Tissue samples have been taken from the smooth membrane around your lungs.

When we breathe, the air gets into the body via the respiratory tract. The respiratory tract can be divided into the upper and the lower respiratory tracts. The nose and throat form part of the respiratory tract. The lower respiratory tract begins at the larynx in the throat. It includes the windpipe and the bronchia. You need lungs to breath. When we breathe in, oxygen enters the lungs and accumulates in the blood. This blood then flows to the heart. The heart then pumps the oxygen-rich blood throughout the body. All of the organs are supplied with oxygen as a result.

The smooth membrane around your lungs and the diaphragm, for example, are also part of the respiratory organs. The lungs are surrounded by a smooth membrane. A smooth membrane like this is also located inside the ribs. Both membranes cling to each other via a small amount of fluid.

A needle was used to take the tissue samples from you. This needle was inserted through your skin into the smooth membrane around your lungs. At the same time, pictures were taken of the inside of your body. That way it is possible to see exactly where the needle is.
