Tetrachloroethylene Essay

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

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 earth and projecting a mixture of chemicals and water into the ground to release the gas

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

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

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.

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

Personal Protection-Readily absorbed through skin. Very destructive of mucous membranes and upper respiratory tract, eyes and skin. Severe irritant. Sublimes at room temperature to yield dangerous levels of vapour. May cause sensitization. May cause damage to the unborn child.

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

The respiratory system and circulatory system are both critical to the life of a mammal. The respiratory and circulatory systems depend on each other greatly. An organism needs both systems to be functioning in order to sustain life. Oxygen needs to be exchanged throughout the body, and the respiratory system and circulatory system are the modes of transportation for the oxygen. The respiratory system establishes the breathing of an animal by the transfer of oxygen, which in return allows the circulatory system to work. According to Barilleaux (2014), the gap between respiratory tissues and aerobic tissues was bridged by the circulatory system.

The respiratory system, also known as the ventilatory system, is a series of organs found in the human body. The system’s primary function is performing respiration – inhaling oxygen from the environment and exhaling carbon dioxide out of the body (K.M Zimmermann, 2016). Oxygen acts as fuel – without it, the body would be unable to function. Carbon dioxide, the by-product of this process, is breathed out as it is toxic to the human body when it builds up (A.M Helminstine, 2016).

Short term acute exposure or high short term exposures, over an 8-hour period, are likely to occur during routine operations and worker activities, but could plausibly involve inhalation, ingestion, and/or skin contact. Pollutants that are absorbed into the blood at extreme concentrations generally affects the brain and, depending on the dose, may lead to symptoms ranging from headaches to irritability to death. Direct skin contact with impurities can cause drying, blistering or an allergic type reaction (red and/or itch). If swallowed, contagions can cause irritation of the mucous membranes of the stomach, mouth, and throat. If the fluid is extracted, severe inflammation of the lungs may result (ACGIH, 2005).

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 primary function of the respiratory system is to allow the efficient exchange of gases in to and out of the body. It is the line between the external situation and the bloodstream.

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.
