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.
If the SD is over 0.25, the RQ value is considered unreliable. RQ = Relative quantification = 2 - ââCt The RQ is your fold change compared to the calibrator (untreated sample, time zero, etc.). The calibrator has a RQ value of 1. All samples are compared to the calibrator.
