30 paź 2023 · Smooth muscle is a type of tissue found in the walls of hollow organs, such as the intestines, uterus and stomach. You can also find smooth muscle in the walls of passageways, including arteries and veins of the cardiovascular system.
30 paź 2023 · 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.
The wall of each bronchiole has a layer of smooth muscle that can contract to narrow the airway. Distally are the smallest bronchioles called terminal bronchioles, which give rise to the respiratory bronchioles that end up with alveolar ducts.
The respiratory bronchioles lead into alveolar ducts, (which are surrounded by smooth muscle, elastin and collagen), which lead into the alveolar sacs. These have several alveoli, surrounded by blood vessels - from the pulmonary system.
6 sie 2015 · Alveoli are the basic unit of the gas exchange surface. In summary, the following things can be said about the alveolar shape and structure: Largely polyhedral shape. Open at one end, like a cup. Walls of the alveoli are composed of the pulmonary capillary sheet.
An alveolar duct is a tube composed of smooth muscle and connective tissue, which opens into a cluster of alveoli. An alveolus is one of the many small, grape-like sacs that are attached to the alveolar ducts.
