১.
Which is the embryologic counterpart to the right middle lobe of lung?
  1. ক
    ক) Cardiac notch
  2. খ
    খ) Lingula
  3. গ
    গ) Pulmonary ligament
  4. ঘ
    ঘ) Hilum
ব্যাখ্যা
The left upper lobe contains the cardiac notch, where the left ventricle and pericardial sac lodges. The Lingula (which is the embryologic counterpart to the right middle lobe) lies just beneath the cardiac notch.
