Macrophages

Using the receptors on their surface and through the facilitation by immunoglobulins that attach to the foreign matter, macrophages 'hold' the foreign bodies in the body and 'ingest' them through phagocytosis. Lysozymes in the cells then in 'digest' the foreign matter.

Is a heat pack safe for period pain ?
OLga [1]

Answer:

I hope this hepls :)

Explanation:

Heat therapy is said to work because of its analgesic properties or its ability to bring blood to the area which can penetrate deep into the muscular tissue. However, heat therapy is also said to work because it is comforting on a psychological level. According to Lorimer Moseley “to reduce pain, we need to reduce credible evidence of danger & increase credible evidence of safety” and applying heat makes us feel safe. Why? Because the cold kills!  

Despite this, there is little evidence to show that it helps alleviate pain at certain trigger points  (small patches of acutely sensitive soft tissue) in the body and there is less evidence to show that it works for period pain. One study has claimed that heat can work for period pain however the researchers failed to differentiate if their exercise programme or the psychological effect of feeling warm eased their pain. This kind of testing means that other variables influence participants’ perception of pain and we can’t be certain if the heat therapy actually helped. What we do know is there are certainly drawbacks to this kind of treatment.

How does a scientific explanation differ from a nonscientific explanation?
Talja [164]
A scientific explanation is backed up with data, experiments, observations, and has a large amount of evidence. A non-scientific explanation is usually backed up with beliefs, and opinions. There is no "science" behind that type of explanation.
