Arrange in order the events that occur in the production of a fever of 39.4 C(10

Question

Arrange in order the events that occur in the production of a fever of 39.4 C(103 F) and recovery from this state.

A. 39.4 C (103 F) temperature is reached and maintained.

B. Prostaglandins(PGs) cause the hypothalamic "thermostat " to be reset from normal.

C. Vasoconstriction and shivering occur as heat is conserved in order to raise body temperature to the 39.4 C(103 F) lever directed by the hypothalamus.

D. Source of pyrogens is removed (for example, bacteria are killed by antibiotics), lowering hypothalamic "thermostat" to 37.5 C(98.6 F)

E. "Crisis" occurs. Obeying hypothalamic order, the body shifts to heat loss mechanisms such as sweating and vasodilation, returning body temperature to normal.

F. Infectious organisms cause phagocytes to release interleukin-1, which then causes hypothalamic release of PGs.

Explanation / Answer

The steps that occurs during production of fever and recovery from it would be,

F. Infectious organisms cause phagocytes to release interleukin-1, which then causes hypothalamic release of PGs.

B. Prostaglandins(PGs) cause the hypothalamic "thermostat " to be reset from normal.

E. "Crisis" occurs. Obeying hypothalamic order, the body shifts to heat loss mechanisms such as sweating and vasodilation, returning body temperature to normal

C. Vasoconstriction and shivering occur as heat is conserved in order to raise body temperature to the 39.4 C(103 F) lever directed by the hypothalamus.

D. Source of pyrogens is removed (for example, bacteria are killed by antibiotics), lowering hypothalamic "thermostat" to 37.5 C(98.6 F)

A. 39.4 C (103 F) temperature is reached and maintained
