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.
What Is Chronic Bronchitis? Bronchitis is an inflammation of the bronchial tubes (airways), which bring air to and from your lungs. When the bronchial tubes are inflamed, the lining, or mucous membrane, of the airways swells and grows thicker. It also produces an excess amount of mucus. The narrowing and increased blockage of the bronchial tubes from the mucus causes airflow to decrease and a phlegmy cough to develop.
