Slow and steady blood flow is?

Explanation:
The slow and steady blood flow describes venous return. Veins operate at low pressure and are designed to hold and move blood back to the heart with a gentle, continuous flow. Their valves prevent backflow, and the surrounding muscles help push blood upward, creating a smooth, ongoing return rather than the rapid, pulsatile push of arterial flow. Arterial flow is fast and pulsatile because it’s driven by the heart’s contractions, and capillary flow, while slow to allow exchanges of gases and nutrients, isn’t the same musk of steady return to the heart. Lymphatic vessels carry lymph, not blood, so they aren’t the answer here.
