The bronchial tubes (or bronchi) are the large tubular structures within the lungs. These carry air into the lungs from the trachea. They branch into smaller tubes called bronchioles, and then to the smallest tubes that contain the alveoli (air sacs) of the lungs.
Capillaries are the small tubes closely attached to the alveoli, or air sacs of the lungs. These capillaries are the site of gas exchange.
The two tubes that carry air from the trachea to the lungs are called bronchial tubesThe bronchial tubes. As these tubes pass through the lungs, they divide into smaller passages called the bronchioles. The bronchioles end in air sacs called alveoli.
The smallest tube in the lungs is the Bronchus
Because the air sacs carry oxygen to the blood!
Alveoli
Alveoli
Tiny tubes in the respiratory system, such as bronchioles and alveolar ducts, are connected to the air sacs, or alveoli. These tubes help in the exchange of gases like oxygen and carbon dioxide between the lungs and blood vessels. The air sacs in the lungs facilitate this gas exchange process by increasing the surface area available for diffusion.
Alveoli are microscopic air sacs branching off the bronchioles in the lungs. They are responsible for the exchange of gases, allowing oxygen to enter the bloodstream and carbon dioxide to be removed from the body. This process is essential for respiration and maintaining life.
