This course will focus on conducting the risk assessment and will include the following topics: 1  Definition of an objectionable microorganism. 2  The difference between pathogenic and objectionable microorganisms. 3  The risk if an organism is found in a raw material.  The risk if an organism is found in the environment.
A Honor Society of Nursing (STTI) answered. Usually, the first effect of influenza on the body is a fever with chills and muscle aches. You may also have a fever, fatigue and a headache. Remember, the flu is caused by a group of viruses that infect the respiratory system. As a result, effects on the body often focus on the throat, nose, and lungs. The nose may become congested or runny, the throat may become sore, and a cough may move from dry to wet as the virus runs its course. The common cold primarily produces sneezing, nasal congestion, runny nose, and a sore throat.
The hypothalamusâs mission is to keep the core warm at all costs â sacrificing the extremities if need be. Thatâs why we feel pins and needles in our fingers and toes in extreme cold â the body is keeping its warm blood close to the centre, constricting blood supply in the outer regions such as the end of our limbs. In extreme cold, and especially if bare skin is open to the elements, this effect can end in frostbite. Blood flow is reduced, and the lack of warm blood can lead to tissue freezing and rupturing. So how do other warm-blooded animals living in such climes cope when we canât? Polar animals are either covered in winter coats of fur â which traps warm air close to the body â or else large quantities of fat, sometimes inches thick. Fat does not transfer heat very well, so it keeps it inside the body. Humans, with naked skin and relatively little fat, just arenât built for these environments. But we have learned to mimic these qualities. Scientists in Antarctic stations, for instance, dress in layers upon layers, which traps warm air close to the body like fur does. The other problem with the kind of weather currently affecting the US is that it can create problems with some of the things mankind relies on. Intense cold can bring down power lines due to the weight of ice, cutting power ...
