The Human Nervous System

Sydney, New South Wales - Australia

The nervous system is essentially a biological information highway, and is responsible for controlling all the biological processes and movement in the body, and can also receive information and interpret it via electrical signals which are used in this nervous system

It consists of the Central Nervous System (CNS), essentially the processing area and the Peripheral Nervous System which detects and sends electrical impulses that are used in the nervous system.

InnerBody: Nervous System
United States

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 nerv

The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The brain is made up of many specialized areas that work together: The cortex is the outermost layer of brain cells. Thinking and voluntary movements begin in the cortex. The brain stem is between the spinal cord and the rest of the brain. Basic functions lik

The Human Respiratory System
United States

The respiratory system helps to breathe - which is inhaling oxygen so that it can be distributed to each cell in the body and collect the waste product carbon dioxide from the cells and expel it back to the atmosphere. The human respiratory system consists of: the nasal passages, Pharynx, Larynx, Windpipe, Lungs. The exchange of the gases - replenishing the blood with oxygen and removing carbon dioxide from it - happens in the lungs. We breathe a

ThinkQuest: Human Digestive System
United States

The human body needs fuel to live. We eat food for fuel. But just getting the food into the body is only a small part of the process. The food must be broken down into chemicals that the body can use. This whole process is called digestion. Some of the organs involved in digestion are the mouth, esophagus, stomach, small and large intestines, gallbladder, pancreas and liver. Follow the process to find out how the body uses the food we eat. Mouth

Human Body: Endocrine System
Turkey

The endocrine system is made up of a group of glands that produce the body's long-distance messengers, or hormones. The endocrine system is instrumental in regulating mood, growth and development, tissue function, and metabolism, as well as sexual function and reproductive processes. The endocrine system is an information signal system much like the nervous system. However, the nervous system uses nerves to conduct information, whereas the end

Human Body Excretory System

The excretory system is in charge of getting rid of bodily wastes and excess water. Jobs of the excretory system: Maintain volume of extracellular (outside the cells) fluid Maintain ionic balance in extracellular fluid Maintain pH and osmotic concentration of the extracellular fluid. Excrete toxic by-products such as urea, ammonia, and uric acid. Parts of the excretory system: Kidneys: Within each kidney are an estimated one mill
