There are anal cushions located in the upper anal canal at three different sites. The anal cushions contain connections between the rectal arteries and the veins, which are very vascular and supported by smooth muscle and connective tissue. Along with internal and external sphincters, they help to control the anal continent. Sometimes, due to specific reasons, these blood vessels get swollen and enlarged and form Hemorrhoids. There are two types of hemorrhoids, internal and external hemorrhoids are defined by the location relative to the dentate line. Hemorrhoids above the dentate line are known as internal hemorrhoids, and if the hemorrhoids are below the dentate line known as external hemorrhoids. 3dmedicalanimation copyrighted_by_Dandelion _Team Fertilization medical animation we all won this race!
