Energy and the Human Body
Energy
Energy is “The ability or capacity to do work”. There are five different types of energy; Chemical, Heat, Sound, Electrical and Light. Chemical energy is energy stored in atoms and molecules; it is released in a chemical reaction, with heat as a by-product.
Heat energy is the result of the movement of particles.
Sound energy is a form of energy which is linked to vibrations of matter. Electrical energy is when electrons move from atom to atom via the use of magnetic forces.
Light energy is a type of kinetic energy with the capability to create types of light people can see as well as undetectable waves.
The first law of thermodynamics is used when managing energy. The first law of Thermodynamics is that …show more content…
For example, a heart beating and muscles moving; all these factors require energy to maintain doing their jobs. If we had no energy, these factors would cease to stop working and we would die. Also, energy is needed to maintain a sufficient body temperature. If we didn’t have energy to maintain our body temperature, we would either start suffering from diseases and disorders such as, Diabetes, Kidney failure and Liver failure etc. at a low body temperature. Or we could suffer from a fever from a high body temperature. Finally, we need energy for all the chemical reactions in our body to take place.
ADP becomes ATP when a phosphate molecule is added to it. Adenosine di-phosphate is a nucleotide consisting of, ‘Organic base: Adenine’, ‘5 carbon sugar: Ribose’ and 2 phosphates. Energy is used to add an additional phosphate to ADP, this makes a molecule called ATP, otherwise known as Adenosine …show more content…
As a person’s lungs expand, air is either sucked through the nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli. Through the very thin walls of the alveoli, oxygen from the air passes to the surrounding capillaries. A red blood cell protein called haemoglobin helps move oxygen from the air sacs to the blood. Blood which contains oxygen travels from the lungs and is carried through a network of capillaries to the pulmonary vein. This vein delivers the blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding
