|"A thin layer of cells lining the interior surface of blood vessels and lymphatic vessels is called endothelium. Endothelial cells perform many functions such as barrier function, blot clot formation, formation of new blood vessels and blood pressure regulation through vasoconstriction and vasodilation.
The contraction of the muscular wall of the blood vessels results in narrowing of blood vessels which is called vasoconstriction. It plays a key role to stop internal bleeding and heavy loss of blood. The constriction of blood vessels restricts the blood flow and thus results in retention of body heat. The process of vasoconstriction is essential to maintain mean arterial pressure.
Peer review refers to the work done during the screening of submittedÂ manuscriptsÂ and funding applications. This process encourages authors to meet the acceptedÂ standardsÂ 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."
