Tumors Can Deprive Cells of Oxygen

question 9

Multiple Choice

Tumors can deprive cells of oxygen. This happens through angiogenesis, which is

• A) When tumors block the blood stream, preventing oxygen from getting to some of the cells "downstream" from the blockage
• B) When tumors cause blood vessels from the circulatory system to grow into the tumor, preventing oxygen and nutrients from traveling to other cells
• C) When tumors secrete chemicals that convert oxygen to carbon dioxide, which other cells can't use
• D) When tumors lodge in the lungs, blocking oxygen uptake
• E) When tumors grow so fast they force the heart to slow down, slowing the transport of oxygen through the body
