📝 Key Points about Alveoli: Structure: 🫁 Tiny, balloon-like sacs. 🫁 Surrounded by capillaries. Function: 🫁 Gas Exchange: Oxygen passes through the alveolar walls into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled. 🫁 Surface Area: The large number of alveoli (about 300 million in an adult lung) provides a vast surface area for efficient gas exchange. Importance: 🫁 Essential for effective respiration. 🫁 Helps maintain proper oxygen and carbon dioxide levels in the blood. Grab your free download: 77 Must-Know Nursing Topics for the NCLEX!
