What is the order in which air passes through them during inhalation?

The flow of air from the environment moves through the respiratory system in these sequential steps during inspiration: Nose or mouth > pharynx > larynx > trachea > the right or left bronchi of the lung > bronchioles of the lungs > alveoli of the lungs.

What is the order of how air passes through the body?

Air enters the body through the mouth or nose and quickly moves to the pharynx, or throat. From there, it passes through the larynx, or voice box, and enters the trachea. The trachea is a strong tube that contains rings of cartilage that prevent it from collapsing.

What is the correct order of air flow?

Air enters your body through your nose or mouth. Air then travels down the throat through the larynx and trachea. Air goes into the lungs through tubes called main-stem bronchi.

What is the order of inspiration?

Inspiratory muscles contract (diaphragm descends; rib cage rises). Thoracic cavity volume increases. Lungs are stretched;intrapulmonary volume increases.

How is alveolar air different than inspired air?

a) Alveolar air has a higher PN2 than inspired air. In addition, alveolar air contains a greater amount of carbon dioxide and less oxygen than atmospheric air. This is no surprise, as gas exchange removes oxygen from and adds carbon dioxide to alveolar air.

Which of the following occurs during inspiration?

The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward. When the lungs exhale, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.

How air passes through the respiratory system step by step?

Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx. The entrance to the larynx is covered by a small flap of tissue (epiglottis) that automatically closes during swallowing, thus preventing food or drink from entering the airways.

What is the correct order of air flow from the nose to the alveoli in the lungs?

Air enters through the nose (and sometimes the mouth), moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi and bronchioles till the alveoli.

Which of the following is the correct pathway of air while exhaling?

In order for the lungs to expel air the diaphragm relaxes, which pushes up on the lungs. The air then flows through the trachea then through the larynx and pharynx to the nasal cavity and oral cavity where it is expelled out of the body.

Which statement correctly describes what happens during inspiration?

Which statement correctly describes what happens during inspiration? The external intercostal, pectoralis minor, and sternocleidomastoid muscles contract to expand the rib cage and the diaphragm contracts to flatten its dome shape.

What is the proper sequence of air flow in the human respiratory system?

From front to back the lungs fill the rib cage but are separated by the heart, which lies in between them. The air that we breathe in enters the nose or mouth, flows through the throat (pharynx) and voice box (larynx) and enters the windpipe (trachea). The trachea divides into two hollow tubes called bronchi.

What is the correct sequence of structures through which air passes on the way into the mammalian lung?

In mammals, air is warmed and humidified in the nasal cavity. Air then travels down the pharynx and larynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles.
