|
|
The left ventricle must force blood into all the capillaries of the lungs
|
|
|
the left ventricle doesn’t skip leg day
|
|
|
This is false, the walls of the right ventricle are thicker
|
|
|
Blood from the left ventricle is pumped throught the entire body
|
Detailed explanation-1: -The left ventricle pumps blood to all parts of the body, while the right ventricle only pumps blood to the lungs. Therefore, the wall of the left ventricle is thicker than the right ventricle.
Detailed explanation-2: -The left ventricle is thicker than the right ventricle because the left ventricle has to pump blood into vessels.
Detailed explanation-3: -The left ventricle muscular wall is thicker than the right ventricle because it has to generate higher pressure to overcome the greater resistance of the longer systemic circulation route versus the shorter pulmonary circulation route.
Detailed explanation-4: -The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria.
