During January and February the Osher Lifelong Learning Institute
at George Mason University in Virginia is offering its members a chance
to study The Wisdom of the Body. Walter B. Cannon, pioneering American
experimental physiologist, described the many processes involved in this
internal equilibrium of the body as “homeostasis” or the “wisdom
of the body.” Over four weeks, members will study the following
topics with faculty from the University:
Circulation – All areas of the body need
a dependable supply of blood. How do the heart and blood vessels operate
to supply every organ of the body with varying amounts of blood containing
the oxygen, nutrients and other supplies they need?
Digestion – This system processes what
we eat and drink with only occasional protests. What roles do hormones
and nerves play in digestion? What is the role of microbes in the digestive
system?
Immunity – The immune system consists of
organs and cells throughout the body. How do they communicate with each
other? How do vaccinations work?
Respiration – Breathing is normally an
automatic activity, which is primarily adjusted to the needs of the body
to acquire oxygen and get rid of carbon dioxide. How does breathing increase
when you exercise? What happens when you get “out of breath?
