After the meeting, Aves handed the letter to the committee chairman.

Do you av time to chat tonight?

During Av, many communities observe traditions of reflection and mourning.

During our hike we spotted several colorful aves perched on the canyon rim.

The choir practiced several Ave Marias before the Sunday service.

During the midnight vigil, the choir's rendition of Ave Maria filled the cathedral with a profound stillness.

The flight school ordered a fresh supply of av-gas for the training planes.

The cardiologist explained that the AV node, a small structure in Koch's triangle near the coronary sinus on the interatrial septum, regulates conduction between the atria and ventricles.

The cardiology fellow explained that a block in the AV bundle was responsible for the patient's bradycardia.

AV bundles transmit electrical impulses from the atria to the ventricles, making them essential to coordinated heart rhythm.
