The spongy mass of the lungs is made up primarily of elastic connective and the right lung is larger and has three lobes, while the left is smaller and has only two because of the presence of the heart. The space left from the lungs to the heart is called mediastinum, the lungs are covered by pleura, a serous membrane double wall with a thin layer of liquid between.
The lungs are perfused from a lot of blood and blood vessels enter and leave through the hilum. There are trophic and functional vessels. The vessels are trophic artery and vein bronchial asthma (bronchial artery is a branch of the aorta), the pots are functional pulmonary artery and vein that are the lesser circulation: the pulmonary vein arterial port el ' artery venous blood as opposed to what happens in heavy traffic.
It is incorrect to call

It is incorrect to call
- arteries vessels from the heart, veins
- those who come to the heart regardless of the type of blood they contain.
The pulmonary artery from the heart reaches the lungs with blood and venous branches around the alveoli in a dense capillary network.
