Study Notes
Parts of the Respiratory System
- Nose: Equipped with hair and sticky mucus to trap dust and germs, protecting the body’s internal systems.
- Windpipe (Trachea): A straight tube that serves as a passageway for air between the nose and lungs.
- Lungs: Muscular organs crucial for oxygen intake and carbon dioxide removal from the bloodstream.
- Diaphragm: A thin muscle located beneath the lungs that plays a key role in the breathing process by contracting and relaxing.
How the Lungs Work
- Air exchange occurs in tiny balloon-like structures called air sacs (alveoli) in the lungs.
- Oxygen from inhaled air is absorbed by the blood; this oxygen is then distributed throughout the body.
- Carbon dioxide-rich air from body tissues returns to the air sacs to be expelled during exhalation.
Practice Questions Insights
- Nose: Functions to trap airborne particles using hair and mucus.
- Windpipe: Essential for connecting the respiratory system components and facilitating airflow.
- Air sacs: Critical for gas exchange between air and blood, highlighting their importance in respiration.
- The diaphragm’s role is fundamental in regulating breathing, moving volume in and out of the lungs.
- Lack of oxygen results in organ dysfunction, emphasizing the need for adequate oxygen supply.
- A blocked windpipe poses a significant threat to respiration, potentially leading to suffocation.
