What is lung basal?

Basal cells are an important stem cell lineage in many tissues, including the lung. In this issue of Developmental Cell, Yang et. al. (2018) find that basal cells emerge very early in lung development and that a subset of these contributes to the expansive epithelial wound response observed after influenza injury.

What causes basal atelectasis?

Atelectasis occurs from a blocked airway (obstructive) or pressure from outside the lung (nonobstructive). General anesthesia is a common cause of atelectasis. It changes your regular pattern of breathing and affects the exchange of lung gases, which can cause the air sacs (alveoli) to deflate.

What is basal atelectasis?

The collapse of basally oriented lung tissue, a common post-operative complication, which is associated with mucus retention due to poor pulmonary clearance, and secondary infection. Clinical findings.

What are the 3 types of atelectasis?

The term atelectasis can also be used to describe the collapse of a previously inflated lung, either partially or fully, because of specific respiratory disorders. There are three major types of atelectasis: adhesive, compressive, and obstructive.

What are basal changes in the lungs?

Basal cells reside in the airway epithelium from the trachea and, in diminishing numbers, down to the respiratory bronchioles. They are candidate stem cells in the conducting airways, responsible for normal cell replacement and epithelial remodeling upon lung injury.

What is the function of basal cells?

Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin’s surface, where the old cells die and are sloughed off.

What is basilar atelectasis of the lung?

Bibasilar atelectasis is a condition that happens when you have a partial collapse of your lungs. This type of collapse is caused when the small air sacs in your lungs deflate. These small air sacs are called alveoli. Bibasilar atelectasis specifically refers to the collapse of the lower sections of your lungs.

Where are the basal cells located?

A small, round cell found in the lower part (or base) of the epidermis, the outer layer of the skin. Anatomy of the skin showing the epidermis (including the squamous cell and basal cell layers), dermis, subcutaneous tissue, and other parts of the skin.

What do basal cells do in the respiratory system?

Basal cells provide an attachment site for ciliated and goblet cells to the basal lamina. They also respond to injury and act in oxidant defense of the airway epithelium and transepithelial water movement. Within the hundreds of millions of microscopic alveolar sacs, the exchange of oxygen for carbon dioxide occurs.
