Blood gas transport essay

Transport of oxygen and carbon dioxide through blood during respiration Balbir I. The exchange of oxygen and carbon dioxide takes place in between the lungs and blood. The greater part of oxygen diffuses into the blood and at the same time, carbon dioxide diffuses out.

Oil spill An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution.

The term is usually applied to marine oil spills, where oil is released into the ocean or coastal watersbut spills may also occur on land.

Oil spills may be due to releases of crude oil from tankerspipelines, railcars, offshore platformsdrilling rigs and wellsas well as spills of refined petroleum products such as gasolinediesel and their by-products, heavier fuels used by large ships such as bunker fuelor the spill of any oily refuse or waste oil.

Spilt oil penetrates into the structure of the plumage of birds and the fur of mammals, reducing its insulating ability, and making them more vulnerable to temperature fluctuations and much less buoyant in the water.

Cleanup and recovery from an oil spill is difficult and depends upon many factors, including the type of oil spilled, the temperature of the water affecting evaporation and biodegradationand the types of shorelines and beaches involved. Waste oil Waste oil in the form of motor oil Waste oil is oil containing not only breakdown products but also impurities from use.

Some examples of waste oil are used oils such as hydraulic oiltransmission oil, brake fluids, motor oilcrankcase oil, gear box oil and synthetic oil.

When waste oil from vehicles drips out engines over streets and roads, the oil travels into the water table bringing with it such toxins as benzene.

This poisons both soil and drinking water. Runoff from storms carries waste oil into rivers and oceans, poisoning them as well. Sustainable energy and Energy conservation Conservation and phasing out[ edit ] Many countries across the World have subsidies and policies designed to reduce the use of petroleum and fossil fuels.

Examples include China which switched from providing subsidies for fossil fuels to providing subsidies for renewable energy. In China positive benefits were observed in the energy system due to higher renewable energy subsidies in three ways.

It made consumption of energy cleaner due to moving for cleaner sources. Secondlyit helped increase the efficiency and third it resolved the issue of imbalanced distribution and consumption.

However from the Chinese experience there were challenges observed. These challenges included economic challenges like initially lower economic benefits for subsidies from renewable energy than for oil.

Other challenges included a high cost of research and developmentuncertainty of cost and potentially high-risk investments. These factors make the development of renewable energy very dependent on government support. However aims of phasing out fossil fuels and petroleum use may also present economic benefits such as increased investment.

This strategy may help achieve social goals for example reduction in pollution which might translate to better environmental and health outcomes. This can include changing production methods and modes of transportation. Some of the alternatives have their strengths and limitations that might impact on the possibility of adopting them in the future.

Using corn-based ethanol might be an alternative to using petroleum. However, studies that concluded that corn-based ethanol uses less net energy do not factor in the co-products of production.

Current corn-ethanol technologies are much less petroleum intensive than gasoline however have the GHG emission levels similar to gasoline. The future of biodiesel might be adopting cellulose ethanol technology to produce biodiesel as that technology will contribute to a decrease in emissions.

These include solar energy, wind energy, geothermal and hydroelectricity as well as other sources. These sources are said to have much lower emissions, and almost minimal secondary by products. The production of renewable energy is projected to grow in nearly every region in the World. Natural gas is much cleaner than oil in terms of emissions.

For example, in order to switch from crude oil to natural gas there are technical and network changes that need to occur before the implementation can be complete.

Two possible strategies are to first develop the end use technology first or second is to completely change the fuel infrastructure.

Blood has three main functions: transport, protection and regulation. Transport. Blood transports the following substances: Gases, namely oxygen (O 2) and carbon dioxide (CO 2), between the lungs and rest of the body; Nutrients from the digestive tract and storage sites to the rest of the body;.

Draw a simple diagram of the gas exchange system in humans. 5 marks SL. Essay No. Pollution. The word pollution has been derived from the Latin word pollution, which means to make dirty. Pollution is the process of making the environment land water and air dirty by adding harmful substances to it.

This is due to the increased environmental impacts of petroleum and the desire to reduce the use of petroleum. Potential substitutes include cellulose from fibrous plant materials as a substitute for oil-based products.

Plastics can be created by cellulose instead of oil and plant fat can be substitutes for oil to fuel cars. In order for biomass to succeed there needs to be an integration of different technologies to different biomass feedstock in to produce different bio products. Incentives for biomass are a decrease of carbon dioxideneed for a new energy supply and need to revitalize rural areas.

These include measures to reduce oil spillsfalse floors to prevent gasoline drips in the water table and double-hulled tanker ships.

A relatively new technology that can mitigate air pollution is called bio-filtration. Bio filtration is where off-gasses that have biodegradable VOCs or inorganic air toxins are vented out through a biologically active material.Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated.A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion..

The main transport system in human beings (or man) is the 'blood circulatory system' (which is sometimes called just 'circulatory system' for the sake of convenience). In the human circulatory system, blood carries oxygen, digested food and other chemicals like .

The exchange of oxygen and carbon dioxide takes place in between the lungs and blood. The greater part of oxygen diffuses into the blood and at the same time, carbon dioxide diffuses out. Here the question is where the oxygen would go. The most part oxygen (about 97%) is now carried by the.
