EXAM 1 STUDY GUIDE: BIO-201
HUMAN ANATOMY AND
PHYSIOLOGY, 2025/2026 WITH
CORRECT/ACCURATE ANSWERS
What is Physiology?
study of the function
2 Homeostasis Methods of Regulation:
Intrinsic regulation vs Extrinsic regulation
Intrinsic regulation - automatic adjustment of organs to
environment
extrinsic regulation - nervous & endocrine system act to regulate
homeostasis.
what is Anatomy?
study of the body structure
What are the specialties of physiology?
cell physiology - processes within/bt cells
organ physiology - function of specific organs
systemic physiology - function of the organ system
pathological physiology - effects of disease
, What is pH?
concentration of H+ in a solution
What is an example of Neutral pH and what does it mean?
Pure water, a balance of H+ and OH-
Acid pH level is...
lower than 7.0 and have a high H+ concentration
Basic pH level is...
higher than 7.0 and have a high OH- concentration
List the pH levels of blood
7.4
Excessive H+ in body fluid (low pH) is called...
acidosis
Excessive OH- in body fluid (high pH) is called...
alkalosis
Name the buffer that the body uses to restore homeostasis or
neutralize when pH levels are low/high.
bicarbonate
Homeostasis
maintenance of physiologic balance of all components and
functions in the body
(balance of ions)
What are the specialties of anatomy?
