In the parent aside to which this aside is attached, we learned how high and low pressure weather systems are coupled for sustainability.  In that aside we also learned about the bidirectionality of Spin.  Clockwise Spin (CWS) is centripetal (inwardly oriented) and counter clockwise Spin (CCWS) is centrifugal (outwardly oriented).

A primary premise of Quadernity is that Female and Male aspects couple in feedback.  For example, the pulmonary and circulatory systems are coupled together by the actions of cooperating causal agents (one Female and one Male), who exchange OUTput for INput with each other, thereby perpetuating their dynamic feedback.

If their boundaries are closed, the Female’s and Male’s Pulls and Pushes would have no effect.  Spin opens the boundary when appropriate: CWS opens the boundaries inwardly for influx and CCWS opens the boundaries outwardly for efflux.

Dual systems cooperate for sustainability.  Of the two systems, at least one is open to outside space of the dual-system.  Considering the cardio-pulmonary system, it is the pulmonary system that is open to the space outside the system (acquiring a gas (O2) from, and exporting a gas (CO2) into, the body’s outside-space).  The circulatory system, on the other hand, is closed to the body’s outside space (acquiring oxygenated blood from, and exporting de-oxygenated blood into, the inside space of the pulmonary system.

Employing the understandings of coupled systems and gender aspects of Quadernity, we track below the pulmonary and circulatory systems as if they are inextricably entwined gender-related aspects of a feed-back, feed-forward loop of sustainable interactivity.  Explore this in more detail in The Cylindrical Lattice Model.  Scroll down to the section titled Dual Aspects of the Cardio-Pulmonary System.

• Female CWS and inward Pull–The lungs of the pulmonary system obtains from outside-space a resource necessary for the internal circulatory system.
• Female Transition–Inhaled oxygen (O2) transfers to the internal circulatory system via capillaries in lungs.  Oxygenated blood is shuttled to the left cavities of the heart.
• Female CCWS and outward Push–With a systolic contraction the oxygenated blood is Pushed out from the heart through arteries and capillaries to nourish the organs and tissues of the body.
• Female Reset/Rest–After each contraction the heart Rests while it elastically rebounds.
• Male CWS and inward Pull–Diastole is a vacuum-like condition by which the heart retrieves de-oxygenated blood from throughout the body, sucking it through capillaries and into veins, and Pulling it into the right cavities of the heart.
• Male Transition–From there, the blood containing the waste-gas, CO2, moves through a series of valves and into the lungs.
• Male CCWS and outward Push–The lungs exhale CO2 to outside-space.
• Male Reset/Rest–Marking the end of one breath, there is a brief pause before another breath is taken.

At one end of the spectrum (left side of PS or magnets) the Female Pulls INput (oxygen) from the outside-space, and, at the other end of the spectrum (right side of PS or magnets) Male Pushes OUTput (CO2) back into the outside-space.

To an outside observer, the Female Pull of O2 and the Male Push of CO2 are like the opposite poles of a magnet.  The opposite ends of the spectrum are sometimes associated with the terms, yin and yang.  Although both Female and Male Pull and Push, the Female Pull (yin) and the Male Push (yang) are what bridge between the inside and outside-spaces of their coupled systems.  Yin and yang, respectively, refer to the upper-quadrant, open pulmonary system, Female Pull and the Male Push, while disregarding the lower-quadrant, closed circulatory system, Female Push and Male Pull.
