39. Which of the following summaries best describes how the digestive, respiratory and circulatory
systems interact?
a. The digestive system absorbs digested nutrients and water into the circulatory system
while the respiratory system then puts oxygen into the circulatory system. The circulatory
system pumps the nutrients and oxygen through the body to the cells, which take in the
needed materials. Once the blood is emptied of its useful materials, it then goes back to the
digestive and respiratory systems for more needed materials, and the cycle starts over
again.
b. Blood circulates all throughout the body as part of the circulatory system. The blood goes
to the respiratory system to pick up oxygen and drop off carbon dioxide. It also circulates
to the digestive system to pick up nutrients and water. From there, it goes out through
various blood vessels to reach every cell in the body, dropping off nutrients, water and
oxygen along the way and picking up waste carbon dioxide and urine. As the blood makes
its way back to the heart, waste urine is filtered out by the kidneys, then it’s back to the
lungs to start the cycle over again.
c. The digestive system absorbs needed nutrients and water from food and carries it to all the
cells of your body. The respiratory system collects oxygen and delivers it to all the cells of
your body. The circulatory system carries blood to all the cells in your body. Each system is
continually collecting and delivering needed materials to all the parts of your body, in a
continuous cycle.
d. Blood goes to the lungs where it collects oxygen in the lungs. Then it goes to the circulatory
system through the arteries. Then the blood goes to the digestive system where it picks up
nutrients and water. From there, blood goes back to the circulatory system to get to other
parts of the body. Blood enters the cells, dropping off nutrients and water. Blood then reenters the circulatory system and exits again when it gets to the respiratory system, where
it drops off carbon dioxide. Blood then leaves the respiratory system again to go back to the
circulatory system. Blood is now going to collect more cell waste, which it will filter out
using the kidneys. Then it goes back to the alveoli, and the cycle starts over.
