The structures labeled AV on the map typically refer to "Atrioventricular" nodes or valves, which are critical components of the heart's electrical conduction system. The atrioventricular node (AV node) is responsible for relaying electrical impulses from the atria to the ventricles, ensuring coordinated contraction. In some contexts, AV could also refer to atrioventricular valves, which separate the atria from the ventricles. The specific interpretation depends on the context of the map being referenced.
there are 15 countries labeled on the map because 8 are not labeled on the map
They are labeled with a star.
What does it mean? labeled number 4 on the map? We don't get it. Sorry.
It seems I don't have the visual context to identify the structures labeled "a." However, if you provide a description or context around the structures, I would be happy to help explain their function.

you av to catch the bus u'll find this on the map note:its only free on wed and sat otherwise u av to pay for it
Chordae tendinae are the string-like structures that attach to the AV valves of the heart.
