Question: 1 / 400

True or False: The left lung has three lobes and the right lung has two lobes.

True

False

The statement is inaccurate regarding the anatomy of the lungs. The left lung actually has two lobes—specifically, the upper and lower lobes—while the right lung consists of three lobes: the upper, middle, and lower lobes. This configuration allows for more space in the right lung due to the presence of the liver, which is situated just below it on the right side of the body, and it is designed to accommodate the variations in thoracic anatomy. The left lung is slightly smaller to make room for the heart, which is located slightly to the left of the midline. Understanding this anatomical distinction is crucial for nursing assessments and interventions related to respiratory health.
