3. The lymphatic system also relies on unidirectional movement to return interstitial fluid to the bloodstream.
4. Arterial blood moves away from the heart while venous blood returns unidirectionally to the heart.
5. Disruptions in unidirectional flow can lead to medical conditions such as varicose veins or heart valve disorders.
