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.
Effects of reduced tidal volume ventilation on pulmonary function in mice before and after acute lung injury. Thammanomai A, Majumdar A, Bartolak-BartolÃ¡k Suki, E Suki. B. dept Of Biomedical, Engineering Boston., Univ, BOSTON ma, 02215. usae investigated the influence of load impedance on ventilator performance and the resulting effects of reduced tidal volume (Vt) on lung physiology during a 30-min ventilation of normal mice and 10 min of additional ventilation following lavage-induced injury at two positive end-expiratory pressure (PEEP) levels.
