Study Notes
Respiratory System Overview
- The nose serves as the initial entry point for air, equipped with hair and sticky mucus to filter out dust and germs.
- The windpipe (trachea) is a tube that channels air from the nose to the lungs and vice versa.
- Lungs are muscular structures responsible for oxygen intake and carbon dioxide removal from the bloodstream.
Breathing Mechanism
- The diaphragm is a crucial muscle located below the lungs, facilitating the breathing process by contracting and relaxing.
- Air sacs (alveoli) within the lungs are vital for gas exchange, allowing oxygen absorption into the blood and carbon dioxide elimination.
- Blood transports oxygen to various body parts and returns carbon dioxide to the air sacs for exhalation.
Impacts of Oxygen Supply
- Insufficient oxygen supply leads to impaired organ function, as they rely on a steady supply of oxygen to operate effectively.
- A blocked windpipe would obstruct airflow, causing breathing difficulties and potentially life-threatening situations.
