Common mistakes in Heart layout and the route blood takes
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Choosing a valve because abnormal mixing is mistaken for ordinary backflow.
- Assuming all venous blood from the intestine returns directly to the heart.
- Skips or reverses the normal chamber and vessel sequence.
- Assigns systemic pumping primarily to the right ventricle.
