Chemicl Interaction in the body during execise

[beyonder]

Hello, I am looking for complete process of biological chemical interaction in the body during execise. I am also looking for any maps of brain switches. Any replys will be greatful.

Thanks,
B.

Does anyone know that? Surely the complete interactions of chemicals in the body at any one time is huge.

During exercise your methabolism speeds up, the secretion of thyroid hormones and epinephrine is increased, the rate of cellular respiration speeds up, the result is a need of extra oxygen. This is done by the influence of epinephrine and norepinephrine on the circulatory system: heart rate rises to almost double it's usual value, the spleenis contracted and releases extra red blood cells. As a result of the intense cellular processes, the temperature of the body increases and sweat glands start to kick in.
Ana many more, and many more things.
Analising everything that happens in the human body at this time from a chemical point of view: every hormone, every enzyme, every neurotransmitter and all cellular processes will fill a good sized library, as Kyle said once. Actually i have a book that is called "Human functional anatomy and physiology". I got it for 50 cents at a college library

What I am really curious about is when the brain decides to utilize fat cells to release their contents for energy, the point after carbs are burned up. The brain must either "flip a switch" and send a signal throughout the body or some enzyme or catalyst is activated/released to signal the body to start burning fat.

Which thyroid hormones are used? T3 and T2?

Also, does sweating induce burning more calories?

Finally, Can someone point me to a complete medical almanac or book or software that has "How the body functions"?

Thanks for responses!

The brain decides to use fat cells to make energy by sending an impulse to the medulloadrenal gland, and releasing adrenaline. Cortizol is also used... And thyroid hormones(Both T3 and T4, there is no such thing as T2)
Sweating consumes energy, like most processes. But the energy consumed is neglijable

(Both T3 and T4, there is no such thing as T2)

There is.....it's a different strain of T4 (Phage)...

Lol, actually i think the T phages are from T1-T7. Just from old genetics classes, you probably know better since you are the site's top virologist
