In biology, an organ system is a group of organs that work together to perform one or more functions. Tsang also heads bioinformatics at the trans-NIH Center for Human Immunology (CHI), using similar integrative genomics approaches to study the human immune system, such as immune reactions to the flu vaccine in patients. And they have a top-down approach that uses inferences from perturbation analyses to probe the large-scale structure of the interactions not only at the cellular level, but also at the tissue and even the organism level. This conceptual lack of clarity complicates the scientific and public discourse on chances, risks and limits of Systems Medicine and may lead to unfounded hopes. It uses and extends concepts from thermodynamics and develops other macroscopic descriptions of complex systems. Systems biology, the study of the interactions and behaviour of the components of biological entities, including molecules, cells, organs, and organisms. These data sets ultimately feed into Meier-Schellersheim’s software to produce quantitative models. Fraser said immune-system signaling networks can be unraveled by using proper systematic approaches to interpret complex data sets. Through these actions, the endocrine system regulates nearly every metabolic activity of the body to produce an integrated response. The branch of biology that uses computational techniques to analyze and model how the components of a biological system such as a cell or organism interact with each other to produce the characteristics and behavior of that system. adj., adj homeostat´ic.

The nervous system in a human is made of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body. These includeperception, cognition, signalling, and language use. Sophisticated computational models and simulations represent integral parts of systems biology. The complement system is made up of a number (mostly 30) of distinct serum (blood plasma) and membrane proteins which mostly assist the humoral branch of the immune system. “It’s even worse than the elephant,” that infamous elephant that stymies the attempts of blind men to describe it because each feels just one part. The new NIAID lab reflects an intellectual journey that Germain and some of his NIH colleagues embarked upon as the Human Genome Project was nearing completion. The human respiratory system is adapted to allow air to pass in and out of the body, and for efficient gas exchange to happen. This early into the chase, the lab has not yet published results on these pursuits, although a paper is pending on the lab’s work with CHI and the flu. “So, what am I doing in all of this aside from raising money and pontificating?” Germain joked. The human body is made up of multiple systems that work together to form life. Germain helped change the NIH tenure process, too, to be sure that team science, and not necessarily a steady stream of published papers, is recognized and rewarded.
