Symmorphosis

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by Jmoore31 (talk | contribs) at 20:17, 21 February 2019 (I have added more on the background as well as symmorphosis with the respiratory system).

Symmorphosis

When the formation of elements are regulated to meet the needs of the requirements of a functional system is the principle of symmorphosis within a physiological system.[1] In biological organisms, symmorphosis is when a quantitative match of design and function within an organism defined within a functional system[2](Weibel, 1991).   Some examples of this in the human body could be how bones are structured to withstand stress, how blood vessels are designed to distribute blood throughout the body without using a lot of energy or even how as a person becomes more physically fit or endures more cardio their body has adjusted to maintain higher functioning demands.[2] Symmorphosis was originally proposed by Ewald Weibel and Charles Taylor in 1981. A common form of testing symmorphosis between species of mammals is to use comparative biology.

I need to add more to the background section of this.

Symmorphosis with the Respiratory System

Recently, symmorphosis has received attention as it has been applied to the oxygen utilization in mammals.The original experimental method for symmorphosis was used to show if the design of the organs were relative to the static demands of the mammalian respiratory system. In particular, this testing would help identify structural elements that differed in order to cary the maximal amount of oxygen throughout the body. [1]
