CIRCULATORY SYSTEM. The cardiovascular, or circulatory, system in humans is composed of the heart and the blood. vessels--arteries, veins, and capillaries. Its purpose is to provide nutrients and oxygen to the tissues and to remove wastes from them. It is also where the body fights infections.
The respiratory quotient (or RQ or respiratory coefficient), is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production.Such measurements, like measurements of oxygen uptake, are forms of indirect calorimetry.It is measured using Ganong's Respirometer.Q as measured includes a contribution from the energy produced from protein. However, due to the complexity of the various ways in which different amino acids can be metabolized, no single RQ can be assigned to the oxidation of protein in the diet.
So far, mostly quantitative meta-analyses focusing on the impact of continuity of care and reviews of qualitative and quantitative studies have been carried out. Qualitative investigation has an important role in evidence-based medicine, in that it represents the human dimensions and experiences of healthcare users.
