Associates 'ventricle' with its role in pumping blood, fundamental to cardiovascular health.

Heart Function

Distinguishes between the left, which pumps to body, and right, which pumps to lungs.

Two Ventricle Types

Emphasizes that 'ventricle' is specific to the heart in medical or biological discussions.

Medical Context

Clarifies that in the brain, 'ventricle' refers to fluid-filled cavities, not blood chambers.

Brain Cavities

Links 'ventricle' to brain health and diseases involving cerebrospinal fluid.

Neurological Health

Highlights the differences between the various brain ventricles and their locations.

Distinct Brain Parts

 squirts out of the pulmonary artery. The ventricular valves, called the tricuspid in the right ventricle and the mitral in the left, can be seen through the clear water opening and closing like parachutes as the ventricle is rhythmically squeezed. This flow of water mimics the flow of blood in life.

How the heart actually...

 and I'll page back here so you can see the size of a normal corpus callosum and the size of the person here who has chronic traumatic encephalopathy, it is greatly atrophied. And the same goes for all of the space in the ventricles. These ventricles are much larger.

Why helmets don't...

 coming into the heart. The lower chambers are the ventricles that pump blood out. Between each chamber are valves that open and close and help keep the blood moving. They are the tricuspid, mitral, pulmonary, and aortic valves.
