The Respiratory System The human respiratory system plays a very important part in our bodies. Without it‚ we wouldn’t be alive! We need air to move through our bodies at all times. Breathing‚ is a key necessity for life. Our respiratory system is made up of many organs that all work together. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The respiratory system organs all work together‚ like a engine in a car‚ they all have a important role. Some

Usually these systems are running on a mainframe and are based on an outdated technology such as hierarchical or networked database systems and transaction-oriented teleprocessing monitors with fixed panels. Although the technology with which they have been implemented is out of fashion‚ the application systems themselves are performing critical business functions in an acceptable and

Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth

URINARY SYSTEM This system consists of the KIDNEYS‚ URETERS‚ URETHRA‚ and BLADDER. Not many structures‚ but very important. Functions: 1. Regulate electrolytes (K‚ Na‚ etc) in body 2. Regulate pH in blood 3. Regulate blood pressure 4. Regulate blood volume 5. Removing metabolic wastes (chemicals produces by chemical reactions in the body are excreted). This is the least important of the kidney’s functions. You can survive for a few weeks without excreting waste products in the urine‚ but hour

Operating Systems Task 1 An operating system (OS) is a part of software which manages the operation of a computer. It controls the hardware and software of a computer‚ without it a computer would be useless. DOS Disk operating system (DOS) was released in 1981. It will load from a floppy disk each time a computer starts. DOS uses a command line interface. Command line interface can be difficult to use if you aren’t trained or experienced in using it. DOS is the predecessor to windows. DOS is

Operating System An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. It is a program designed to run other programs on a computer. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software
