Where are bronchioles located?
lungs
Bronchioles are air passages inside the lungs that branch off like tree limbs from the bronchi—the two main air passages into which air flows from the trachea (windpipe) after being inhaled through the nose or mouth. The bronchioles deliver air to tiny sacs called alveoli where oxygen and carbon dioxide are exchanged.
What does the cilia do in the respiratory system?
Tiny hairs called cilia (pronounced: SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
Is bronchi and bronchus the same?
The main bronchi branch into narrower secondary bronchi or lobar bronchi, and these branch into narrower tertiary bronchi or segmental bronchi….

What is Alveol?
(al-VEE-oh-ly) Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
What is the role of the cilia in the nasal cavity?
Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.
What is the main function of cilia in the respiratory system quizlet?
Cilia line the nose and most other airways in the respiratory system. They trap dust and dirt particles and keep them from entering the lungs.
What is a bronchus?
(BRON-kus) A large airway that leads from the trachea (windpipe) to a lung. The plural of bronchus is bronchi. Enlarge. Anatomy of the respiratory system, showing the trachea and both lungs and their lobes and airways.
What is alveolar haemorrhage?
Alveolar hemorrhage is the rarest pulmonary complication of catastrophic antiphospholipid syndrome and is associated with high mortality risk. This life-threatening complication results from autoimmune damage to the alveolar blood vessels.
¿Qué es la cavidad pleural?
La cavidad pleural es el espacio potencial entre las pleuras del saco pleural que rodea cada pulmón. El espacio pleural , saco pleural o espacio interpleural es el espacio potencial entre las dos membranas serosas opuestas ( pleuras ) que recubren cada pulmón (es decir, pleura visceral ) y la pared torácica circundante (es decir, pleura parietal ).
¿Qué son los sacos pleurales?
DESCRIPCIÓN DE LOS SACOS PLEURALES. + +. Cada pulmón (derecho e izquierdo) está encerrado en una membrana serosa llamada el saco pleural ( figura 3-1A ). Los sacos pleurales derecho e izquierdo ocupan casi toda la cavidad torácica, y flanquean ambos lados del corazón. Cada saco pleural está compuesto de dos capas de membrana serosa (secretora),
¿Qué son las pleuras del corazón?
Las pleuras secretan líquido que disminuye la resistencia contra el movimiento de los pulmones durante la respiración. Cada pulmón (derecho e izquierdo) está encerrado en una membrana serosa llamada el saco pleural ( figura 3-1A ). Los sacos pleurales derecho e izquierdo ocupan casi toda la cavidad torácica, y flanquean ambos lados del corazón.
¿Qué son los pulmones 3 caras?
