Answer:
by affecting their behaviour (such as attendance at a screening programme; the food they eat; whether they take prescribed medication), or more directly by affecting a physiological system (such as the immune or cardiovascular systems).
<span>The
majority of medical terms are structured in three parts: Root, Prefix, and Suffix. </span>
<span>
The Root is the part of the word that gives the basic meaning (what the word is
referring to, usually the part of the body it is referring to), for example
Cardi = Heart. In some cases there is more than one root, and they are combined
by a vowel to make it easier to pronounce. </span>
<span>
The Prefix is not necessarily present, but it used to change the meaning of the
word it is placed in front of. An example of a Prefix is A- or AN-, so, anaemia
= no aemia = lack of blood.
It can also specify a time, place, location or status. For example: Intravenous
= Intra (Prefix: within), Ven (Root: the vain) and Ous (Suffix: relating to). </span>
<span>
The Suffix is placed at the end of the Root to indicate its function or change
its meaning. An example of a very common Suffix is –IT IS (inflammation), for
example Arthritis. </span>
<span>
There are some medical terms that do not follow this structure but in this
case, they cannot be deconstructed into single bits. </span>
