A system is a set of interacting or interdependent component parts forming a complex/intricate whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.
The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term is used to describe the set of rules that govern structure and/or behavior.
The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole compounded of several parts or members, system", literary "composition".
According to Marshall McLuhan,
"System" means "something to look at". You must have a very high visual gradient to have systematization. In philosophy, before Descartes, there was no "system". Plato had no "system". Aristotle had no "system".
In the 19th century the French physicist Nicolas Léonard Sadi Carnot, who studied thermodynamics, pioneered the development of the concept of a "system" in the natural sciences. In 1824 he studied the system which he called the working substance (typically a body of water vapor) in steam engines, in regards to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a boiler, a cold reservoir (a stream of cold water), or a piston (to which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term "working body" when referring to the system.
A biological system is a complex network of biologically relevant entities. As biological organization spans several scales, examples of biological systems are populations of organisms, or on the organ- and tissue scale in mammals and other animals, the circulatory system, the respiratory system, the nervous system, etc.
On the micro to the nanoscopic scale, examples of biological systems are cells, organelles, macromolecular complexes and regulatory pathways.
A biological system is not to be confused with a living system, which is commonly referred to as life. For further information see e.g. definition of life or synthetic biology.
These specific systems are widely studied in Human anatomy. "Human" systems are also present in many other animals.

This is a rap I created with my science students. "So Many Sytems" features the outrageous organisms from CrappyTeacher's hit song "Cells Cells" with new guest artist Planarian Pete featured on the bass line. Feel free to comment, like, and share!

Video featuring, from IBM: Mike Wing, Irving Wladawsky-Berger and Julia Grace. If you look at our planet from space, what you see is something like a neural network with the cities as its nodes, and that is as good an image of the planet as a complex system of systems as one could hope for. With the emergence of the internet in the mid-90's, the world became one global commons. In the past, we could understand that there was some mysterious unity to the various dimensions of life but we couldn't understand its dynamics, we couldn't observe and measure their interactions. We basically operated like the drunk who looks under the streetlight for his keys because that's where he can see. Animation by Lisa Kwon http://www.ibm.com/think http://asmarterplanet.com
002 - Environmental Systems Water: https://youtu.be/iOOvX0jmhJ4 pH: https://youtu.be/rIvEvwViJGk Biological Molecules: https://youtu.be/PYH63o10iTE In this video Paul Andersen explains how matter and energy are conserved within the Earth's system. Matter is a closed system and Energy is open to the surroundings. In natural systems steady state is maintained through feedback loops but can be be affected by human society.

This is the updated Amoeba Sisters human organ systems video, which provides a brief introduction to each of the 11 human organ systems including the circulatory, digestive, endocrine, excretory, integumentary, lymphatic/immune, muscular, nervous, reproductive, respiratory, and skeletal systems. The Amoeba Sisters Channel features two sisters on a mission to demystify science with humor and relevance by creating free science videos. Since one of us is a biology teacher, our videos tend to have a life science and biology focus. You can find more info about our videos, GIFs, comics, and handouts on our website on AmoebaSisters.com. We always welcome comments, but we do have our comments on "approval" only.

Igor Nikolic graduated in 2009 on his dissertation: co-evolutionary process for modelling large scale socio-technical systems evolution. He received his MSc as a chemical-- and bioprocess engineer at the Delft University of Technology. He spent several years as an environmental researcher and consultant at University of Leiden where he worked on life cycle analysis and industrial ecology. In his research he specializes in applying complex adaptive systems theory and agent based modeling. On TEDxRotterdam Igor Nikolic left the audience in awe with his stunning presentation and visualizations, mapping complex systems. About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share...
This video provides a basic introduction to the science of complex systems, focusing on patterns in nature. (For more information on agent-based modeling, visit imaginationtoolbox.org).
There's a war, there's a clash of sorts
Dead ahead
It's foreign but it's real
Knock, knock, knock
There it sits taxing every move
Your world son
So either get your gun or clean theirs
With the neck of your ego on the chopping block
Sugar memories bring you back to a time when
Your loudest care was a high chair
Not a number or a name for you to make
This is it 'cause luck moved out last week
No more camp
So shine your saber well
Before you kill a panzer tank with it
Like you told everyone you would
Good bye
Bend and spread or be dead with no history
So live for the luxuries
