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 can affect people of all ages, though itâs most common in older children and adults. It causes inflammation and swelling in the trachea and upper bronchial tubes. Bronchitis can be both acute and chronic. Bronchiolitis almost only affects younger children, many under the age of 2.
