|The spleen is a wedge-shaped organ lying mainly in the left upper quadrant (left hypochondrium and partly in the epigastrium) and is protected by the left 9thto 11th ribs. It is soft, highly vascular and dark purple in colour. Size and weight vary from person-to-person but on average is around 2.5 cm thick, 7.5cm broad and 12.5 cm in length. The spleen has two poles (superior and inferior), three borders and two surfaces (diaphragmatic and visceral). It is enclosed by a thin capsule, which is easily ruptured.
Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals
