This animation will show how pneumonia affects
the lungs and how the medicines work which treat it. Click the navigation arrows below
the animation screen to play, pause, rewind or fast-forward the animation. This animation
contains sound. The bronchi are large tubes which are found in the lungs. Air passes through
the trachea and bronchi to the lungs when you breathe. The bronchi branch into narrower
tubes called bronchioles. The smaller tubes are attached to tiny air sacs called alveoli.
In healthy lungs, the bronchi and alveoli expand and relax allowing oxygen to be taken
into the body. Pneumonia is an infection of the lung tissue. This causes the alveoli (air
sacs) and smaller airways in your lungs to become inflamed and fill with fluid. The inflammation
and fluid make it harder to breathe so you may breathe faster or feel breathless. Medicines
such as antibiotics are usually given to treat the infection. They aim to reduce the inflammation
and fluid in the lungs so that you can breathe normally again. This is the end of the animation.
