where are the human lungs located in the body Near the backbone on either side of the heart. what distinguishes the right lung from the left lung in humans? The right lung is bigger than the left, which shares space in the chest with the heart. name some tissues which make up that organ. UNANSWERABLE what is the function of this respiratory organ? The major function of the lungs is gas exchange between the lungs and the blood. The alveolar and pulmonary capillary gases equilibrate across the thin blood–air barrier. from where does this organ get its blood supply? The lungs have a dual blood supply provided by a bronchial and a pulmonary circulation. The bronchial circulation supplies oxygenated blood to the airways of the lungs, through the bronchial arteries that leave the aorta. what happens to the organ if there is a deficiency in vitamin a? This can disrupt the normal physiology of the lung and predispose to respiratory diseases. can you tell in a short sentence how is the structure of this respiratory organ in birds? The lungs of birds contain millions of tiny parallel passages called parabronchi. Small sacs called "atria" radiate from the walls of the tiny passages; these, like the alveoli in other lungs, are the site of gas exchange by simple diffusion. and how is the structure in reptiles? The lungs of most reptiles have a single bronchus running down the centre, from which numerous branches reach out to individual pockets throughout the lungs.

Lung [SEP] Invertebrates
Some invertebrates have lung-like structures that serve a similar respiratory purpose as, but are not evolutionarily related to, vertebrate lungs. Some arachnids, such as spiders and scorpions, have structures called book lungs used for atmospheric gas exchange. Some species of spider have four pairs of book lungs but most have two pairs. Scorpions have spiracles on their body for the entrance of air to the book lungs. The coconut crab is terrestrial and uses structures called branchiostegal lungs to breathe air. They cannot swim and would drown in water, yet they possess a rudimentary set of gills. They can breathe on land and hold their breath underwater.
