The respiratory system is oxygen inhaled into the body and oxygen exhaled from the body. The oxygen is carried throughout all the body systems by blood through the blood vessels. The blood is then pumped by the heart. When a person is resting the blood pumps 5 liters of blood, when the person is exercising the heart pumps 7 times the amount of blood.The amount of air you breathe depends on how active you are. When you start to move around and exercise the muscles in your body send messages to your brain telling you that they need more oxygen. Your brain will then send signals to your muscles that control breathing so they can relax and you take fewer breaths and you can get less tired

As we exercise pyruvate is formed. When insufficient oxygen is available to breakdown the pyruvate then lactate is produced. Lactate enters the surrounding muscle cells, tissue and blood. The muscle cells and tissues receiving the lactate either breakdown the lactate to fuel (ATP) for immediate use or use it in the creation of glycogen. The glycogen then remains in the cells until energy is required. 65% of lactic acid is converted to carbon dioxide and water, 20% into glycogen, 10% into protein and 5% into glucose

Hey there! My name is Bubert Lung and my brother’s name is Theo Lung. Together we make up the lungs of the human body. You can probably guess that we are part of the most important body system in the Human Body System, the respiratory system. The respiratory system has the most essential role in the body, it gives us oxygen! Humans breathe about 20,000 times each day! This would not be possible without the respiratory system. This body system includes the nose, throat, windpipe, and lungs.
The respiratory system gives oxygen to the body’s cells while taking carbon dioxide out of the human body; if you have no oxygen, your body will not be able to take carbon dioxide out. It is also the

Respiration is a process which releases energy from energy-rich molecules such as glucose. The glucose is converted into energy which is usable for life processes. Burning, or combustion, is a reaction between a substance and a gas to release energy. These two reactions have many similarities but are not the same. This essay will identify some of similarities and differences between the two processes.The first similarity is that both respiration and burning use oxidation to release energy. In respiration, oxygen combines with glucose to release energy which can be used in the body. Also some heat is produced to keep the body warm. Burning normally occurs in oxygen (in form of O2) to form

The green plants obtain their energy from sunlight for their life processes. They capture the solar energy and then convert it into a chemical energy. Photosynthesis is an important process , to plants, because they produce glucose and they use the glucose to produce other important and useful chemicals such as fats, proteins and vitamins.

· Leaching
Trees leach nutrients when they are alive, but return nutrients to the soil when they die. When trees are cut down, nutrients get leached but not returned, resulting in infertile soil.
· Soil erosion
When trees are removed, soil can be washed away by rain as tree roots hold soil together (but there will be no tree roots, as there will be no trees).
· Disturbance of the water cycle
Trees take up water, when they are cut down, water runs straight into rivers, causing flooding. also, the local climate gets drier as there is much less transpiration occurring.

The scientific name for burning is "combustion." In most cases oxygen from the air combines with some material that can burn. This produces heat. If the process takes place rapidly, we may see flames or an intense glow which is called fire.Chemically during combustion, two atoms of oxygen from the air combine with one atom of carbon from the fuel to form carbon dioxide.How Fires Get Extinguished?An understanding of how fires burn is essential if a fire is to be extinguished. The three (3) major elements of fire are: a) air; b) heat; and, c) fuel. All three of these elements inter-react to create a fire. If the reaction linking the elements is interrupted, the fire will be extinguished.The

The aim of the experiment is to determine how the temperature of the candle’s surrounding area
affects the time taken for the flame to extinguish.
A chemical reaction is the formation of a new substance. Combustion is a chemical reaction
because it produces a new substance. This is evident as colour, odour, heat and light are
produced. Oxygen and fuel are required for a flame to burn. A candle burns through using liquid
wax as a fuel which has been melted by the flame, then drawn up the wick. This wax is then
vaporised and broken down into hydrogen and carbon molecules (National Candle Association,

Respiration is the process that takes place in every living cell to make energy available to the body. Energy is vital for us to carry out many life processes such as movement and so respiration in essential to life. During respiration glucose and oxygen are used in a reaction that produces energy and gives out carbon dioxide and water as waste products. Glucose is obtained by digestion of food and oxygen is taken from the air during a process called breathing or ventilation. Pulmonary Ventilation is the term given to the movement of air in and out of the lungs; the rate of pulmonary ventilation is defined as the tidal volume multiplied by the number of breaths taken per minute.

The Heart is responsible for the increased heart rate and blood pressure during exercise, this because when there is a higher demand for oxygen during exercise in order for respiration to occur in cells for that extra energy required during exercise, the hearts muscle tissue then begins to contract at a higher rate on order to push the blood around the body through the blood vessels at a much faster rate, ensuring that oxygen needed is carried to the cells through the blood stream in the blood vessels. When the heart contracts the ventricles are responsible for the increased pressure as this part of the heart pushes the oxygenated blood with more force, from out the bottom of the heart and to

Development of the Periodic table
The periodic table is a table of arrangement of chemical elements in order of atomic number. The table is organised in rows, so that elements with the similar atomic structure and similar chemical properties, appear in vertical columns.
Antoine Lavoisier was the first to write an extensive list of elements containing 33 elements and distinguished between metals and non-metals. He was scientist who is known as the “Father of Chemistry”. He named the elements carbon, hydrogen and oxygen, also discovered oxygen’s role in combustion and respiration, also established that water is a compound of hydrogen and oxygen. (1743-1794)

The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood.Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube

ABSTRACTThis paper reviews the contributions of hypothermia and the mammalian diving reflex (MDR) to human survival of cold-water immersion incidents. It also examines the relationship between the victim's age and MDR and considers the protective role played by hypothermia. Hypothermia is the result of a reduced metabolic rate and lowered oxygen consumption by body tissues. Although hypothermia may produce fatal cardiac arrhythmias such as ventricular fibrillation, it is also associated with bradycardia and peripheral vasoconstriction, both of which enhance oxygen supply to the heart and brain. The MDR also causes bradycardia and reduced peripheral blood flow as well as laryngospasm, which

For example, carbon dioxide (CO2) always contains the same relative amounts of carbon and oxygen (about 27 per cent of the mass is made up of carbon). It does not matter whether the carbon dioxide forms from the reaction of sherbet in your mouth, or from the reaction in the engine of a motorcycle, this proportion is fixed because every molecule of CO2 is formed when one carbon atom bonds with two oxygen atoms. This law helped to shape our understanding of the way atoms bond together.
