Science Assessment ~ Topics ~ Human Body Systems ~ Misconception BFM028

The digestive system and the circulatory system are not connected (Buckley, 2000; Carvalho et al., 2004).

Items that test for misconception BFM028 in this project (Original Project) and key idea (Oxygen, carbon dioxide, and molecul…)
