Question

Lingula structure originates from
A. Superior side of left lung
B. Superior side of right lung
C. Inferior side of right lung
D. Inferior side of left lung

Answer 1

In humans and many other animals, including a few fish and some snails, the lungs are the main organs of the respiratory system. Two lungs are found near the backbone on either side of the heart in mammals and most other vertebrates.

Complete Answer:
Humans have two lungs, a lung on the right and a lung on the left. They are located inside the chest's thoracic cavity. The right lung, which shares room in the chest with the heart, is larger than the left. Together, the lungs weigh around 1.3 kilogrammes (2.9 lb), and the right one is heavier. The lungs are part of the lower respiratory tract that starts at the trachea and branches into the bronchi and bronchioles, receiving air that is inhaled through the conducting region.

The left lung, by the oblique fissure that stretches from the costal to the mediastinal surface of the lung both above and below the hilum, is divided into two lobes, an upper and a lower lobe. Unlike the right, the left lung does not have a middle lobe, although it does have a homologous feature, called the lingula, a projection of the upper lobe. His name means "tiny tongue."

The left lung lingula functions as an anatomical counterpart to the right lung 's middle lobe, with both regions predisposed to similar diseases and anatomical complications. There are two segments of the lingula that are bronchopulmonary: superior and inferior.

The correct Answer is option (A) Superior side of left lung.

Note: To make room for the liver, the right lung is shorter than the left lung. To make room for the heart, the left lung is narrower than the right.
