Lungs, oxygen transport

Respiration—transport of oxygen from the lungs to the tissues and of COj from the tissues to the lungs Nutrition—transport of absorbed food materials Excretion—transport of metabolic waste to the kidneys, lungs, skin, and intestines for removal Maintenance of the normal acid-base balance in the body... [Pg.581]

Figure 7.8 Comparison of oxygen transport from lung to a cell and then into a mitochondrion with fatty acid transport from an adipocyte to a cell and then into the mitochondria in various tissues/ organs. Fatty add is transported in blood bound to albumin, oxygen is transported in blood bound to haemoglobin. Fatly add is transported within the cell attached to the fatty acid-binding protein (BP), oxygen is transported within a cell attached to myoglobin (Mb). Alb represents albumin, Hb haemoglobin.

Most tissues are constantly dependent on a supply of molecular oxygen (O2) to maintain their oxidative metabolism. Due to its poor solubility, O2 is bound to hemoglobin for transport in the blood (see p. 280). This not only increases the oxygen transport capacity, but also allows regulation of O2 uptake in the lungs and O2 release into tissues. [Pg.282]

Conversely, the role of perfluorocarbons for oxygen transport and in vivo delivery is investigated. In addition to possible use as temporary blood substitute, these fluorocarbon molecules can be applied as respiratory gas carriers, for instance as lung surfactant replacement compositions for neonates and possibly for the treatment of acute respiratory distress syndrome for adults. Another... [Pg.819]

Pulmonary Circulation Transports deoxygenated blood from the right ventricle through the pulmonary artery to the lungs. Oxygenated blood returns through the pulmonary vein to the left atrium. [Pg.287]

The primary function of the erythrocyte is to carry oxygen from the lungs to the peripheral tissues. Its optimal design enables efficient oxygen transport via the hemoglobin molecule. The general metabolic state of the patient and local factors control oxygen release. [Pg.1795]
