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.
What is the correct sequence of structures through which air passes through?
The respiratory route of air in the respiratory tract is:
Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi → Bronchioles → Alveoli or air sacs
. Therefore, out of the given options, option D ‘Nostrils —> pharynx —> larynx —> trachea —> alveoli’ is the most appropriate option.
What is the order of structures air passes through on its way to the alveoli?
On its way to the alveoli of the lungs air travels through
the nasal cavity, pharynx, larynx, trachea, bronchi and bronchioles
.
What is the correct order in which air flows through the respiratory tract?
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 order of airflow from the nose to the alveoli?
The respiratory route air passes through is:
Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi
(with cartilaginous rings) →Bronchioles (without rings) → Alveoli (air sacs).
Which of the following is the correct order of respiratory structures?
Windpipe (
trachea
) Large airways (bronchi) Small airways (bronchioles) Lungs.
Which of the following describes a correct order of structures in the respiratory passageways group of answer choices?
Assuming air comes in through the nose, the correct order is: …
Both air to the lungs, and food to the gut, pass through the pharynx
; the epiglottis, a flap of tissue, helps keep food and water from entering the lungs. Larynx (voice box).
What is the pathway of air into the lungs?
When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into
your trachea (windpipe)
. Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.
What is the correct order in which air flows through the respiratory tract quizlet?
air enters the body thru the nose,
pharynx (throat), larynx (voice box)
, trachea (windpipe), bronchi, bronchioles, the lungs, and eventually the alveoli.
What is the proper term for breathing?
Breathing (or
ventilation
) is the process of moving air out and in the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. … Breathing, or “external respiration”, brings air into the lungs where gas exchange takes place in the alveoli through diffusion.
What is the pathway taken by air in the respiratory system illustrate with a Labelled diagram?
Air
enters the nostrils passes through the nasopharynx
, the oral pharynx through the glottis into the trachea into the right and left bronchi, which branches and rebranches into bronchioles, each of which terminates in a cluster of alveoli Only in the alveoli does actual gas exchange takes place.
What are the 8 structures and organs of the respiratory system?
These include
the nose, pharynx, larynx, trachea, bronchi and lungs
. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.
What are the parts of the respiratory system and their functions?
Pharynx (throat): Tube that delivers air from your mouth and nose to the
trachea
(windpipe). Trachea: Passage connecting your throat and lungs. Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung. Lungs: Two organs that remove oxygen from the air and pass it into your blood.
What structures are used by both the respiratory and digestive systems?
The pharynx
, commonly called the throat, is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.
How do you describe the pathway of oxygen in the breathing system?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below,
inhaled oxygen moves from the alveoli to the blood in the capillaries
, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
How does the respiratory system work in order?
The respiratory system includes
the nose, mouth, throat, voice box, windpipe, and lungs
. Air enters the respiratory system through the nose or the mouth. … The trachea, or windpipe, is the continuation of the airway below the larynx.
