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.
IMPACTS OF DROUGHT Drought produces a complex web of impacts that spans many sectors of the economy and reaches well beyond the area experiencing physical drought.This complexity exists because water is integral to society's ability to produce goods and provide services.he types of drought impacts are described below. Economic Impacts Many economic impacts occur in agriculture and related sectors, because of the reliance of these sectors on surface and groundwater supplies.
