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

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
