where can the middle lobe of the lung be assessed
Lobes of the Lungs. There are three lobes in the right lung: 1) right upper lobe, (2) right middle lobe, and (3) right lower lobe. The right upper lobe occupies the upper 1/3 of the right lung. The right middle lobe is typically the smallest of the three, and appears triangular in shape, being narrowest near the hilum.
