"Alveoli" Natural Recordings by Native Speakers
Alveoli are small air sacs in the lungs where gas exchange occurs between the air we breathe and the bloodstream. Oxygen enters the blood, and carbon dioxide leaves the blood to be exhaled.
1. The alveoli are tiny air sacs in the lungs where gas exchange occurs between the air and the bloodstream.
2. Smoking can damage the alveoli, reducing their ability to effectively transfer oxygen into the body.
3. During deep breathing, the diaphragm contracts, expanding the alveoli and increasing the amount of air that can be exchanged.
4. In pneumonia, inflammation in the alveoli can fill them with fluid, impairing respiratory function.
5. Pulmonary fibrosis is a condition characterized by the scarring of alveoli, leading to reduced oxygenation and breathing difficulties.
Alveolata is a taxonomic group of single-celled eukaryotes, also known as alveolates. They are characterized by the presence of tiny, saclike structures called alveoli under their cell membrane. These alveoli give the organism a泡状 appearance and help with locomotion, feeding, and gas exchange. The Alveolata includes diverse organisms such as ciliates (like Paramecium), dinoflagellates, and apicomplexans (which include parasites like Plasmodium, the causative agent of malaria).
Alveolate refers to something that has small, hollow, or chambered structures resembling alveoli, which are tiny air sacs found in the lungs. It can be used to describe organisms or tissues with a similar architecture, such as the alveolate cells in certain plants or the alveolate margins of some leaves where small air pockets are present.
"Alveolated" refers to something that is divided or structured like alveoli. Alveoli are tiny air sacs in the lungs where gas exchange occurs. So, if something is alveolated, it has multiple small compartments or chambers resembling these air sacs.
Alveolates are a group of eukaryotic organisms characterized by having alveoli, which are saclike structures or compartments within their cells. These alveoli provide support and help with various cellular functions, such as oxygen exchange in certain protists and unicellular organisms like dinoflagellates, ciliates, and apicomplexan parasites (like Plasmodium, which causes malaria).
Alveolation refers to the presence of small air sacs called alveoli in the lungs, where gas exchange occurs between the air and the bloodstream. It is a key feature of mammalian respiratory systems.
"Alveole" refers to a small air sac in the lungs where gas exchange occurs between the air and the bloodstream. In human anatomy, alveoli are crucial components of the respiratory system, facilitating oxygen intake and carbon dioxide removal.
Alveolectomy is a surgical procedure in which part or all of the alveoli, which are the small air sacs in the lungs where gas exchange occurs, are removed. This is typically done to treat certain lung conditions, such as emphysema or bullous lung disease, to improve breathing function or to prevent complications.
Alveoles are tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged between the air and the bloodstream during respiration. They are the primary units of gas exchange in the human respiratory system.
