The Human Respiratory System 🌬

The respiratory system enables breathing by supplying oxygen to the body and removing carbon dioxide. It includes airways, lungs, and muscles that work together to exchange gases essential for life. Key components of the respiratory system include:

• Nasal Cavity: Filters, warms, and humidifies incoming air.
• Pharynx (Throat): A shared passage for air and food that leads to the larynx.
• Trachea (Windpipe): A tube that carries air from the larynx to the bronchi.
• Bronchi: Two main airways that branch off the trachea into the lungs.
• Neurons: Billions of nerve cells that transmit signals throughout the brain and body.

Breathing occurs as air moves through this system, delivering oxygen to the bloodstream and expelling carbon dioxide. Interactive 3D models help visualize lung function and airflow dynamics.
