Q:

What do the bronchi do?

A:

Bronchi help transport air to and from the lungs; they send oxygen to the lungs and allow carbon dioxide to exit the lungs. The bronchi are a part of the respiratory tract that act as an extension of the windpipe.

At the end of the trachea are a right bronchus and a left bronchus. These bronchi play a major role within the conducting zone of the respiratory system. This zone includes the pharynx and the windpipe, which helps move air in and out of the body. The bronchial tubes travel through the lungs and separate into smaller airways known as bronchioles. In the bronchi, air is transported, but there is not a gas exchange.

  • Q:

    What path does air take when you breathe?

    A:

    Humans inhale air that is rich in oxygen and exhale air that is rich in carbon dioxide. The pathway that air takes in the human body begins with the nose and ends with the alveoli in the lungs.

  • Q:

    What moves air into the lungs?

    A:

    Air is moved into the lungs when the diaphragm and intercostal muscles contract to enlarge the chest cavity. This expansion causes air pressure within the chest cavity to decrease, allowing higher air pressure from outside the body to be drawn in through the nose and mouth, filling the lungs.

  • Q:

    What body parts form the human respiratory system?

    A:

    The human respiratory system consists of the nasal cavity, pharynx, trachea, various divisions of the bronchi and two lungs. Air flows through the nose or the mouth into the pharynx, through the trachea, down the right and left bronchi and then through the smaller bronchioles. When it reaches the end of the smallest bronchioles, the air enters tiny air-filled sacs in the lungs called alveoli.

  • Q:

    What are bronchovascular markings?

    A:

    Bronchovascular markings are the visible markings made by blood vessels supplying nutrients to the bronchi and bronchioles in the lungs. These markings become prominently visible when a person is suffering from an infection or inflammation of the pulmonary or respiratory system. A chest x-ray of the patient can easily reveal the well-defined problem in the blood vessels of the lungs.
