Answer::Inferior mesenteric artery
· The inferior mesenteric artery is the third unpaired branch of the aorta.
· It is a much smaller calibre vessel compared with the coeliac trunk or superior mesenteric artery.
· It supplies blood to the mid transverse colon through to the proximal rectum.
· Branches of the internal iliac artery supply the middle and distal rectum and anal canal.
· The watershed area is the region of colon between the supply of the superior mesenteric artery and inferior mesenteric artery, and is more vulnerable to ischaemia.
