Air is the ocean we breathe, air supplies us with oxygen which is essential for our bodies to live. However, human activities can release particles into the air, of which can cause problems such as smog, acid rain, the greenhouse effect, and holes in the ozone layer. Each of these problems has serious problems for our health and well being as well as for the whole environment. Therefore, preventing air pollution is not only the duty of an individual but...

High-flow nasal cannula (HFNC) oxygen therapy comprises an air/oxygen blender, an active humidifier, a single heated circuit, and a nasal cannula. It delivers adequately heated and humidified medical gas at up to 60 L/min of flow and is considered to have a number of physiological effects which include: reduction of anatomical dead space, PEEP effect, constant fraction of inspired oxygen, and humidification. HFNC has been gaining attention as an innovative respiratory support for critically ill adult patients. High flow nasal...

Here is an explanation of how the different types of cell respiration, aerobic and anaerobic, can be used by skeletal muscles during exercise. Moreover, after this I’ll discuss how multiple body systems normally work together for oxygen to enter the body and reach cells. To begin with, it’s needed to know that the key systems that work hand in hand to provide cells with oxygen are circulatory and respiratory system. The intake of oxygen is crucial in cellular respiration. The...

Oxygen diffusion is essential for the survival of living animals. Differences in the surface area and relative thickness of respiratory surfaces among vertebrates have been shown to influence the rates of oxygen diffusion and the levels of aerobic activity (Gillooly et al., 2016). Different animals have developed specialized organs in which gas exchange can take place, such as the gills in fish and the lungs in humans. These specialized organs facilitate the transportation of oxygen molecules from the lungs to...

The combustion or the burning of fuels, is perhaps the most common and obvious example of oxidation and reduction. Combustion is also that process which converts the potential energy of fuels into kinetic energy (heat and light). Most fuels (gasoline, diesel oil, propane, etc.) are compounds comprised primarily of carbon and hydrogen. These hydrocarbons represent an excellent source of potential energy which is released as heat during the combustion process. A common example is the oxidation of propane, the fuel...

The respiratory and circulatory systems work together to deliver oxygen to cells of the body (the lungs through air exchange, and the circulatory system by delivery of haemoglobin containing red cells to the capillaries where oxygen is released into the tissues) and removal of carbon dioxide.The circulatory system delivers nutrients absorbed through the walls of the small intestine to other organs (such as the liver, muscles, brain, heart), and delivers oxygenated blood to the digestive system.You breathe in oxygen into...

The purpose of this experiment was to show the properties of hydrogen and oxygen gas reacting with fire. Both H2 and O2 were produced from reactions of other chemicals. H2 gas was produced from a reaction of hydrochloric acid and zinc, and oxygen was generated from the decomposition of hydrogen peroxide. After each gas was produced, they were tested for combustibility and flammability, and the observations were recorded in this lab. For the production of oxygen gas, 30 mL of...
