Respiratory System
• Provides oxygen to cells for cellular respira8on.
• Oxygen can’t be stored so must be provided con8nually

The Conduc8ng Zone
• Carries air to the lungs. • Humidifies, and purifies incoming air.

Path of Air Into Lungs
• Air comes in through the nose or mouth. The inside of the nose is covered with a layer of mucus to clean the air.
• Air travels down your pharynx (throat), past your larynx (voice box), and through your trachea (windpipe) into the bronchial tubes in your lungs.

The Respiratory Zone
• Where gas exchange occurs including puKng oxygen into your blood and removing carbon dioxide from your blood.
• Comprised of the lungs and its parts

Lungs
• Alveoli -‐ 8ny air sacs at the end of the bronchial tubes that are surrounded by capillaries.
• Oxygen moves through the walls of the alveoli and into the blood.
• Carbon dioxide moves out of blood and into the alveoli.

Chest Cavity
• Lungs are protected by the rib cage • Diaphragm – a dome-‐shape muscle that the lungs rest on

Breathing
• Inhaling – the diaphragm contracts pulling air into the lungs to provide oxygen to the blood.
• Exhaling – the diaphragm relaxes pushing air out of the lungs to remove carbon dioxide from the blood.

Asthma
• causes the airways of the lungs to swell and narrow, leading to wheezing, shortness of breath, chest 8ghtness, and coughing.

Emphysema
• Makes it difficult to breathe. • Most common form of lung disease. • Smoking is the leading cause for emphysema.
