Respiratory System Overview

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.
