Standard: Show Content Tip
2b Students know how blood circulates through the heart chambers, lungs, and body and how carbon dioxide (CO2) and oxygen (O2) are exchanged in the lungs and tissues.
Holistic Rating: Moderate coverage of this standard.
Pages 386-393 and 398-402 have the information that could provide depth of coverage, but the presentation has so many extraneous details that the major concepts are not clearly conveyed.
The California Science Framework distinguishes between the functioning of the left and right sides of the heart. The left side of the heart pumps oxygen-rich blood to the tissues, and the right side of the heart pumps oxygen-poor blood to the lungs. This is not explicitly stated in the standard. The model on page 387 and the succeeding pages have this information but do not clearly state it.
Note that in the model (page 387) and in the diagrams of the heart that the right and left sides of the heart are described from the perspective of the person looking out from their body. Thus, the right side of the heart is shown on the left in the diagram. This could be confusing to students unless it is explained to them. |
Aspects that do not help student learning:
The text and graphics on page 392 and 400-401 emphasize the details (names of chambers, vessels, bodily substances) and do not clearly convey the major idea that the lungs receive blood from the heart that is low in oxygen and high in carbon dioxide, and they return blood to the heart that is high in oxygen and low in carbon dioxide.
