The figure shows diagrammatic view of human respiratory system with labels A, B, C and D. Select the option, which gives correct identification and main functional and/or characteristic.
1 A-trachea-long tube supported by complete cartilaginous rings for conducting inspired air
2 B-pleural membrane-surround ribs on both sides to provide cushion against rubbing
3 C-alveoli-thin walled vascular bag-like structures for exchange of gases
4 D-lower end of lungs-diaphragm pulls it down during inspiration.
Explanation:
B - Alveoli are thin-walled vascular baglike structures for exchange of gases. A - Trachea or wind pipe is an air conducting tube through which transport of gases takes place. C - Pleural membrane is double layered which reduces friction on the lung surface. D - Diaphragm is involving in the inspiration and expiration process of breathing.

The dorsal, ventral, lateral and lower side of thoracic chamber is bounded by ____ respectively
1 Vertebral column, sternum, ribs, diaphragm
2 Vertebral column, ribs, sternum, diaphragm
3 Diaphragm, ribs, sternum, vertebral column
4 Ribs, diaphragm, sternum, vertebral column
Explanation:
The thoracic chamber is formed dorsally by vertebral column, ventrally by the sternum, laterally by the ribs and on the lower side of the dome-shaped diaphragm

The covering of lungs in human is
1 Peritoneum
2 Pericardium
3 Pleural membrane
4 Glission capsules
Explanation:
The pleura is a thin membrane with two layers. One layer lines the inside of the chest wall. The other layer covers the lungs. Between the two layers of pleura (the pleural cavity) is a tiny amount of fluid. This helps the lungs and chest wall to move smoothly when you breathe
