When blood enters a vein from a venule, the blood pressure decreases significantly. Veins have larger diameters and thinner walls compared to arteries, allowing them to accommodate a greater volume of blood at a lower pressure. This transition results in a gradual reduction in pressure as blood flows back toward the heart. Consequently, venous blood pressure is much lower than arterial blood pressure.
