Variation does not only occur in the structure of individual flowers, but also their arrangement. Some flowers are solitary while others are clustered. The arrangement of flowers on a flower stalk is called the âinflorescence typeâ.
Bronchitis is an infection or inflammation of the large air passages to the lungs. (These airways are called bronchi.) When your child has a cold, sore throat, flu, or sinus infection, the virus that caused it can spread to the bronchi. Once the germs take hold there, the airways become swollen, inflamed, and partly blocked with mucus.
Bronchitis is an inflammation of the airways in the lungs. The main tubes that air flows through in the lungs are called bronchi, and branching off them are smaller tubes called bronchioles. When these tubes become inflamed it causes narrowing, constriction, and blockage of the airways, which leads to symptoms of bronchitis.
