Describe how the septum affects blood flow through the heart. - OCR - GCSE Physical Education - Question 5 - 2020 - Paper 1

The septum is a muscular wall that divides the left and right sides of the heart. By maintaining this separation, the septum ensures that oxygenated blood does not mix with deoxygenated blood, allowing each side of the heart to function efficiently.

This separation is crucial for the effective functioning of the heart and maintaining proper blood circulation throughout the body. The left side of the heart pumps oxygen-rich blood to the body, while the right side pumps deoxygenated blood to the lungs for oxygenation.
