Q. Regarding the heart, which is TRUE? (Solved)
1. the right and left ventricles perform the same amount of work, because the same volume of blood is pumped by each
2. the cross sectional shape of both ventricles is approximately cylindrical
3. the right ventricle pumps by a bellows type mechanism
4. the left ventricle pump action is via reducing cross-sectional area, as a function of radius cubed
5. in pulmonary disease the right ventricle hypertrophies and assumes a crescented shape in cross section
- c. the right ventricle pumps by a bellows type mechanism
