We call the system involved in this Endoderm.

The Endoderm's main function is to respond to internal signals.

The endoderm is the cover tissue of the respiratory, intestinal, thyroid and gill sac derivatives.

Endodermic tissues are controlled by the brain stem; lungs, esophagus (lower third), cylindrical epithelium of the gastrointestinal tract, liver, parenchyma (organ tissue) pancreas, parotid gland, salivary glands of the lower tongue lacrimal gland, thyroid gland, primal source of intestinal flora (enteroidea), oral and rectal submocose mucosa, collecting tubes of the kidneys, pituitary gland and the entire intestine.

Endoderm smooth muscle is controlled by midbrain; smooth muscle layer of the blood vessels, intestinal muscles, uterine muscle and part of the heart muscle; the entire atrium and 10% of the ventricle.

Endoderm sometimes reacts with fungi. The max temperature is 37.2

Endoderm requires a lot of proteins. For the digestion of proteins you need Trypsin.

Proteins are right-handed.

The greatest need for proteins is during childhood when everything is under construction, but there is also a greater need for proteins during illness and recovery.

When the problem occurs, there is often an increase in organ function.

When the problem is addressed there is often fungal bacteria and night sweats.

The most involved hormones are Oxytocin and Melatonin.
