Download Fever and Vomit

Anti-Homeostasis


Bacteria and pathogens are everywhere, in the food we eat,
the air we breath, the ground we walk on.
What protects humans from these bacteria's and pathogens
from entering our systems and what is our bodies response if
they do enter?

The immune system consist of:
◦
◦
◦
◦
◦
◦
◦
Lymph Glands and Vessels
Appendix
Tonsils
Bone marrow
Spline
Thymus
Skin

The Hypothalamus is our “thermostat” that
regulates our internal temperature, a balance
between the internal temperature (metabolism) and
heat that is lost to the environment (the human
body is warmer than the AC setting) 98.6 degrees

A fever occurs in response to infection, allergies or trauma.
Fever inducing agents (Pyrogens) are released by body
immune system (white blood cells) or infectious bacteria.
A “fever” is the resetting of the thermostat and therefore a
higher body temperature. Sometimes localized (cut).
The chills are the body preserving warmth for the core and
the extremities get cold. Sweats occur after the fever and
infection is gone and the body is releasing excess heat.
High temps inhibit growth of bacteria but speed up reactions
that help the body repair itself. Increased heart rate, delivery
of white blood cells to infection.
Pyrogens are stable at boiling water temperatures.

Vomit (spew, barf, ralph soup, puke) is a result of spasms of
the stomach muscles.

Causes include but not limited to pathogens in the stomach,
motion sickness, nausea, or infection.

Vomit is typically bile and partially digested food. Are there
other names for vomit?

Sometimes the CNS tells the stomach to spasm, other times
from the inner ear (balance) to brain to CNS.

Afterwards tired, and after a few moments, feel better, drink
water.
