• The human respiratory system Nasal cavity Pharynx (Esophagus) Left lung Larynx Trachea Right lung Bronchus Bronchiole Diaphragm (Heart) Figure 22. 6 A

Thoracic Cavity-Arteries to Know

• The bronchioles end in clusters of tiny sacs called alveoli – Alveoli form the respiratory surface of the lungs – Oxygen diffuses through the thin Oxygen-rich blood walls of the alveoli into Bronchiole the blood Figure 22. 6 C Oxygen-poor blood Alveoli Figure 22. 6 B Blood capillaries

Breathing • • Positive pressure breathing: pushes air into lungs (frog) Negative pressure breathing: pulls air into lungs (mammals) Inhalation: diaphragm contraction; Exhalation: diaphragm relaxation Tidal volume: amount of air inhaled and exhaled with each breath (500 ml) • Vital capacity: maximum tidal volume during forced breathing Regulation: CO 2 concentration in blood (medulla oblongata)

• Smoking causes lung cancer and contributes to heart disease • Smoking also causes emphysema – Cigarette smoke makes alveoli brittle, causing them to rupture – This reduces the lungs’ capacity for gas exchange Figure 22. 7 A, B

The Thoracic Cavity

• During exercise, the CO 2 level in the blood rises, lowering the blood p. H – This triggers a cascade of events Brain Cerebrospinal fluid BREATHING CONTROL CENTERS—stimulated by: Pons Medulla CO 2 increase / p. H decrease in blood Nerve signal indicating low O 2 level Nerve signals trigger contraction of muscles O 2 sensor in artery Diaphragm Figure 22. 9 Rib muscles
