Explanation:
Detailed explanation-1: -(Piles) Hemorrhoids are dilated, twisted blood vessels located in the wall of the lower rectum and anus. The swollen vessels are caused by an increase in pressure. Lumps form inside or outside of the anus, which can cause pain or bleeding.
Detailed explanation-2: -Internal hemorrhoids drain through the superior rectal vein into the portal system. External hemorrhoids drain through the inferior rectal vein into the inferior vena cava. Rich anastomoses exist between these two and the middle rectal vein, connecting the portal and systemic circulations.
