Bird Lungs
Unlike reptiles, birds are homeothermic ("warm blooded"), maintaining a constant body temperature (usually around 40°C) despite wide fluctuations in the temperature of their surroundings.
The Lungs
(Pulmones)
The lungs are the essential organs of respiration; they are two in number, placed one on either side within the thorax, and separated from each other by the heart and other contents of the mediastinum (Fig. 970).
Lungs
Lungs are ingrowths of the body wall and connect to the outside by as series of tubes and small openings. Lung breathing probably evolved about 400 million years ago.
lungs Sac-like structures of varying complexity where blood and air exchange oxygen and carbon dioxide; connected to the outside by a series of tubes and a small opening.

The invaginated respiratory surfaces of terrestrial vertebrates, land snails, and spiders that connect to the atmosphere by narrow tubes.

Marfan syndrome is a risk factor for spontaneous pneumothorax. In spontaneous unilateral pneumothorax, air escapes from a lung and occupies the pleural space between the chest wall and a lung.
As your lungs expand, they fill with air. If you were to again squeeze the bottle what would happen? The water would squirt out, wouldn'tS it. When your diaphragm again squeezes you’re the bottom side of your lungs, air is forced out of them.
The internal lungs of vertebrates evolved from the air bladder of fishes who at first used it for buoyancy. (This air sac was derived from endoderm of the intestinal tract.). The most primitive lung is found in the amphibians.
In mammalian lungs, a process of diffusion takes place in the aveoli: due to differences in partial pressures across the alveolar-capillary membrane, oxygen diffuses into the blood and carbon dioxide diffuses out.
Facilitated diffusion ...
Cystic fibrosis -- an autosomal recessive genetic condition of the exocrine glands, which causes the body to produce excessively thick, sticky mucus that clogs the lungs and pancreas, interfering with breathing and digestion.
CBD is an autoimmune disease affecting the lungs of susceptible individuals. Antigen-presenting cell surface proteins have been the focus of investigation into possible genetic susceptibility to this disease.
Cystic fibrosis of the pancreas was the original description of this disease because it affects the pancreas and the lungs, although it's the lungs that are the cause of the most major concerns these days.
breathing, which is the process of inhaling and exhaling gases from and into the external environment - a function of the lungs and other structures with similar function (e.g. gills) ...
This problem set is designed to help you understand the basic anatomy and physiology of the respiratory organs, primarily the lungs. You will learn about lung development, respiratory toxicology, secondhand tobacco smoke, asthma, and lung cancer.
Fish have gills while mammals, birds, and reptiles have lungs. Your respiratory system is made of your nose and mouth, a tube called the pharynx, another tube called the trachea, and your lungs.
Endoscopy allows a physician to insert a lighted instrument to look for tumors in organs such as the stomach, colon, and lungs.
Vertebrates with lungs have a single trachea carrying air to the lungs, while insects and some other land-living arthropods have a complex network of tracheae carrying air from the spiracles to all parts of the body.
The respiratory tract in humans is lined with cilia that keep inhaled dust, smog, and potentially harmful microorganisms from entering the lungs.
Alveolus the tiny air sacs in the lungs in which gases are exchanged with the blood

Thick mucous forms in the digestive tract and lungs of people with CF. As a result, they have difficult breathing and are susceptible to lung infections.
People with cystic fibrosis have a life expectancy of approximately 30 years.
In vertebrates, that portion of the trunk containing visceral organs except for heart and lungs; in arthropods, ...
Main airway that runs from the base of the throat down to the lungs. Divides into the two main bronchi (right and left) that supply each lung with air.

pulmonary circuit The system of blood vessels from the right ventricle of the heart to the lungs, transporting deoxygenated blood and returning oxygenated blood from the lungs to the left atrium of the heart.
In mammals the paired lungs are each supplied by a bronchus that divides, treelike, into bronchioles. Each bronchiole ends in an atrium from which arise numerous alveoli that contact a vast capillary system.
For example, the glycoprotein hormone alpha subunit is produced only in certain cell types of the anterior pituitary and placenta, not in lungs or skin; thus expression of the glycoprotein hormone alpha-chain gene is said to be tissue-specific.
In vertebrates, this innermost layer of cells goes on to form the linings of the gut (esophagus, stomach, intestines, rectum, colon), pharyngeal pouch derivatives (tonsils,thyroid, thymus, parathyroid glands), lungs, liver, gall bladder, pancreas.
Coursing through the capillaries you find blood plasma transporting nutrients to the tissue and removing waste. Red cells slip by single file releasing their load of oxygen and picking up carbon dioxide for return to the lungs.
