Respiratory Infection Dog Treatment

A pair of organs situated in the chest, one on each side, the lungsfunction in cooperation with the blood in the oxygen - carbon dioxidetransfer and, to a certain extent, in body temperature control as well.In all mammals a partition strong in some and gossamer thin inothers divides the chest cavity so that the lungs are separated. In thedog this membrane is extremely thin, which means that if the chestcavity is broken open on one side so air enters, not only does the lungon that side collapse but its companion usually follows suit. In humans,where the partition is stronger, if one lung collapses the other may not.From the upper throat a tube called the trachea, made up of manyrings of tough cartilage, runs down into the chest and branches intotwo bronchial tubes, one for each lung. (Bronchitis is an inflammationin the linings of these tubes.) They in turn branch and subdivide intobronchioles and finally into air sacs, each of which is surrounded by anetwork of blood capillaries so thin that gases can be absorbed or es - cape through them.
