A book lung is a type of respiration organ used for atmospheric gas exchange that is present in many arachnids such as scorpions and spiders each of these organs is located inside an open ventral abdominal air filled cavity atrium and connects with the surroundings through a small opening for the purpose of respiration. In the breathing process the lungs take in oxygen from the air through inhalation.

In the primitive spiders such as the mesothelae there are two pairs of book lungs. Spiracle in arthropods the small external opening of a trachea respiratory tube or a book lung breathing organ with thin folds of membrane resembling book leaves. Spiracles are usually found on certain thoracic and abdominal segments.

Respiratory openings on the abdomen called spiracles lead to the so called book lungs named for their layered structure or a system of tubes tracheae for carrying air or both. The lungs are also closely associated with the cardiovascular system as they are the sites for gas exchange between the air and the blood.
