What is the path air must take to reach the alveoli?

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.

What is the correct pathway of air during inspiration?

During inspiration, fresh air enters the respiratory system through the pared external nares (nostrils; shown here) and/or the oral cavity to the pharynx. Air then travels through the glottis into the trachea, through the bronchi and bronchioles to reach the alveoli.

Which of the following is the correct sequence of the pathway through which air travels after entering the body?

The correct sequence is Pharynx → Larynx → Trachea → Bronchioles. The pharynx opens outside through the nostrils.

What are air sacs?

air sac, any of the air-filled extensions of the breathing apparatus of many animals. Air sacs are found as tiny sacs off the larger breathing tubes (tracheae) of insects, as extensions of the lungs in birds, and as end organs in the lungs of certain other vertebrates.

What pathway does air follow after it enters the nose and mouth?

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 pathway of air?

Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

What pathway does air travel through the respiratory system quizlet?

The path of air through the respiratory tract is: trachea, bronchi, bronchioles, alveoli. It is important to note that no gas exchange takes place in the bronchi, but does in the bronchioles, which are passageways that branch off from the main bronchi and eventually lead to alveolar ducts.

Which of the following will be the path of air during exhalation?

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.

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

LIST IN ORDER, THE RESPIRATORY STRUCTURES THAT AIR PASSES THROUGH DURING INSPIRATION. NOSTRIL-> NASAL CONCHAE ->PHARYNX->EPIGLOTTIS->LARYNX->TRACHEA->PRIMARY BRONCHI->SECONDARY BRONCHI->TERTIARY BRONCHI->TERMINAL BRONCHIOLES->RESPIRATORY BRONCHIOLES->ALVEOLAR DUCTS->ALVEOLAR SACS.

What is the path taken by air molecules as they travel from terminal bronchioles to alveoli?

What is path taken by air molecules into and through bronchial tree? What is the path taken by air molecules as they travel from terminal bronchioles to alveoli? terminal bronchioles> respiratory bronchioles> alveolar ducts> alveoli. What is main muscle that powers your breathing?

What happens to the oxygen that enters the alveoli?

In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls. Once in the bloodstream, oxygen gets picked up by the hemoglobin in red blood cells. Blood rich in carbon dioxide then returns to the heart via the veins.
