function properly, a proper pH level of the blood must be maintained at 7.4. Buffers refer to a solution containing a mixture of weak acids and salts of their corresponding bases. The optimum value of the pH is maintained by buffer system made up of three types. The buffer maintains the blood pH by adjusting the pH level, that is, increasing the acidity if the pH rises above the optimum value of 7.4 or taking up the hydrogen ions when the pH of the blood lowers below the optimum value. In this context, we will discuss the intracellular and plasma buffer system and how it function. Bicarbonate buffer system is the predominant buffer system that operates in the blood plasma. In essence, this buffer...

function. According to the Glossary of Periodontal terms, guided tissue regeneration refers to procedures that try to regenerate damaged periodontal structures through the response of differential tissues. On the other hand, bone replacement grafts procedures aid in periodontal regeneration and bone formation. This paper focuses on the goals of the two periodontal therapy procedures; bone replacement grafts and guided tissue regeneration. It also gives brief explanations how these goals are achieved; that is the various mechanisms. Finally, the paper looks at how and when the two procedures are used together. Goal of Bone Replacement Grafts and Guided Tissue Regeneration Goal of Bone Replacement...

functioning issues concerning the "Change of Mind" documentary and "Sing Unburied" novel. Effects of Brain Injury on Society Brain injury not only subject victims to sufferings but also the entire society is adversely affected. The condition deprives the society productive human resources and also leads to the society incurring financial costs. Victims suffer mood swings and losses concentration which makes them lose their jobs (Pyror, 2016). Consequently, such individuals may engage in criminal activities to earn a living hence incurring financial problems to the society. What interventions could be helpful to this population in determining Brain Injury? The society has a role to play in...
