Final answer:
Hemorrhoids are indeed the enlargement of veins in the rectal area.
Step-by-step explanation:
True. Hemorrhoids are the enlargement of veins, either internally or externally, in the rectal area. This condition is caused by the weakening of the vein walls or improper blood flow, leading to the swelling and protrusion of the veins. Hemorrhoids are commonly found in the lower rectum or anus and can cause discomfort, pain, and bleeding.
