What does the pulmonary ligament contain?

The inferior pulmonary ligament is a fused triangular-shaped sheet of parietal and visceral pleura that extends from the hilum to the dome of the hemidiaphragm.

What does pulmonary ligament attach to?

It extends downward in a sheet-like manner from the inferior margin of the pulmonary hilus to the diaphragm and loosely attaches the medial surface of the lung to the mediastinum.

What forms the pulmonary ligament?

The root of the lung is covered in front, above, and behind by pleura, and that at its lower border the investing layers come into contact. Here they form a sort of mesenteric fold, the pulmonary ligament, which extends between the lower part of the mediastinal surface of the lung and the pericardium.

What is the inferior pulmonary ligament?

The inferior pulmonary ligament is a double layer of pleura that drapes caudally from the lung root and loosely tethers the medial aspect of the lower lobe of the lung to the mediastinum.

What does the pulmonary ligament contains Mcq?

Explanation: Pulmonary ligament serves to hold the lower part of lungs in position. It contains a thin layer of areolar tissue with a few lymphatics. Explanation: Diaphragmatic pleura is a layer of parietal peritoneum overlaying the thoracic surface of the diaphragm and the lung.

What is the purpose of the Costodiaphragmatic and Costomediastinal recess?

These allow for expansion during forced respiration. The costomediastinal recess is located anteriorly where the costal and mediastinal pleura meet. The costodiaphragmatic recess is the most clinically important, as most fluid collections pool here. The pleural cavity always maintains a negative pressure.

What is the purpose of simple squamous epithelium in the bronchial tree?

The alveolar ducts and alveoli consist primarily of simple squamous epithelium, which permits rapid diffusion of oxygen and carbon dioxide. Exchange of gases between the air in the lungs and the blood in the capillaries occurs across the walls of the alveolar ducts and alveoli.

What is lung recess?

The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, is the posterolateral fringe of the pleural space, a potential space around the lung inside the pleural cavity.

Why is the Costomediastinal recess important?

The costomediastinal recess is a potential space at the border of the mediastinal pleura and the costal pleura. It assists lung expansion during deep inspiration, although its role is not as significant as the costodiaphragmatic recess, which has a greater volume.

What is the importance of simple squamous epithelium in the alveoli of the lungs?

Because rapid diffusion of gases is necessary between the capillaries and the alveoli, a very thin epithelial layer is needed. As a result, alveoli use simple squamous epithelium so that gases can easily diffuses to and from the bloodstream.

Which epithelium tissue is present in respiratory passage?

pseudostratified columnar epithelial tissue
The conducting passageways of the respiratory system (nasal cavity, trachea, bronchi and bronchioles) are lined by pseudostratified columnar epithelial tissue, which is ciliated and which includes mucus-secreting goblet cells.

What is pleurisy chest pain?

Pleurisy (PLOOR-ih-see) is a condition in which the pleura — two large, thin layers of tissue that separate your lungs from your chest wall — becomes inflamed. Also called pleuritis, pleurisy causes sharp chest pain (pleuritic pain) that worsens during breathing.

What is the function of pulmonary ligament?

The lower end of this is sometimes referred to as the inferior pulmonary ligament. At the lower edge of each lung the pleural layers come into contact with each other and terminate in a free curved edge. The pulmonary ligaments serve to hold the lower part of the lungs in position.

What is inferior pulmonary ligament?

The inferior pulmonary ligament is a fused triangular-shaped sheet of parietal and visceral pleura that extends from the hilum to the dome of the hemidiaphragm. It extends from the mediastinum to the medial surface of the lower lobe and is extra-parenchymal to the lung.

Does pulmanary mean lungs?

The word pulmonary means “pertaining to the lungs.” It is derived from the Latin root word pulmo, which means lung. If someone has pulmonary disease, this means they have a lung disease, and that may affect their ability to breathe well.

Is it pulmonary embolism?

Pulmonary embolism is a blockage in one of the pulmonary arteries in your lungs. In most cases, pulmonary embolism is caused by blood clots that travel to the lungs from the legs or, rarely, other parts of the body (deep vein thrombosis). Because the clots block blood flow to the lungs, pulmonary embolism can be life-threatening.
