GCU BIO 210 EXAM 1 QUESTIONS & ANSWERS
How are anatomy and physiology related?
structure determines function
What are the specialties of gross/macroscopic anatomy?
Surface
Regional
Systemic
Development
Clinical
What are the specialties of microscopic anatomy?
Cytology
Histology
What is surface anatomy?
exterior features
What is regional anatomy?
body areas
What is systemic anatomy?
organ systems
What is developmental anatomy?
Observes from egg to maturation
What is cytology?
study of cell structure
What is histology?
study of tissues
What are the specialties of physiology?
Cell
Organ
Systemic
Pathogenic
What is cell physiology?
study of cell function
What is organ physiology?
functions of specific organs
, What is systemic physiology
functions of an organ system
What is pathogenic physiology?
Effects of disease
What are the six levels of structural organization?
chemical, cellular, tissue, organ, organ system, organismal
What is metabolism?
sum of all chemical reactions in the body
What are the two types of metabolic reactions?
anabolism and catabolism
What is anabolism?
building up
An example of anabolism
synthesis of protein from amino acids
What is catabolism?
breaking down
An example of catabolism is
Breakdown of glucose
What is homeostasis?
the ability to maintain a relatively stable internal environment
What is the importance of homeostasis
Keeps the body under control and keeps the right conditions for cells to live. Without it
we would die
What is intrinsic regulation?
autoregulation;
Local, organ system adjusts to environmental change.
example of autoregulation (intrinsic)
when oxygen levels decline in a tissue, the cells release chemicals that dilate local
blood vessels, the dilation increases the rate of blood flow and provides more oxygen to
the region
What is extrinsic regulation?
Responses controlled by nervous and endocrine systems;
Calls on organs for help
Example of Extrinsic Regulation
when you exercise the nervous system issues commands that increase your heart rate
so that the blood will circulate faster
