Final answer:
All statements regarding the ventricles are true, including the ventricles having thicker walls than the atria, the left ventricle having much thicker walls than the right, being separated by the interventricular septum, and receiving blood from the atria(option e).
Step-by-step explanation:
The following statements are TRUE about the ventricles:
- The ventricles have thicker walls than the atria, which allows them to pump blood out of the heart with more force.
- The Left Ventricle (LV) has much thicker walls than the Right Ventricle (RV), because it needs to generate more pressure to pump blood into the systemic circuit, which has a higher resistance than the pulmonary circuit the RV pumps into.
- The right and left ventricles are separated by the interventricular septum, which is a thick wall that prevents mixing of blood from the two sides of the heart.
- The ventricles receive blood from the atria; the atria serve as chambers where blood collects before being pumped into the ventricles.
Therefore, the answer is E) All of the above are true.
