The human respiratory system is a sophisticated network of organs designed to extract oxygen from air and remove carbon dioxide from the body. This vital system enables the gas exchange necessary for cellular respiration and maintaining life.
đŦ Key Components
Lungs provide massive surface area for gas exchange
Diaphragm drives breathing movements
Alveoli are sites of oxygen and CO2 exchange
Airways deliver air to respiratory surfaces
Breathing Fact!
You breathe about 20,000 times per day, moving roughly 11,000 liters of air through your lungs!
đ¯ Learning Objectives
Understand respiratory system structure, explore breathing mechanisms, and learn how gas exchange occurs at the alveolar level.
