Exam 26: Anatomy of the Respiratory System

The bronchi,bronchioles,and alveoli all function as air distributors.

Only larger,multicellular creatures require a respiratory system.

What part of the respiratory system serves as resonating chambers for speech?

The lower border of the cavity of the larynx is formed by the:

There are almost 30 million alveoli in the two lungs.

Match each term with its corresponding definition. -system of airways composed of the trachea and two primary bronchi and their many branches

The hilum of each lung is lateral and inferior.

When the intrinsic muscles of the larynx contract,the larynx moves up in the throat.

Because of the rapid blood loss,nosebleeds are frequently a serious problem.

Match each term with its corresponding definition. -external openings into the nasal cavities or the nostrils

The bronchi divide into symmetrical trachea.

Match each term with its corresponding definition. -windpipe; extends from the larynx in the neck to the primary bronchi in the thorax

Match each term with its corresponding definition. -serous membrane in the thoracic cavity

There are seven cartilages of the larynx,three of which are paired.

Most of the structures in the bronchial tree are involved in air distribution rather than gas exchange.

Which of the following is not a subdivision of the thoracic cavity?

How does the structure of the trachea help it accomplish its function?

Which of the following are not part of the external portion of the nose?

The thoracic cavity is lined by visceral pleura.

The palatine tonsils are located at the base of the tongue.
