EZ-Anat Ch. 17
Barron's E-Z Anatomy and Physiology Chapter 17
| Question | Answer |
|---|---|
| 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 |
