Learn Cardiorespiratory health online -Study heart and lungs biology, at home

Online Course -A Fit Heart and Fit lungs are critical to a person's overall health, wellbeing and longevity.

Cardiovascular disease has become a serious problem in modern society.

Gain an insight and understanding of how your cardiovascular and respiratory systems work together to oxygenate cells and remove carbon dioxide from your body. Understand how the systems are regulated in both resting and active states and learn how different conditions can affect your cardiorespiratory performance. An ideal course for anyone with an introductory knowledge of human biology who is keen to expand their understand of these vital body systems.

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading. During the course students will have practical tasks to perform in their own home, allowing you to experience and investigate the concepts taught in the lessons.
