How Cardio Improves Your Heart and Lungs

~60 min · 15 stations

How Cardio Improves Your Heart and Lungs is a self-paced learning path in Medicine & Health Sciences, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify core components regarding human aerobic capacity; describe basic pathways involving blood flow through organs; explain cellular processes generating energy during sustained movement.
