NUTRITION AT WORK
DIGESTIVE
- Teeth chew the food and it mixes with saliva.
- The food goes down the esophagus.
- The gastric juices in the stomach break the food into smaller pieces.
- The small intestine absorbs the nutrients from the food and they pass into the blood.
- The large intestine absorbs the water and the waste passes into the colon and out of the body.
RESPIRATORY
-

-
At the end of the small tubes there are small air sacs called alveoli. This is where the oxygen passes into the blood.
CIRCULATORY
The left ventricle pumps blood with oxygen and it comes out into the largest artery called the aorta.
- b. Blood flows through the arteries delivering oxygen and nutrients to the cells. At the same time, blood absorbs carbon dioxide from the cells.
- d. Veins carry the deoxygenated blood to the heart. This blood contains carbon dioxide.
- a. Deoxygenated blood in the veins flows back into the right atrium and then into the right ventricle.
- c. The right ventricle pumps the deoxygenated blood to the lungs.
- e. In the lungs, the blood picks up oxygen and releases carbon dioxide.
- g. The oxygenated blood in the lungs goes back to the heart through the veins.
- f. The oxygenated blood from the lungs goes into the left atrium and then into the left ventricle. The journey starts again.
