Since the topic of viruses is very popular due to the current Corona pandemic, some general factual background information on viruses is included here. From a biological perspective, it is exciting to understand in more detail what processes the small particles in our body produce. Without our cell mechanisms they would not be able to spread at all, which is why it is to their advantage not to cause too much damage to our organism. They could also bring us medical benefits, for example in cancer research.
The miracle heart: it beats on average 60 times a minute, 4,000 times an hour and 95,000 times a day. It is our engine of life, pumps around 70 milliliters of blood into our veins with just one heartbeat and transports around 300 liters of blood through our body in an hour. Without the heart muscle, all of our organs, cells or tissue could not be supplied.
