3 wrz 2024 · A primary bronchus divides into secondary bronchi, secondary into segmental bronchi, segmental bronchus into bronchioles which divide into terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
16 mar 2022 · Question. How is food transported in plants? Answer. Phloem transports food materials from the leaves to different parts of the plant body. The transportation of food in phloem is achieved by utilizing energy from ATP. As a result of this, the osmotic pressure in the tissue increases causing water to move into it.
27 mar 2024 · The bronchioles start off as bronchi. The right and left main bronchi branch off from the trachea into the lungs. Subsequently, they further branch into smaller bronchi. Beyond the terminal segmental bronchi, the branches are referred to as bronchioles. The bronchioles can branch between 20-25 times. There are two types of bronchioles:
27 kwi 2017 · Function of the Bronchioles. The bronchioles serve as a transition between the large cartilage supported bronchi that enter the lungs and the tiny alveolar ducts that connect directly to the alveoli.
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole (Figure \(\PageIndex{10}\)), which then leads to an alveolar duct that opens into a cluster of alveoli. Respiratory bronchioles are lined with simple cuboidal epithelium.
Bronchioles open into short segments called terminal bronchioles, which are thin-walled branches of the bronchioles. Terminal bronchioles transition into respiratory bronchioles. Respiratory bronchioles are lined by two types of epithelial cells: ciliated columnar cells and club cells (also known as Clara cells).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole (Figure 22.10), which then leads to an alveolar duct, opening into a cluster of alveoli.
