The brain is an organ that serves as the center of the nervous system for most living things. There are only a few animals that do not have a brain like starfish or jellyfish. The brain is located in the head. It receives messages from other organs. The brain is the most complex organ. In a human, the cerebral cortex has more than a billion neurons. Each of these neurons are connected by synapses. These synapses are connected to several thousand other neurons. Neurons communicate with one…
Brain, Nervous System, & Sensory Systems In humans, the nervous system is the area in which the body processes and sends messages. It is a complicated system that gathers sensory information from the entire body, replies to changes in the body, evaluates request information, begins and implements all bodily activity, and preserves “homeostasis” in the body. An organism nervous system is separated into two systems: the “central nervous system (CNS) and the peripheral nervous system (PNS).” The…
. The 8 major systems within the body are the skeletal system, the nervous system, the endocrine system, the digestive system, the lymphatic system, the urinary system, the circulatory system and the reproductive system. Skeletal system - Bones make up the structure of our body, they are what gives it form. They are hard, and dense and interconnect via joints and are held in place by muscles and tendons. Bones are made of 25% water and 75% solids. the skeletal system protects and shields soft…
Speeding up the operating system (OS) Software utilities can speed up the operating system in numerous ways. Examples of speeding it up by using software utilities include programs that allow the computer memory or processing power to be handled better. The way this works is that the unnecessary processes for your computer can be prevented from running if the user does not a certain process running in the background, the result of this is that the computer performance will run a lot faster once…
Urinary System The urinary system is one of the eleven major organ systems of our body. This organ system is one that is often over looked. The urinary system removes toxins from the blood and maintains the acid-base balance of the body. This system regulates the chemical composition, volume, and electrolyte balance of the blood. The urinary system works in with the respiratory, integumentary, and digestive organs to eliminate waste. Reflexology supports and enhances the urinary system by…
What is the solar system? The solar system is the what we call home, it is the collection of the eight planets and their moons. These celestial objects orbit around the sun, although this was not always the case back in 140 AD Claudius Ptolemy contemplated with the idea or theory of a geocentric universe. The literal definition of geocentrism is having the earth as the center of the universe and the at the other celestial objects orbiting the earth. Theses celestial objects are called planets.…
Endocrine System The endocrine system has to do with the hormones of the body. Hormones are chemical messengers that travel throughout the bloodstream to other tissues. These hormones are secreted by endocrine glands throughout the body. Hormones help with the functions of certain organs and glands and help with digestion, muscle contraction, sex hormones for reproduction, sleep, and much more. They can really dictate how chemicals in the body react. The major function of the endocrine system…

Name and identify the ureter, bladder and urethra Introduction: The urinary system consists of two kidneys. The urinary system performs many functions removing waste, products from the…
As time went on, each of these areas engaged in other economic systems that would meet the financial needs of its people. Within this short essay, it will examine the varying reasons that caused for different economic systems to be developed within each colony and also describe the effect they have had on each of the region 's social form. When looking at both the Northern and Southern economy, they both have unique economic systems that provide stability in each region while also changing the…
Autoimmunity and the Endocrine System Chad Martin Nursing 631 Grand Canyon University December 12, 2015 Introduction The immune system in the human body is protection. Protection not only from infectious disease processes and foreign bodies but from ourselves. The immune system is great to have when working well, however, there can be unintended and serious consequences when the system fails and initiates inappropriate responses to our bodies own cells. Autoimmunity specifically is the…
