WebDec 14, 2024 · The term alveolus (singular) refers to a hollow cavity, basin or bowl in latin. Consequently, there are different types of alveoli (plural) found throughout the human body. However, alveoli are most often used to describe the small air sacs of the lungs of mammals, and are therefore known more specifically as the pulmonary alveoli . WebAlso known as the “fight or flight” system, the sympathetic nervous system causes the release of norepinephrine and epinephrine (also known as adrenaline) onto the sinoatrial node (pacemaker) and the ventricular cardiac muscle.
WebJan 17, 2024 · Collapse of the lungs is called alectasis. Fortunately, the type II epithelial cells of the alveoli continually secrete a molecule called surfactant that solves this problem. Surfactant is a lipoprotein molecule that reduces the force of surface tension from water molecules on the lung tissue. WebJun 5, 2024 · Atelectasis is a partial or total collapse of one or both lungs. It occurs when tiny air sacs in the lungs known as alveoli deflate. Bibasilar atelectasis is when the collapse affects the...
WebType II cells in the alveolar wall contain secretory organelles known as lamellar bodies that fuse with the cell membranes and secrete pulmonary surfactant. This surfactant is a film of fatty substances that reduce alveolar surface tension. Continuously released by exocytosis, the coating prevents the alveoli from collapse. WebMar 5, 2024 · The bronchioles end in tiny air sacs called alveoli. Pulmonary Gas Exchange Pulmonary gas exchange is the exchange of gases between inhaled air and the blood. It occurs in the alveoli of the lungs. Alveoli (singular, alveolus) are grape-like clusters surrounded by networks of thin-walled pulmonary capillaries.

It is usually unilateral, affecting part or all of one lung. It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
