Study Notes
Respiratory System Overview
- The respiratory system facilitates breathing and gas exchange, essential for oxygen intake and carbon dioxide removal.
The Nose
- Air enters through the nose, which contains hair and sticky mucus.
- Hair and mucus trap dust particles and germs, preventing them from entering the body.
The Windpipe
- The windpipe, also known as the trachea, serves as a conduit for air to travel between the nose and the lungs.
- It is a straight tube that allows for efficient airflow.
The Lungs
- The lungs are muscular organs that play a pivotal role in gas exchange, taking in oxygen and expelling carbon dioxide from the bloodstream.
- Comprised of numerous structures, they facilitate the crucial exchange of gases.
The Diaphragm
- The diaphragm is a thin muscle located beneath the lungs.
- It moves upward and downward, playing a critical role in inhalation and exhalation.
The Air Sacs
- Tiny, balloon-like air sacs (alveoli) in the lungs enable gas exchange.
- Surrounding thin blood vessels absorb oxygen and transport it throughout the body.
- Air rich in carbon dioxide returns to the air sacs to be exhaled.
Potential Issues
- Insufficient oxygen supply to body organs can impair their function.
- Blockage of the windpipe disrupts airflow, leading to breathing difficulties.
