The importance of good blood vessels in tumors
Enkel voor leerlingen vanaf de 3de graad, de labodag wordt in het Engels gegeven, Blood vessels provide all growing tissues with oxygen and nutrients. The growth of blood vessels is indispensable for the proper functioning of organs and the repair of tissues. In tumors the vessels are not well formed which causes a decrease in delivery of oxygen and nutrients to the tumors. The tumor tries to remedy this situation by producing growth factors that stimulate the growth of new blood vessels.
