More and more elements were added and it has grew bigger.
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
Spontaneous creation. The theory that when a large area lacks matter it randomly creates new matter. The new matter created cause chemical reactions forming stars. One of the stars exploded triggering explosive substances making a big bang. Then some atoms formed into a cell. It evolved into a many-celled organism that reproduced and created more organisms. They eventually evolved tissues, organs, and then organ systems. Then some of the organisms evolved the ability to think and they reproduced creating early forms of humans. They eventually evolved into what we are now.or you could call it the big bang theory
The main reason for this is evolution. When we say an organism is evolved, it means that they have more advanced systems - and their pathways are more complex. Even genetically speaking, evolved organisms generally have more types of genes for a particular function. Now, when you talk about cellular metabolic pathways, lower organisms like prokaryotes are only evolved enough to code for the enzymes that are a part of or regulate glycolysis. They do not contain the enzymes, as well as the structures (mitochondria) to conduct higher cellular functions like Krebs cycle or ETC. In comparison, eukaryotes have genes for the same and thus are able to carry out these functions. It all comes down to whether it has a gene to do that particular function.

Certified Clinical Medical Assistant/SpecialistLearn more about exams.....Duties: Perform administrative and certain clinical duties under the direction of a physician. Administrative duties may include scheduling appointments, maintaining medical records, billing, and coding information for insurance purposes. Clinical duties may include taking and recording vital signs and medical histories, preparing patients for examination, drawing blood, and administering medications as directed by physician.
Both are Clinical Data Management Systems (CDMS), developed by different companies. ClinTrial is a product by Phase Forward and Oracle Clinical (OC) is a product by Oracle. Though they have different features, basic functionality is the same Check http://en.wikipedia.org/wiki/Clinical_data_management_system for more details about CDMS Basically CDMS systems are used in case of paper & hybrid (paper and EDC) trials.
EMR (Electronic Medical Records) were introduced to reduce paper and automating clinical and administrative workflows of medical practices electronically to make processes more efficient and effective to achieve high care quality.
They have evolved to be more accurate.
That is a complex question. Both are clinical data management systems used by hundreds of companies. Both products are now owned by Oracle. Clintrial is more modular and has separate tables for each trial where Oracle Clinical is more robust and has consolidated data. Both have numerous interfaces and add-on functionality. They are both Oracle Based and web enabled.
When something is evolved, it is a more advanced form.
A CDSS has been defined as active knowledge systems which use two or more items of patient data to generate case-specific advice. It is an application that analyzes data to help healthcare providers make clinical decisions. A clinical decision support system is an adaptation of the decision support system commonly used to support business management.
Because our bodies have evolved to defend ourselves from these pathogens. We have an "immune system".
The source of the first feudal system is not known. One of the most famous feudal systems was set up in England under the government of William I. He was also known as William the Conqueror, and ruled from December of 1066 to September of 1087.
focusing more on billing and information systems. He had already made CIGNA a part of the Coalition for Affordable Quality Healthcare in an effort to simplify the administrative burden for physicians and their office staffs
Cuneiform was eventually replaced by alphabetic writing systems, such as the Phoenician alphabet, which evolved into the Greek and Latin alphabets. These systems were simpler and more efficient for recording language.
