When solid tumors of animals reach a certain size, the center of the tumor begins to die. To prevent this, the tumor can recruit new blood vessels. What purpose does the recruitment of blood vessels to growing tumors serve

Recruitment of the new blood vessel makes it possible for oxygen and glucose to be provided for the purpose of aerobic cellular respiration. The new blood vessels also serves for the elimination of wastes, which include the expulsion of carbon dioxide from the tumor. Some drugs used for the prevention and treatment of cancer blocks the recruitment of these new blood vessels.

Explanation:

Recruitment of the new blood vessel makes it possible for oxygen and glucose to be provided for the purpose of aerobic cellular respiration. The new blood vessels also serves for the elimination of wastes, which include the expulsion of carbon dioxide from the tumor. Some drugs used for the prevention and treatment of cancer blocks the recruitment of these new blood vessels.

The recruited blood vessels provides the fuel for cellular respiration,oxygen and glucose. It supplies oxygen so that aerobic

cellular respiration can occur instead of fermentation,it also supplies glucose to the rapidly growing cells of the tumor,these new blood vessels also eliminate waste from the tumor such as carbon dioxide.

When some anti-cancer drugs are administered,they tend/attempts to block the recruitment of new blood vessels to tumors.
