Respiratory System.
Physiology of Systems Marianne Connelly Respiratory System The primary function of the Respiratory System is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen. Respiration is achieved through the mouth, nose, trachea, lungs and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes the larynx and the trachea which is a tube that enters the chest. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to the sacs called the alveoli. These are air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. The waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale. The diaphragm's job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles across that
Organisational Structure
ASDA is a hierarchical structure because it has a lot of layers and also a lot of people reporting into more than one person before that information get to the boss. What is a Hierarchical structure? A hierarchical structure has many levels. Each level is controlled by one person. A hierarchical company tends to be a very big company just like ASDA is. In a hierarchical instructions are generally passed down from one person to another until it gets to the bottom of the hierarchical structure. If there was a problem in a hierarchical structure it would move up through the structure again from one person to another until it gets to where it is supported to be. Strengths of a Hierarchical structure In a hierarchical structure there is a close control of workers. Workers in ASDA will know exactly what they have to do so they don't wait around until they are told what they have to do. There is a small span of control. A span of control is when an amount of people report to one person. Also there is a better chance for promotion. Weaknesses of a Hierarchical structure In a hierarchical structure information is slow moving. There may be poor communication between departments. Also workers may not feel involved in the business and they may not feel motivated to work. The types of communication used in a Hierarchical structure The type of communication used is hierarchical will

UNIT 1 - INFORMATION SYSTEMS Assignment 1 Table of Contents Task 1 2 Characteristics of Business Information Relevant to Amazon 2 Task 2 3 Sources of Information needed by Amazon 3 Task 3 4 Business Information used by Amazon 4 Task 4 5 Task 5 6 Task 6 7 Bibliography 9 TASK 1 Characteristics of Business Information Relevant to Amazon CHARACTERISTIC EXPLANATION RELEVANCE TO AMAZON Valid Information that is unbiased, representative and verifiable Any information that Amazon collects needs to be valid otherwise the customers will receive inaccurate information and this is unacceptable. Reliable Information that is trusted, true and dependable. If the information is not reliable then Amazons customers will not be able to depend on it. Timely Information should be available when it is needed for decision making, appropriately (well) timed. Any information needed for projects or customers needs to be recovered as soon as possible or for a deadline otherwise it is useless. Fit for Purpose Information provided for the purpose it is now being used for; the effectiveness of the information. All information the Amazon collects must be fit for purpose otherwise it is unusable. Accessible Information that is easy to get hold of, and if necessary must be able to do calculations with the data. Any information that Amazon uses must be easily accessible
The Role of ICT.
The Role of ICT : Two types of IT system for which failure would be catastrophic would be, for example, an IT system at a power station. If a power station IT system went down this could cause power cuts in certain areas monitored by the system and all kinds of disruption. Another example could be in industry where IT systems are used to monitor certain stages of production. If they failed this would be catastrophic for the organisation, as it would waste time and money. 2: A social impact of introducing computerised information systems into business organisations may be that some employees would feel threatened by the new system. They may feel they will be either replaced or inadequately trained to operate the system, in which case the organisation would usually provide training. Another social impact would be that more employees would begin to work from home (teleworking) the remaining workers or the teleworkers may miss the social atmosphere of the working environment. An organisational impact would be that the organisation has the option of globalisation (advertising/web pages) this would make their product available to a much more global market, therefore resulting in more profit (excluding costs of web pages, advertisements etc). Another organisational impact would be that communication with suppliers/distributors/advertisement agencies etc would be
