• A. Right lung - 2 fissures - 3 lobes - 10 segments
• B. Left lung - 1 fissure - 2 lobes - 8 segments
• C. Left lung - 2 fissures - 3 lobes - 10 segments
• D. Damage to one of the segments in the lung lobes will not affect the functioning of the other.

Answer 1

Answer: (A), (C)

The correct options are
A

Right lung - 2 fissures - 3 lobes - 10 segments

C

Left lung - 2 fissures - 3 lobes - 10 segments

Carbon dioxide and water are end products of respiration. where water is eliminated in the form of sweat and urine. about 7% of carbon dioxide is dissolved in plasma water 23% as carbaminohaemoglobin and 70% as bicarbonate. the carbon dioxide and bicarbonate is converted back to carbon dioxide in the lungs and it is diffused through Alveoli.
