Lactiferous Duct
Lactiferous Duct
Respiratory bronchioles, alveolar ducts, and alveoli.
alveolar ducts
This process involves a system of ducts and glands that transport the milk from the mammary glands to the nipple. The milk is produced in the alveoli, then moves through the ducts to reach the nipple for feeding. The release of milk is triggered by oxytocin, which causes the muscle cells around the alveoli to contract and push the milk out.
The respiratory zone of the tracheobronchial tree includes the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli where gas exchange occurs. This is where oxygen is absorbed into the bloodstream and carbon dioxide is released from the bloodstream.
Technically yes. However, there are a few more strucutres that thanks to their histological properties can participate in the gas exchange process: respiratory bronchioles, and alveolar ducts.
The alveoli are attached to the respiratory tree at the terminal bronchioles, which are the smallest branches of the bronchi. From the bronchioles, air passes into the alveolar ducts and then into the alveolar sacs, where the alveoli are clustered. This structure allows for efficient gas exchange between the air in the alveoli and the blood in the surrounding capillaries.
The development of alveoli in the breast allows for the production of breast milk. Alveoli are small sacs where milk is produced by specialized cells. When a baby suckles, it triggers the release of hormones that signal the alveoli to release milk into the ducts, which then flows out of the nipple for the baby to feed on.
The bronchi branch into smaller tubes called bronchioles, which then lead to clusters of air sacs called alveoli. The alveoli are the site where oxygen and carbon dioxide exchange occurs during the process of respiration.
Flexible air ducts in the ECU are typically stored in the ceiling cavity or in a dedicated storage compartment within the unit when not in use. This helps to maintain a tidy and organized appearance while also protecting the ducts from damage.
An alveolus (plural: alveoli, from Latin alveolus, "little cavity") is an anatomical structure that has the form of a hollow cavity. Found in the lung parenchyma, the pulmonary alveoli are the dead ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, which are both sites of gas exchange with the blood as well.
No, the alveolar ducts are not part of the conducting zone. They are part of the respiratory zone, which includes structures involved in gas exchange. The conducting zone consists of the airways that filter, warm, and humidify the air, including the nasal passages, trachea, and bronchi, leading up to the terminal bronchioles. Alveolar ducts and alveoli are where oxygen and carbon dioxide exchange occurs.
