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 a respiratory disease in which the mucus membrane in the lungs' bronchial passages becomes inflamed. As the irritated membrane swells and grows thicker, it narrows or shuts off the tiny airways in the lungs, resulting in coughing spells that may be accompanied by phlegm and breathlessness.
