Anatomy & physiology are inter-dependent
Some believe human anatomy can be understood without thinking about the body’s physiology . Some even go so far as to think physiologic function is separate from the biochemical composition of the body.
That is not correct. It is physiology that gives the body substance as well as permitting its movement within its environment. Physiology shapes the anatomy of the body. When function fails anatomy wastes away.
Studying anatomy and physiology is easy when the big picture is focused upon first. And, the big picture consists of learning the basics of body chemistry.
The Body Constantly Reshapes and Renews
For those of you who are taking anatomy and physiology because your goal is to become a healthcare professional, body chemistry will soon become a focus of your professional life. Body chemistry is physiology. And, physiology constantly remolds a person’s anatomy.
As children grow their physiology and anatomy evolve together into an adult configuration. When adults consistently exercise parts of their anatomy, physiology changes the shape of the performing elements. For example, if you lift weights for exercise your muscles get bigger. If you run for exercise your muscles get thinner. As people age the adult form of their anatomy again changes. Anatomical consequences of aging are driven by adjustments in body chemistry.
Should Chemistry be Take Before A&P
You may be wondering if you should take chemistry first. The answer is, not really. Happily, body chemistry relies on fewer principles than organic chemistry in general. In fact it is difficult to translate chemistry as taught in chemistry class into physiology. This is because body chemistry is restricted to a very narrow temperature range unlike test tube chemistry.
Rather than proceeding through the first few weeks of your anatomy and physiology course trying to figure out body chemistry on your own, you may want to check out my book on this subject – “Physiology: Custom-Designed Chemistry; Getting past the anxiety that physiological chemistry is too hard to learn.” It is a quick read.
