The lungs and the heart never rest, they work together continuously. The tissue of the lungs is divided into the air-carrying bronchi and the alveoli. The inhaled air passes through the trachea into the two main bronchi, which each lead to one of the two lungs.
There they continue to branch out. The air is further distributed in the bronchi. Foreign bodies, dust, spores and pathogens are also caught here. These stick to the viscous mucus that the mucous membrane of the bronchi produces. Horses are creatures of the great outdoors and the wind. Your bronchial tubes are quickly overwhelmed when exposed to dust, especially fungal spores. Mucus-forming and expectorant herbs ensure that more bronchial secretion can be formed, the mucus drains off better or stuck mucus can be coughed up more easily. The lungs can be supported by inhaling essential oils. Essential oils increase the beating frequency of the cilia in the bronchi, which means that dust and foreign bodies are transported out of the bronchi more quickly and gas exchange is improved.
Gas exchange takes place in the mucous membranes of the alveoli, which are heavily supplied with blood: carbon dioxide from the blood is exhaled, oxygen from the breathing air is absorbed into the bloodstream here. If not enough CO2 is exhaled, the horse becomes acidic, which can lead to COB, for example. From this it becomes clear that the unimpeded intake of oxygen and the exhalation of CO2 are essential prerequisites for the performance and vitality of your horse. It is therefore important to avoid exposure to dust and to support the bronchial mucous membranes in their work.
