Circulation Game

Learn what happens as the blood travels through the body.

QuestionAnswer
What happens as the blood travels through the lungs? The blood (around the alveoli) picks up oxygen and gets rid of carbon dioxide.
What happens as the blood travels through the stomach and intestines? The blood absorbs nutrients from the stomach and intestines. It also gives oxygen and takes away carbon dioxide and waste from these organs.
What happens as the blood travels through the liver? The blood picks up carbon dioxide and waste and gives oxygen to the liver. The liver removes toxins from the blood.
What happens as the blood travels through the kidneys? The blood gives oxygen and takes away carbon dioxide. The kidneys remove wastes from the blood.
What happens as the blood travels through the brain? The blood gives nutrients and oxygen. It takes carbon dioxide and other waste from the brain.
What happens as the blood travels through the muscles? The blood gives nutrients and oxygen. It takes carbon dioxide and other waste from the muscles.
What happens as the blood travels through the heart? In this case the heart is acting as a pump. The blood enters the left side coming from the lungs and then goes to the rest of the body. Blood returns from the body into the right side, where it is pumped to the lungs to repeat the trip.
Why do the lungs have thousands of alveoli (tiny little air sacs, surrounded by blood vessels)? These dramatically increase the surface area of blood vessels coming in contact with the oxygen, allowing much more oxygen to be absorbed into the blood (and carbon dioxide to be released from the blood).
