Color-enhanced CT scan showing right ventricular strain in a patient with pulmonary embolism, showing right ventricular enlargement and flattening of the interventricular septum. Labelled version.
A normal contrast-enhanced MRI scan of the brain showing clear ventricles and surrounding brain tissue, with no abnormalities detected, indicating normal neurological health.
3D illustration of the human brain with the cerebral aqueduct highlighted in orange and the ventricular system in green, showcasing cerebrospinal fluid flow.
Cerebrospinal fluid protects the brain and spinal cord, cushions shocks, transports nutrients, and removes waste, maintaining the balance of the central nervous system.
At the beginning of heart development, the atria and ventricles form a whole, known as the primitive heart tube.
