AN IDEALIZED CROSS-SECTION THROUGH THE BODY OF A WHITE STORK SHOWING THE LUNG AND AIR CONNECTIONS

Joel Carl Welty, The Life of Birds, W. B. Saunders Co., 1962

At the middle left is the sectioned trachea (dark oval) and the adjacent syrinx. A primary bronchus (2) connects with the lungs (6) by means of the ventrobronchi (3). Dorsobronchi (4) connect the dorsal surface of the lungs with the primary bronchus. The dorsobronchi and ventrobronchi are connected in the lungs by the minute parabronchi (6); this is where gas exchange between the inhaled air and the blood occurs. The abdominal air sac (E) is directly connected with the primary bronchus; the posterior thoracic air sacs (D) join the primary bronchus through the laterobronchi (5). Diagram courtesy of H.-R.

Wanås Wall , 2002
260 inscriptions in 1800 meters stone wall / 260 inscriptions in 1,800 meters of dry-stone wall
“When Jenny Holzer was invited to exhibit at Wanås, she was fascinated by the historic stone walls that run along the outer boundaries of the park, a descent in the Swedish countryside that tells about the work of older people. She let the stone shaker from the neighborhood sandblast four text series in selected stones. In total there are 260 text lines that appear on a regular basis in the 1.8 km long wall. The artwork begins at the park’s entrance with Truisms.”
