Pathway of a Glucose Molecule as it Travels Through the Human Body
Copy and paste the steps for each molecule into the correct order.
STEP |
ORDER 1-12 (1 is entry into the Body and 12 is used in the Cell) |
COLOUR Pink for the respiratory system Blue for the circulatory system Green for the digestive system |
✓ where active transport occur. ★ where passive transport occurs |
passes through aortic valve |
|||
absorbed by a venule in the villus |
|||
passes through mitral valve |
|||
enters a capillary at the site of a body cell |
|||
enters lungs |
|||
enters the stomach |
|||
CO2 and H2O are exhaled during respiration |
|||
enters left atrium |
|||
enters aorta |
|||
enters left ventricle |
|||
used by the cell in the process of cellular respiration to produce ATP |
|||
CO2 and H2O enter into the alveoli of the lungs |
|||
returns to the heart via the inferior vena cava |
|||
absorbed by a villus lining the small intestine |
|||
transported to the liver |
|||
passes through pharynx |
|||
returns to heart via pulmonary vein |
|||
the waste products of cellular respiration leave the mitochondria and enter the cytoplasm of the cell |
|||
passes through tricuspid valve |
|||
passes through pulmonary valve |
|||
diffuses from the capillary into a body cell |
|||
travels to a part of the body and enters an artery |
|||
enters right ventricle |
|||
enters the esophagus |
|||
CO2 and H2O leave the cell and enter a venule to return to the heart/lung blood system |
|||
enters the mouth (oral cavity) |
|||
passes through pyloric sphincter |
|||
enters pulmonary artery |
|||
enters the right atrium |
|||
enters the small intestine |
Once they are in the correct order, highlight the steps that take place in the different organ systems as follows:
Put a checkmark ✓ beside any step where active transport across a cell membrane is taking place.
Put a star ★ beside any step where passive transport across a cell membrane is taking place.
Digestive system GREEN:
Enters the mouth (oral cavity)
Passes through pharynx
Enters esophagus
Enters stomach
Passes through pyloric sphincter
Enters small intestine
Absorbed by a villus lining the small intestine (active transport)
Absorbed by the venule in the villus (passive transport)
Transported to the liver
Circulatory system BLUE:
Returns to the heart via the inferior vena cava
Enters the right atrium
Passes through the tricuspid valve
Enters right ventricle
Passes through the pulmonary valve
Enters pulmonary artery
Returns to heart via pulmonary vein
Enters left atrium
Passes through mitral valve
Enters left ventricle
Passes through the aortic valve
Enters aorta
Travels to a part of the body and enters an artery
Enters a capillary at the site of a body cell
Diffuses from the capillary into a body cell (active transport)
Used by the cell in the process of cellular respiration to produce ATP, CO2, H2O
The waste products of cellular respiration leave the mitochondria and enters the cytoplasm of the cell
CO2 and H2O leave the cell and enters a venule to return to the heart/lung blood system (passive transport)
Respiratory system PINK:
Enters lung
Enter into the alveoli of the lung
CO2 and H2O are exhaled during respiration (passive transport)
