The arterial blood supply, position, and length of the appendix were studied 103 Zambian cadavers. In 39.8%, more than one appendicular artery was found. In position, 43.6% were pelvic, and 20.3% retro-cecal. The average length of the appendix was 12.0 cm in males, and 11.4 cm in females. The prevalence of the dual blood supply and pelvic position, may partly explain the recorded rarity of appendicitis among Africans.
对103具赞比亚尸体的阑尾动脉血供、位置和长度进行了研究。发现39.8%的尸体有不止一条阑尾动脉。在位置方面，43.6%位于盆腔，20.3%位于盲肠后。男性阑尾平均长度为12.0厘米，女性为11.4厘米。双重血液供应和盆腔位置的普遍性，可能部分解释了非洲人阑尾炎发病率较低的记录。
