Principle

Every human being possesses 5 to 7 liters of blood which constantly circulates in the body. When circulating, it transports nutrients and heat to wherever needed. The blood also has many other functions, for example, it is responsible for the closure of wounds and it is capable of eliminating various pathogens. But blood itself may be a carrier of pathogens (hepatitis viruses and HIV), even if people appear to be healthy. Any direct contact with the blood of another person must therefore be avoided by all means. For this reason, animal blood or a permanent slide may also be used in the following experiments.
