Read the paragraph from the section "Thick Tissue With Tiny Blood Cells."
"One of the big problems in
engineering heart muscle is getting
blood flow to all of the cells," said
Gaudette. He is a professor of
biomedical engineering at WPI. "Heart
muscle is pretty thick," he added.
Current technology cannot construct
tissue thick enough to replace a
damaged heart. One challenge is that
the tissue also has to allow for the tiny
blood vessels. These are needed to
deliver oxygen.
Which word from the paragraph helps the reader
understand the meaning of "engineering"?
A
construct
B
damaged
C

D
deliver
