Book Lungs For Respiration Are Found In
Book lungs one of the two kinds of respiratory organ compare tracheal spiracles found in spiders.
Book lungs for respiration are found in. Carbon dioxide produced by cellular respiration is in turn released through exhalation. The four pairs of book lungs are located in the third fourth fifth and sixth mesosomal segments. Then oxygen passes through the blood of the spider as it circulates in the lung.
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. They are located in the abdomen just below the pedicel and are composed of many fine leaves. Blood is passed over a large surface area to absorb oxygen.
The lungs are also closely associated with the cardiovascular system as they are the sites for gas exchange between the air and the blood. The book lungs are in the cavities of the abdomen. Thus the spider can breathe and carry out everyday functions.
Book lung form of respiratory organ found in certain air breathing arachnid arthropods scorpions and some spiders. Each book lung consists of a series of thin plates that are highly vascular i e richly supplied with blood and are arranged in relation to each other like the pages of a book. Each book lung consists of an air cavity or atrial chamber on the ventral side which opens to the outer side by a slit like spiracle or stigmata that opens on the ventro lateral side of the sternum.
Through a small slit the air enters the cavities.
