@ionx.labs: Struggling to remember the adaptations of alveoli? 🫁 Here's has a simple acronym to help you remember: M1NS! 🫁 M – Moisture: Thin film of moisture to dissolve gases 🫁 1 – One cell thick alveolar walls for a short diffusion distance 🫁 N – Network of capillaries to maintain a steep concentration gradient 🫁 S – Small and numerous alveoli to provide a large surface area These adaptations help make gas exchange more efficient in the lungs. Watch as we break down each adaptation and how it helps with gas exchange 👀 Save this for your O-Level Biology revision! #ionxlabs #biology #Science #olevels #sgstudents
