through our body. The blood moves through pulmonary circulation and then continues on through systemic circulation. Pulmonary and systemic are the two circuits in the two-circuit system of higher animals with closed circulatory systems. As the heart pumps‚ blood is pushed through our body through the entire circulatory system. Oxygenated blood is pumped away from the heart to the rest of the body‚ while deoxygenated blood is pumped to the lungs where it is re-oxygenated before returning to the heart

NERVOUS SYSTEM The nervous system consists of the brain‚ spinal cord‚ sensory organs‚ and all of the nerves that connect these organs with the rest of the body. Together‚ these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions

The digestive system is a combination of organs which have been arranged together to help carry out its particular function of turning food into the energy which is necessary to survive and packaging the excess residue for waste disposal. Digestion involves the breakdown of food into smaller components. The process of digestion has many stages with the first starting in the oral cavity. Within the system‚ food passes through a tube called the alimentary canal‚ more commonly known as the gastrointestinal

thought of the idea of General System Theory back in 1936‚ but hesitated until 1948 when the intellectual climate was more receptive. At the University of Chicago (1937-38) he worked with the Russian physicist Nicolaus Rashevsky. There he gave his first lecture about the General System Theory as a methodology that is valid for all sciences. Systems thinking dates back to antiquity (Mayans‚ Egyptians‚ Greeks) Von Bertalanffy began to develop common systems teachings in lectures during the

1.6 Types of systems The frame of reference within which one views a system is related to the use of the systems approach for analysis. Systems have beenclassified in different ways. Common classifications are: (1) physical or abstract‚ (2) open or closed‚ and (3) “man – made” information systems. 1.6.1 Physical or abstract systems Physical systems are tangible entities thatmay be static or dynamic in operation. For example‚ the physical parts of the computercenter are the officers‚ desks‚ and

different political systems of government which are parliamentary government and presidential government. These two government systems are the most fundamental and dominant government methods in the world. The main issue and debate that has been concerned is that which form of government is more superior to the other. It will provide on the characteristics of parliamentary system and also characteristics of the presidential system. Moreover‚ comparison of main elements of these two systems will be examined

of Urinary System The urinary system consists of the kidneys‚ ureters‚ urinary bladder‚ and urethra. The kidneys filter the blood to remove wastes and produce urine. The ureters‚ urinary bladder‚ and urethra together form the urinary tract‚ which acts as a plumbing system to drain urine from the kidneys‚ store it‚ and then release it during urination. Besides filtering and eliminating wastes from the body‚ the urinary system also maintains the homeostasis of water‚ ions‚ pH‚ blood pressure‚ calcium
