The human body is an amalgamation of specialised and complex systems. Normal, healthy body functions rely on a symphony of these systems, dynamically working in concert to keep us in a stable homeostatic state.

This course begins by examining the unconscious regulation of body systems by the autonomic nervous system, helping us respond when homeostasis is challenged.

We then explore the cardiovascular and respiratory systems in depth, providing an integrative perspective. We investigate the contractility of the heart, how the circulatory system distributes blood to tissues and organs, the key roles of the respiratory system in gas exchange and maintaining acid-base equilibrium, and the importance of the lymphatic system in maintaining fluid balance. The course aims to provide you with an appreciation of how homeostasis is regulated by close interactions between these body systems.

This interactive course incorporates videos, insights from experts in human physiology, and assessment to test your new understanding of systems physiology.

Career center

Learners who complete Cardiovascular & Respiratory Systems will develop knowledge and skills that may be useful to these careers:
Medicine
Physicians, including doctors and surgeons, use their knowledge of human physiology, anatomy, and pharmacology to prevent and treat diseases. Doctors rely upon coursework in cardiovascular and respiratory systems to understand the functioning of the heart, vascular system, lungs, and lymphatic system, and to make diagnoses and develop treatment plans for patients with medical conditions including heart failure, hypertension, stroke, and pulmonary embolism.
Nursing
Nurses use their knowledge of human physiology and medicine to administer patient care, and are often the first point of contact between a person and the medical system. An understanding of normal and abnormal physiology, such as the function of the cardiovascular and respiratory systems, is essential to the work of nurses.
Physician Assistant
Physician assistants provide patient care under the supervision of a physician, and in many states can practice independently. A solid understanding of cardiovascular and respiratory physiology is crucial to treating patients, making diagnoses, and administering care.
Athletic Trainer
Athletic trainers may need to understand the cardiovascular and respiratory systems to evaluate and treat injuries within the body.
Physiologist
Physiologists study the function of the human body, including the cardiovascular and respiratory systems, often in the context of health and disease. This course will help a physiologist understand the heart's function, circulatory flow, gas exchange, and acid-base equilibrium.
