Summary Introduction

Introduction:

The lungs are one of the most important organs in the respiratory system in human and in other animal. The lungs look like pyramid. It remains in paired. The right lung is wider and shorter than the left lung. The left lung has a smaller volume compared to the right. The lungs are located on the both sides of the heart. The principle function of lungs is to exchange gas (Oxygen) from atmosphere to blood stream and also release Carbon dioxide from blood to atmosphere.

Answer to Problem 1PL

Correct answer:

The correct answer is option (c) 3;2

Explanation of Solution

Explanation/justification for the correct answer:

Option (c) 3;2. Each lung are divided into 2 lobes by folding of pleura as a fissures. The right lung has more lobes compared to left lung. The right lung is separated into 3 lobes namely an upper lobe, middle lobe and lower lobe. These lobes are separated by 2 fissures: one horizontal and one oblique. The horizontal fissure separates the upper and the middle lobe, whereas oblique fissure creates separation between the lower lobe and the middle lobe.

The left lung is divided into 2 lobes, namely an upper and lower lobe. They are separated by oblique fissure. The left lung doesn’t have a middle lobe. So, the correct answer is option (c) 3;2.

Explanation for incorrect answer:

Option (a) 3;3. The right lung is separated into 3 lobes namely an upper lobe, middle lobe and lower lobe. The left lung is divided into 2 lobes, namely an upper and lower lobe. So, this is an incorrect option.

Option (a) 2;2. The right lung is separated into 3 lobes namely an upper lobe, middle lobe and lower lobe. The left lung is divided into 2 lobes, namely an upper and lower lobe. So, this is an incorrect option.

Option (d)2;3.The right lung is separated into 3 lobes namely an upper lobe, middle lobe and lower lobe. The left lung is divided into 2 lobes, namely an upper and lower lobe. So, this is an incorrect option.

Conclusion

The right lung has 3 lobes; the left lung has 2 lobes.
