Gas exchange respiratory system

Gas exchange in the lungs can be a difficult topic to teach. Use this infographic to help your students grasp the process.

🫁 Anatomy of the Respiratory System The respiratory is broken down into the upper respiratory tract and the lower respiratory tract. The Upper Respiratory Tract Includes: 1️⃣ Nasal passages 2️⃣ Sinuses 3️⃣ Pharynx 4️⃣ Larynx ⭐️ Key functions: Air filtration, humidification, smell, coughing, speaking, swallowing The Lower Respiratory Tract Includes: 1️⃣ Trachea 2️⃣ Bronchi 3️⃣ Bronchioles 4️⃣ Alveoli ⭐️ Key functions: Gas exchange, sound production, and maintaining acid-base balance

Gas exchange in the lungs is one obvious way that the respiratory system helps maintain homeostasis. However, the respiratory system has several other strategies that keep the body in equilibrium. The mouth and nose are the first lines of defense against invaders trying to enter via the respiratory system.

General Functions of the Respiratory System: - Ventilation - moving air into and out of the lungs - Gaseous exchange - replacing O2 and r...

Gas exchange in humans (and other mammals) happens in the lungs, so first of all you need to know a bit of anatomy. The lungs are protected by the ribcage and are also surrounded by the intercostal muscles.

SYSTEMIC GAS EXCHANGE: This is the unloading of O2 and loading of CO2 at the systemic capillaries. The blue arrows above represent the three mechanisms of CO2 loading and transport. The red arrows above show the two mechanisms of O2 unloading. ALVEOLAR GAS EXCHANGE: Essentially the reverse of the systemic gas exchange.
