Verified step by step guidance

1. Step 1: Recall the anatomical position, which is the standard position used in anatomy to describe locations and relationships of body parts. In this position, the body is upright, facing forward, with arms at the sides and palms facing forward.
2. Step 2: Understand the structure of the lungs. The lungs are divided into lobes, which are separated by fissures. The right lung has three lobes: superior, middle, and inferior, separated by the horizontal and oblique fissures.
3. Step 3: Note that the left lung has two lobes: superior and inferior, separated by the oblique fissure. The left lung is smaller due to the presence of the heart, which occupies space in the left thoracic cavity.
4. Step 4: Compare the number of lobes in the right and left lungs. The right lung has three lobes, while the left lung has two lobes.
5. Step 5: Match the correct anatomical information to the answer choices provided in the problem. The correct answer is 'three; two,' as the right lung has three lobes and the left lung has two lobes.
