  3. গ
    গ) Right atrium
  4. ঘ
    ঘ) The two ventricles
ব্যাখ্যা

  1. ক
    ক) interventricular septum
  2. খ
    খ) trabeculae carneae
  3. গ
    গ) bicuspid valve
  4. ঘ

১৩.
What is the main function of mitral valve?
  1. ক
    ক) To increase the pressure inside the left atrium during systole
  2. খ
    খ) To prevent a drop in pressure in the aorta during diastole
  3. গ
    গ) To prevent backflow from left ventricle to left atrium during systole
  4. ঘ
    ঘ) To add additional blood from left atrium to left ventricle during atrial systole
ব্যাখ্যা
During ventricular systole, blood should flow through the aortic valve into the aorta and not back into the left atrium. The mitral valve prevents blood going back into the left atrium.
