There are six rings in the windpipe of the lungs and they represent the process and Zeir Anpin. They correspond to the six voices that are referred in Psalms 29 that we sing at the end of the sixth day, Friday evening with the receiving of the Shabbat that is the queen, the Shechina, Malchut.
The mouth is the seventh level from which the sound comes up and out. The six ‘rings’ is the process (Zeir Anpin) that the lungs go through connecting to the light that is coming from the five lobes. The windpipe serves as Yessod and channels everything out of the mouth that is the aspect of Malchut. That completes the process of manifesting the energy of the sound into action.
The windpipe is explained by the Zohar as the ladder that is used by the angels to connect upper and lower.
Genesis 28:7 (from Jacobs dream) “ וַיַּחֲלֹם, וְהִנֵּה סֻלָּם מֻצָּב אַרְצָה, וְרֹאשׁוֹ, מַגִּיעַ הַשָּׁמָיְמָה; וְהִנֵּה מַלְאֲכֵי אֱלֹהִים, עֹלִים וְיֹרְדִים בּוֹ.”
“ And he dreamed, and behold a ladder set up on the earth, and the top of it reached to heaven; and behold the angels of God ascending and descending on it.”
The main windpipe (Trachea) branches to 22 pipes (bronchi) that continue to branch up to 17 millions branches. The 22 is the aspect of the 22 Hebrew letters coming out of the five lobes and in the mouth they are grouped again into 5 that reveal their energy levels.

17 is numerically טוב, meaning ‘Good’ as in Genesis 1:4 “וַיַּרְא אֱלֹהִים אֶת-הָאוֹר, כִּי-טוֹב” “ And God saw the light, that it was good;”
The Light is good and that is the process that goes in the lungs in order to serve the ‘King’ that is the heart between the wings of the lungs.
“ וּפְנֵיהֶם, וְכַנְפֵיהֶם פְּרֻדוֹת מִלְמָעְלָה”
“Thus were their faces; and their wings were spread from above”
“ וְהָיוּ הַכְּרֻבִים פֹּרְשֵׂי כְנָפַיִם לְמַעְלָה, סֹכְכִים בְּכַנְפֵיהֶם עַל-הַכַּפֹּרֶת”
“And the cherubim shall spread out their wings on high, screening the ark-cover with their wings, with their faces one to another;”
The lungs is where YHVH ‘communicates’ the energy of life with us. When breathing stops, the heart also stops, followed by the brain and the soul leaves the body.
Every breath is a gift of Light and life that comes from YHVH and a proper consciousness is important to maximize on receiving the energy and keep a healthy body and soul.
I suggest researching good breathing techniques that could work for you and follow it in a place where there is no spiritual or physical pollution.
