Tetrachloroethylene Essay

Answer 2: The respiratory system functions in the exchange of gases with the outside environment. Oxygen is inhaled through the nasal cavity or the mouth, and it travels to the alveoli in the lungs. There, the capillaries exchange the oxygen for carbon dioxide. The oxygenated blood flows back to the heart from the lungs. It enters the left side of the heart and is delivered to all the body tissues via the aorta. In the capillaries of the body tissues, oxygen is exchanged for carbon dioxide. This deoxygenated blood flows back to the right side of the heart and then to the lung. In the capillaries that run across the alveoli, carbon dioxide is exchanged for oxygen that has recently been inhaled. The carbon dioxide will then be exhaled through the mouth and nasal cavity.

The chemicals inhaled nare arsenic, ammonia, hydrogen cyanide,many of these have been proven toxic or have been proven to cause

- inhalation into the nose, throat and lungs (pathogens in the air or droplets, which can cause e.g. TB),

Contact with any other chemical should be treated as this one. 8. All protective gear listed above should be used in the experiment in the same way. 9. Hair tied back.

➢ The patient may have no respiratory problems, but may still have inhaled carbon monoxide.

2: What type of decay does this substance undergo, and how harmful can it be to those exposed?

has to use a mix of chemicals along with water to actually get the job done, all of the chemicals

Explain the pathophysiology behind this event. For example a person inhales an allergen may be dog hair, pollen, dust, or even mould. This person will be either fine then take a turn or it can take allot of exposure to react now the irritant is in the lungs and

them down drains, or by dumping onto the ground. In addition, vapors emitted by several steps

Exposure to drugs, chemicals of infectious disease at levels that cause illness, pain and distress or death

Ethanoyl anhydride and concentrated sulfuric acid are highly corrosive. Ethanol is flammable, salicylic acid is irritant to eyes and skin. Chemicals were handled in the fume cupboard. Plastic gloves were worn throughout the experiment.

My Thesis Statement is that Dioxin is one of the rogue chemical, which can have bad impacts both human- and animals health, which also can cause at worst the death.

Long term chronic exposure is that the mortality rate from human contact to extraordinary absorptions of these toxins have been documented since the 1900s (ACGIH, 2005). And there has been an accumulative attention on the impacts of hazardous toxins at ever lower levels of exposure. Epidemiological studies have shown correlations between workplace exposure to hazardous substances and the onset of disease, and at the same time there has been a greater than before understanding of the mechanisms by which contaminants exert its poisonous effects.

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside

The lungs can expand and the air is sucked in throughout our nose or mouth. The air travels down our windpipe and into our lungs. After passing through
