प्रश्न
Give scientific reason.
Left ventricle is thick than all other chambers of heart.
उत्तर
i. The thickness of the myocardium of the four chambers varies according to the functions of each chamber.
ii. The thin-walled atria deliver blood into adjacent respective ventricles.
iii. As compared to the right ventricle, the left ventricle pumps blood at great distances to all other parts of the body at higher pressure, and resistance to blood flow is larger. Therefore, the left ventricle is thick as it requires strength to withstand the high pressure.
