Ryan Jerzy Jerzy 1 Cady English 103 26 May 2003 "NCAA Football Playoff System" Thesis: The Bowl Championship Series (BCS) formula has been used to determine the top twenty-five teams in NCAA Division I college since 1998. Many think this system is inadequate and should be changed. The alternative is a playoff system that would give more of the top teams a chance to be named the NCAA football National Champion. I.

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture

Energy Systems The body contains three different types of energys systems which all work together to help us to contract our muscles and perform a variation of movements. ATP-PC ATP-PC is an energy source for the body. ATP is a molecule called Adenosine triphosphate it is an energy source for all movements. The ATP-PC Adenosine triphosphate phosphocreatine is for sudden or immediate movements at high intensity‚ this energy source only last for a few seconds around 8-10 seconds. Muscle cells contain

M1- Discuss the role of energy in the body‚ describe the process of cell respiration and give three examples of how energy is used in the human body Every living cell needs energy. The form of energy that we use is chemical energy in the form of glucose that we get in our food‚ mainly from carbohydrates such as bread‚ pasta and potatoes. Living cells cannot function without energy‚ which can then lead to death. To release the energy from glucose‚ oxygen is added (oxidise glucose) by breathing continuously

important in touch because the amount of physical activity our body can tolerate‚ the better we will play for the longest amount of time. ATP/CP system is used by the body to produce ATP quickly in the absence of oxygen. High intensity activities lasting for less than 10 seconds use this energy system as the primary source of energy. E.g. shot-put or 100m sprint. One reaction causes ATP to break down and become ADP‚ releasing phosphate and energy in the process. Aerobic system: - Requires oxygen

The human body is a very complex working system and it requires a lot of energy to function properly. The human body eats food molecules that contain nutrients in order to get the energy needed to function. Once these food molecules are broken down in the human body some of the nutrients are made into glucose‚ which is an energy source. This glucose is not quite usable as one whole thing so our body breaks down even more into other molecules like pyruvate. Eventually the human body needs to make

Discuss the role of energy in the body In our bodies we need energy so that we could do things that are possible such as; move our muscles‚ talk and all the other things that we do. Without energy all humans would be useless not being able to do anything. Energy is needed to extract the oxygen from the areas in our bodies and diffuse it into our bloodstream. As warm blooded we can only digest food and function if our bodies are at a certain temperature and have enough energy‚ and energy is required for
Premium Metabolism Energy
The three systems in our body that work together are cardiovascular‚ respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system also I am going to explain the physiology of the three named body systems in relation to energy metabolism. Respiratory System The respiratory system consists of tissues and organs in your body which are formed into groups. The system includes airways‚ lungs‚ blood vessels and muscles attached

Sense of Touch/Feeling The Skin Senses Consider the skin has remarkable versatility: It protects us against surface injury‚ holds in body fluids‚ and helps regulate body temperature. The skin also contains nerve endings that‚ when stimulated‚ produce sensations of touch‚ pain‚ warmth and cold. Like several other senses‚ these skin senses are connected to the somatosensory cortex located in the brain’s parietal lobes. The Somatosensory Cortex The skin’s sensitivity
