedback loop - ANS short lived mechanism where a change in the body is not
reversed but intensified until task is complete (i.e. child birth, blood clotting)
axial portion - ANS head, neck and trunk
appendicular portion - ANS upper and lower limbs
cranial cavity - ANS brain
vertebral canal - ANS spinal cord, surrounded by sections of the backbone
thoracic cavity - ANS lungs and mediastinum (containing the heart, esophagus, trachea
and thymus)
mediastinum - ANS region between the lungs
abdominopelvic cavity - ANS containing the abdominal and pelvic cavities
abdominal cavity - ANS body cavity which contains the stomach, liver, spleen,
gallbladder, kidneys, and the large and small intestines
