Document Summary
In asthma, if they have a bronchospasm, that can be reversed. A normal lung has defined and small airways. In copd, you can see the destruction within the airways and a lot of mucus production. Whatever surface area is left is clogged with mucus. Irreversible, might get some relief in terms of bronchoconstriction, but the damage is irreversible. Glucocorticosteroids inhibit inflammation and are effective in treatment. Short acting beta2 agonists for acute symptoms. Lecture 21: gastrointestinal drugs - h2 antagonists and ppis. Gastric acid secretion is a complex and dynamic process, regulated by neural, paracrine and hormonal pathways, as well as mechanical mechanisms. The enteric ns is called the second brain . Embedded in the lining of the gi system. Governs the function of the gi tract, but relies on innervation from the vagus nerve (autonomic ns). When you see or smell food, this is perceived in the brain and stimulates the vagus nerve.
