pulmonary infiltrate
Emphysema is the irreversible enlargement of the air spaces in the lungs.
The air spaces in the lungs are called pulmonary alveoli. They are where gas exchange occurs in the lungs of mammals.
Mediastinum
Air funnels, or bronchi, split into smaller and smaller spaces within the lungs to increase the surface area available for gas exchange. This branching structure allows for more efficient distribution of air throughout the lungs, ensuring that oxygen can diffuse into the bloodstream and carbon dioxide can be expelled. The progressively smaller airways, culminating in the alveoli, facilitate a large volume of air contact with the blood, optimizing respiratory function.
Empty spaces within the body are commonly referred to as cavities. These include the cranial cavity (housing the brain), thoracic cavity (housing the heart and lungs), and abdominal cavity (housing the digestive organs). These cavities help protect and support the internal organs.
The condition in which fluid fills spaces within the lungs is known as pulmonary edema. This occurs when excess fluid accumulates in the alveoli, the tiny air sacs in the lungs, often due to heart problems, such as congestive heart failure, or other factors like pneumonia or exposure to high altitudes. Symptoms may include shortness of breath, coughing, and a feeling of suffocation. Prompt medical treatment is essential to address the underlying cause and alleviate symptoms.
Alveoli are grape-like air spaces at the distal ends of the bronchial upside-down tree.
The branching tubes within the lungs end at small alveoli.
The actual sites of gas exchange within the lungs are the alvioli.
Alveoli. Singular is alveolus.
Lungs are part of the circulatory system within the human body.
