Which of the following is NOT an end aery:

Splenic aery itself is not an end aery - splenic branches of splenic aery are end aeries. Splenic branches do not have an anastomosis once they enter the substance of spleen. Splenic aery branches to stomach and pancreas, do anastomose within the substance of the respective organ (not end aeries). An end aery (or terminal aery) is the only supply of oxygenated blood to a specific poion of tissue. It does not anastomose with the neighbors aeries. There is no collateral circulation present besides the end aeries. Any block leads to iscahemia and infarction. Note: Functional end aeries have anatomical anastomosis existing but is incapable of providing a sufficient supply of blood (Ineffectual anastomoses). Functional end aeries supply segments of the brain, liver, kidneys, spleen and intestines; they may also exist in the hea.
