The overload principle
Explanation:
The overload principle is the most basic of all physical activity principles. It says that doing "more than normal" is necessary if benefits are to occur.
Microorganisms such as bacteria, viruses, yeasts and molds can spoil food and may cause a risk to anyone's health. Microbes cause infectious diseases such as flu and measles. But you do have to remember that less than 1% of bacteria can invade our body (the host) and make us ill. So even if it is 1%, that's still 1% that can harm you.
Some examples of how microorganisms affect humans and how they can enter through your body:
Respiratory tract (mouth and nose): Influenza virus which causes the flu.
Gastrointestinal tract (mouth oral cavity): Vibrio cholerae which causes cholera.
Urogenital tract: Escherichia coli which causes cystitis.
Breaks in the skin surface: Clostridium tetani which causes tetanus.
Barrier methods of contraception would include:
1. Diaphragm
2. Sponge
3.Cervical cap
4.Male condom
5. Female condom
6. Spermicide.
Barrier methods of family planning are physical or chemical barriers that function to prevent conception. They have some advantages and disadvantages. For example some advantages of the diaphragm are that it has no effect on a woman's natural hormones, it can be used while breastfeeding beginning 6 weeks after birth. Some disadvantages are that there is increased risk of toxic shock syndrome if diaphragm is left in for more than 24 hours. Also it may have to be used in conjunction with another barrier method to enhance its efficacy.
