     • One bronchus enters each lung. Each bronchus branches out into smaller tubes called bronchioles. Air travels through these bronchioles. At the end of the bronchioles, the air enters one of the many millions of alveoli where gaseous exchange takes place.

   How do bronchial tubes pass through the lungs?

   • As the bronchial tubes pass through your lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has about 600 million alveoli. The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from inhaled air passes into your blood.

   How do bronchial tubes work?

   • Your bronchial tubes are lined with CILIA (like very small hairs) that move like waves. This motion carries MUCUS (sticky phlegm or liquid) upward and out into your throat, where it is either coughed up or swallowed. Mucus catches and holds much of the dust, germs, and other unwanted matter that has invaded your lungs.

   Where does blood travel from bronchial tubes to lungs?

   • From there, it travels down bronchial tubes that enter the lungs. At the smallest end of the bronchial tubes (bronchioles) are alveoli — millions of tiny air sacs that are each covered by thin blood vessels called capillaries. The junction of alveoli and capillaries is called alveo-capillary bed.

   Mar 24, 2022 · Air first enters your body through your nose or mouth, which moistens and warms the air since cold, dry air can irritate your lungs. The air then travels past your voice box and down your windpipe. Rings of tough tissue, called cartilage, acts as a support to keep the bronchial tubes open.

   Air travels through the trachea before it reaches the lungs. The trachea can also be referred to as the windpipe. It attaches to the cartilage located in your throat, from where it then travels downward before it breaks off into two primary bronchi.

   The TRACHEA (windpipe) is the passage leading from your pharynx to the lungs. The RIBS are bones supporting and protecting your chest cavity. They move a small amount and help the lungs to expand and contract. The trachea divides into the two main BRONCHI (tubes), one for each lung.

   When you breathe out, air with carbon dioxide leaves your lungs through your bronchial tubes, up through the trachea and larynx and out through your mouth or nose. The heart and lungs work in harmony in this process to circulate oxygen to muscles, vital organs and all cells so that they can properly function.

    Oct 24, 2023 · The bronchi are the two large tubes that carry air from the windpipe into the lungs and back out again. A crucial part of the respiratory system, the bronchi function primarily as passageways for air, bringing oxygen into the lungs and expelling carbon dioxide.

    Sep 29, 2023 · The WINDPIPE (trachea) is the passage leading from your throat to your lungs. The windpipe divides into the two main BRONCHIAL TUBES, one for each lung, which divides again into each lobe of your lungs. These, in turn, split further into bronchioles.
