Today's lab uses human subjects. The classic animal lab is the "frog nerve-muscle" preparation,
one of the labs at University of Missouri - Columbia. Electrodes in the gastrocnemius muscle

Mostly, the pancreas is an exocrine gland involved in digestion.
Additionally, there is an endocrine portion, the islets of Langerhahns.
Alpha cells secrete glucagon.
Beta cells secrete insulin.

In this laboratory, traditional (old) and new equipment will be set up to demonstrate:
(1) principles of recording
(2) limitations solved by more modern equipment

Two objectives of this to lab course are to supplement and reinforce the coverage of the
associated lecture. The other is to extend this coverage. Sensory physiology, optics, the eye
and vision are optimal subjects for laboratory exercises, and we have as
Ventilation or breathing is responsible for providing a continual supply of oxygen and the
removal of carbon dioxide from the body. From the simple observation of a normal subject it is
evident that inspiration and expiratio

Kidney function is divided into six major areas:
Regulation of extracellular fluid volume. When ECF decreases, blood pressure

What you need
A prerequisite or corequisite for this lab (BIOL 347) is the lecture (BIOL 454, or equivalent), and
the required text is Silverthorn, Human Physiology (Fourth edition), San Francisco, Pearson Benjamin Cummings, 2007
Although lectures in BIOL454 on systems (such as circulation) are so advanced that digestion
does not fit into that course, Dr. Bode's research on liver overlaps more with digestion than any
of his topics.
At Mizzou, they did a lab on sm
