How does the human circulatory system function?

The human circulatory system consists of the heart, blood vessels, and blood. Deoxygenated blood is pumped from the heart to the lungs, where it picks up oxygen and releases carbon dioxide. Oxygenated blood is then carried back to the heart and pumped out to the rest of the body, delivering nutrients and removing waste products. This process is essential for maintaining the body's functions and overall health. In the UK, students in Lower Sixth Form studying Anatomy and Physiology will explore the intricate workings of the human circulatory system in detail.
