Flow voids are areas in an image where there appears to be an absence of blood flow, often seen in magnetic resonance angiography (MRA) or magnetic resonance imaging (MRI) scans. They can indicate areas of stenosis or blocked blood vessels. Follow-up testing or consultation with a healthcare provider is usually recommended to further evaluate the significance of flow voids.
Nasal patency refers to the ability of the nasal passages to allow air to flow freely through them. When the nasal passages are open and unobstructed, a person can breathe easily through their nose. Issues with nasal patency, such as congestion or blockage, can lead to difficulty breathing and may require medical attention.

The nervous system regulates the whole body's responses to the environment. The afferent nervous signals flow from sensory organs and other internal receptors to the spine and brain, indicating the current state of the body and its surroundings. The efferent nervous signals flow from the brain and the spine to all the effectors in the body's organs, so the body can change and therefore adapt to its surroundings.

Electrical energy in the brain is generated by the flow of ions across cell membranes. This flow is necessary for transmitting messages between neurons and is essential for brain function.
