Question: Whats the myoeardrium structure

Simon Anderson answered on 12 Jul 2023:

The myocardium is the muscular part of the heart wall that contains muscle fibers, connective tissues and blood vessels. Helpfully the muscle fibers are found in different directions which lets the muscle to contract and ‘squeeze’ blood in the heart chamber out in a really effective manner. If you look even closer the muscle fibres have special junctions called intercalated discs that help to hold cells together but also helps with the squeezing of the muscle to push blood around by letting messages get around really quickly so all the cells work almost at the same time.

It is really incredible and a great example of how different levels of science look at different components of how things work.
