EZ-Anat Ch. 17

Barron's E-Z Anatomy and Physiology Chapter 17

Oxygen and carbon dioxide are transported between the cells of the body and the respiratory system by the: circulatory system
The smallest branches of the respiratory system tubes terminate in clusters of microscopic air sacs called: alveoli
Blood enters the lung from the heart through a major artery known as the: pulmonary artery
The mouth and nasal cavities meet in a region called the: pharynx
The nasal cavities open to the external environment at the nostrils, also called the: external nares
Many bones of the skull contain openings from the nasal cavities referred to as: sinuses
At the roof of the nasal cavities the sense of smell is associated with an area called the: olfactory region
Three functions of the nose include moistening the air, filtering the air, and: warming the air
Another name for the pharynx is the: throat
The lateral walls of the nasopharynx contain openings of tubes from the middle ear known as: auditory tubes
The largest cartilage of the larynx, also known as the Adam's apple is the: thyroid cartilage
The cartilage of the larynx that resembles a signet ring and connects the trachea and larynx is the: cricoid cartilage
The opening to the larynx is referred to as the: glottis
Vibrations of the vocal chords are due to air exhaled from the: lungs
Because men have longer vocal chords, their voices have lower: pitch
The trachea is supported by a series of C-shaped rings of: cartilage
The two primary tubes that branch from the trachea are the: bronchi
There is no cartilage in the tubes when the bronchi become: bronchioles
Bronchiole walls are composed mostly of muscle referred to as: smooth muscle
The common name for inflammation of the bronchial tree is: bronchitis
The lungs occupy most of the space of the: thoracic cavity
The left lung is subdivided into two lobes, while the right lung is subdivided into: three lobes
The two-layer membrane surrounding each lung is the: pleura
The underlying principle of breathing is that air flows from the region of high pressure to a region of: low pressure
Pressure changes occurring in the lungs can be traced to the activity of skeletal muscles known as: respiratory muscles
During inspiration, contractions cause the downward movement of a dome-shaped muscle known as the: diaphragm
The relaxation of respiratory muscles compresses the thorax and increase the air pressure in the: lungs
While inspiration is an active process, the process of expiration is a(n): passive process
The volume of air that can be forced out of the lungs after a forced inspiration is the: vital capacity
Breathing is controlled by an area of the brain called the respiratory center, which includes part of the medulla oblongata and the: pons
