Respiratory System

The video explores the human respiratory system, detailing the pathway of air from the nasal cavity to the lungs, where gas exchange occurs. It highlights the collaboration between the respiratory and other body systems, such as the circulatory and muscular systems, to maintain homeostasis. The video also compares respiratory systems in various organisms and discusses respiratory health issues and careers. Key concepts include the anatomy of the respiratory system, the process of gas exchange, and the role of surfactant in lung function.

How does the nervous system regulate breathing?

What is surfactant and why is it important for alveoli?

Discuss the impact of premature birth on lung development and the role of artificial surfactants.
