Study Notes
Fever
- Fever, also known as pyrexia, is a higher than normal body temperature.
- A fever is a protective response to infection caused by pathogens such as bacteria, fungi, and viruses.
- During an infection, the body activates immune cells, including white blood cells, which produce chemicals called pyrogens.
- Pyrogens travel through the bloodstream to the hypothalamus in the brain, which regulates body temperature.
- Pyrogens bind to receptors in the hypothalamus, causing the body temperature to rise.
- The elevated body temperature aims to kill off pathogens that are sensitive to temperature changes.
- A persistent fever requires medical attention.
- Normal body temperature is between 97 and 99.6 degrees Fahrenheit.
- A rectal temperature over 100.4 degrees Fahrenheit is considered a fever.
- An oral temperature over 99.6 degrees Fahrenheit is considered a fever.
