Which one of the following diagrams shows a system that transports oxygen, water and food to all parts of a human body?Which one of the following diagrams shows a system that transports oxygen, water and food to all parts of a human body?Which one of the following diagrams shows a system that transports oxygen, water and food to all parts of a human body?Which one of the following diagrams shows a system that transports oxygen, water and food to all parts of a human body?

(1) (2) (3) (4)

✔

Students may not choose this answer due to a common misconception that the human circulatory system only transports blood and oxygen and not food and water.

Students may choose this answer due to their understanding of the respiratory system and that it involves oxygen and they may also think that the windpipe is the esophagus and transports food and water.

Students may choose this answer due to their understanding of the digestive system and that it involves water and food and remember that the digestive system requires oxygen.

Students may choose this answer due to their understanding of the skeletal system and that it is part of the whole human body and therefore transports oxygen, water and food to all parts of the body.

Question is easy as question is a knowledge application question in which it only requires to students to recognize the different systems of a human body and its purposes.
