Which part of the intestine has a blood supply on both its mesenteric and antimesenteric borders? Ileum Jejunum Transverse colon Duodenum Caecum Please select an option Correct! The majority of the intestines are supplied by blood vessels on their mesenteric border. The ileum is an exception. It receives its blood supply from the antimesenteric border as well from the ileal branch of the ileocaecocolic artery on the mesenteric border. The position of the blood supply (and nerve supply) affects the choice of sites of entry into the intestine during surgery. Most of the intestines receive a unilateral suply so can be opened safely on their antimesenteric border, whereas the ileum with its bilateral supply has to be entered by lateral incision. The antimesenteric vasculature makes the ileum an easily identifiable landmark in surgery. Incorrect. The majority of the intestines are supplied by blood vessels on their mesenteric border.

What is the sequence of blood vessels supplying the kidney? Aorta, renal artery, interlobar artery, interlobular artery, arcuate artery, afferent arteriole, glomerulus. Aorta, renal artery, interlobar artery, interlobular artery, afferent arteriole, glomerulus, interlobular artery. Aorta, renal artery, interlobar artery, arcuate artery, interlobular artery, afferent arteriole, glomerulus. Aorta, internal iliac, renal artery, interlobar artery, arcuate artery, interlobular artery, afferent arteriole, glomerulus. Aorta, renal artery, arcuate artery, interlobar artery, interlobular artery, afferent arteriole, glomerulus. Please select an option Incorrect. Each kidney is supplied by a renal artery, a branch of the abdominal aorta. The renal artery divides into several interlobar arteries. These give rise to arcuate arteries at the corticomedullary junction. These in turn give origin to numerous interlobular arteries that supply the lobules into which the cortex is divided. Each interlobular artery gives rise to many branches (afferent arterioles) that supply individual glomeruli. WikiVet Article: renal blood supply. Incorrect.
