 Explain the physiology of two named body systems in relation to energy metabolism in the body (P4)

• Energy laws
To begin with in this task I am going to talking about the body systems in relation to energy metabolism in the body. Firstly, there are two different laws of energy. The first law of thermodynamic is also known as the conservation of energy and this law states that energy can be transformed but it can’t be created or destroyed. The second law of energy is known as the transformation of energy and this may not be of use or be capable of being measured.
• Forms of energy
There are several forms of energy that exist and the most common form is chemical energy, this form of energy is the chemical bond which joins atoms or molecules with one another, when a new bond is made between two atoms, energy is needed for its formation and it is usually in the form of heat, even though light and electrical energy can be used. Also, when the bond is broken and the atoms are released the energy that was in the bond will also be released. The other forms of energy are light, heat, sound, electrical and nuclear.
• Energy metabolism
Energy is not just need for muscular activity and movement but it is also to circulate blood, lymph and tissue fluids throughout the body, it is also needed for breathing and taking in oxygen, for making new cells for growth and repair, to transmit nerve impulses so we can respond to changes within the environment, and to also build complex molecules like enzymes and hormones from simple molecules made after the digestion of food. Moreover, Catabolism is the breakdown of complex molecules within living organisms to form simpler ones; this is done with the release of energy and destructive metabolism. And anabolism is the synthesis of complex molecules within living organisms from simpler ones together with the storage of energy and...

...Forms of energy: There are various forms of energy needed by the body, such as: heat, sound, light and chemical. Heat is a thermal energy. Heat is able to be transferred to different places through a material, through a moving liquid or gas, and through radiation. Surfaces which are dark are better at absorbing heat energy heat energy than light serves which are shiny. Sound is the movement of energy through substances in longitudinal waves. Sound is produced when a force causes an object or substance to vibrate this is when the energy is transferred through the substance in a wave. The energy in sound is far less than other forms of energy. Light is a form of energy which our sense of sight can detect. It is made of electro-magnetic radiation and travels in a straight path. The speed of light travels at about 300,000 kilometres per second, meaning that nothing travels faster than light. Chemical energy is an energy that is stored in chemicals, such as sugar and gasoline. Chemical energy is the energy in a substance that can be released by a chemical reaction. Laws of energy conservation: The Law of Conservation of Energy states that energy cannot be created or destroyed, just transformed from one form to another. These forms can include kinetic and potential energy as well as light, heat and sound. Energy can also be transferred between objects. Since energy cannot be created or destroyed, the amount of energy present in the universe is always the same. It is......

...Energy keeps all living organisms alive, as they need a continual supply of energy to function in order to survive. Some of these processes are continuous such as, metabolism, which is the chemical reactions which occur in the body, these occur by using or releasing energy from chemical substances. Another continuous process which use energy is the transporting of molecules in order for them to break down, and to build new ones. The breakdown of large molecules into their simpler forms to release energy is known as catabolism, for example, when glucose is used in a cell to release energy. And the opposite reaction, is called anabolism. This is when energy is used to build complex structures from simple cells, for example, tissue growth and repair. Catabolism and anabolism, are the chemical reactions which are known as metabolism. Whereas other processes such as, muscular contraction and movement only happen at certain times. The role of energy is essential for muscular activity and movement, but also for the circulation of blood, lymph and tissue around the body, for breathing and taking in oxygen, for making new cells for growth and repair. Energy is also used to transmit nerve impulses to which make the body respond to changes in the environment, and to help build complex molecules such as enzymes, and hormones. Energy can’t be created or destroyed; although it can be transferred from one form to another. There are two laws of energy: the conservation of energy and the......

...Chapter 6: CPU Scheduling • • • Basic Concepts Scheduling Criteria Scheduling Algorithms Operating System Concepts 6.1 Basic Concepts • Maximum CPU utilization obtained with multiprogramming. • CPU–I/O Burst Cycle – Process execution consists of a cycle of CPU execution and I/O wait. – Example: Alternating Sequence of CPU And I/O Bursts – In an I/O – bound program would have many very short CPU bursts. – In a CPU – bound program would have a few very long CPU bursts. Operating System Concepts 6.2 1 CPU Scheduler • The CPU scheduler (short-term scheduler) selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them. • A ready queue may be implemented as a FIFO queue, priority queue, a tree, or an unordered linked list. • CPU scheduling decisions may take place when a process: 1. Switches from running to waiting state (ex., I/O request). 2. Switches from running to ready state (ex., Interrupts occur). 3. Switches from waiting to ready state (ex., Completion of I/O). 4. Terminates. • Scheduling under 1 and 4 is nonpreemptive; otherwise is called preemptive. • Under nonpreemptive scheduling, once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. Operating System Concepts 6.3 Dispatcher • Dispatcher module gives control of the CPU to the process selected by the short-term scheduler;...
