The Heart (pg. 123)
Please tell me what you think of my heartbeat sound - a little bit murmury with an almost painful skip!
A color-coded 3D rendering of the ventricular system of the human brain. Rotating colored 3D rendering of the Human four ventricles and connections. Blue - en:Lateral ventricles Cyan - Interventricular foramina (Monro) Yellow - Third ventricle Red - Aqueaductus mesencephali Purple - fourth ventricle Green - continuous with the en:central canal (Apertures to subarachnoid space are not visible) (via Wikipedia)

The discovery that the ventricles (lower chambers) of the heart are a single band of tissue was made as recently as 1972 by Francisco Torrent-Guasp of Spain. This continuous band of muscle is now known as the helical ventricular myocardial band (HVMB) and coils upon itself in a double-helix.The band has a twist where the right ventricle (blue shades) joins the larger and stronger left ventricle (red shades). AO is the aorta, and PA is the pulmonary artery.
I’m trying to let the Lord Jesus into my heart, but I’m dummy thicc, and the clap of my ventricles keeps alerting Satan
Isovolumetric Ventricular Contraction
If the heart was a piece of architecture, then
I envision vaulted ventricles and veins,
And grand arched arteries.
The walls would be thick and strong,
And butressed by the airy-looking lungs.
Blood cells would flock to wonder
At each carefully-constructed chamber,
And I would sit back and rake in
All of the visitor's fees.
