| The primary functions of the respiratory system are: | show 🗑
|
||||
| Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. T or F? | show 🗑
|
||||
| The respiratory system is organized into two structural regions: the __ respiratory tract and the __ respiratory tract. | show 🗑
|
||||
| The upper respiratory tract includes: | show 🗑
|
||||
| show | Larynx, trachea, bronchi, bronchioloes, alveolar ducts, and alveoli
🗑
|
||||
| Passageways that serve primarily to transport or conduct air are part of the conducting zone. Transports air. No gas exchange. Structures include: | show 🗑
|
||||
| Structures that participate in gas exchange with the blood are part of the respiratory zone. Structures include: | show 🗑
|
||||
| The __ is the main conducting passageway for inhaled air; it is formed by bone, hyaline cartilage, and dense irregular c.t. covered with skin externally. | show 🗑
|
||||
| show | lateral and alar
🗑
|
||||
| show | nostrils or nares
🗑
|
||||
| The __ __ is an internal space formed by the nose anteriorly and the skull superiorly and posteriorly. It is oblong-shaped, and it extends from the nostrils to paired openings called __ or posterior nasal apertures. This leads into the pharynx. | show 🗑
|
||||
| show | floor, roof
🗑
|
||||
| show | nasal septum; septal nasal
🗑
|
||||
| The __ __ are spaces within the skull bones and named for the skull bones in which they are housed. Ducts connect all of these to nasal cavity. | show 🗑
|
||||
| show | pseudostratified ciliated columnar
🗑
|
||||
| show | frontal, ethmoidal, maxillary, and spehnodial
🗑
|
||||
| The _, commonly called the _, is a funnel-shaped passageway that averages 13cm (5.1 inches) in length. It's located posterior to the nasal cavity, oral cavity, and larynx. Common spaced used by respiratory/digestive systems. Pathway for air and food. | show 🗑
|
||||
| The pharynx is wider superiorly; then narrows. It is partitioned into three regions: | show 🗑
|
||||
| show | nasopharynx, pseudostratified ciliated columnar
🗑
|
||||
| show | oropharynx, nonkeratinized stratified squamous
🗑
|
||||
| show | laryngopharynx, nonkeratinized stratified squamous
🗑
|
||||
| show | nasopharynx, oropharynx and laryngoharynx
🗑
|
||||
| show | 1. cleanse the air, 2. warm the air, 3. humidify the air (moisture)
🗑
|
||||
| The __ also called the __ __, is a somewhat cylindrical airway that averages about 4cm (1.6 inches) in length. It is continuous superiorly with the laryngopharynx and inferiorly with the trachea. | show 🗑
|
||||
| show | passageway for air, prevents ingested materials from entering respiratory tract, produces sound, assists in increasing pressure in abdominal cavity, and participates in both sneeze and cough reflex
🗑
|
||||
| What are the nine cartilages of the larynx? | show 🗑
|
||||
| In the larynx, the __ cartilage is the largest laryngeal cartilage. It's shaped like a shield and forms the lateral and anterior walls of the larynx. | show 🗑
|
||||
| show | laryngeal prominence
🗑
|
||||
| The thyroid cartilage is attached to the lateral surface of the ring-shaped __ cartilage located inferior to the thyroid cartilage. | show 🗑
|
||||
| show | epiglottis
🗑
|
||||
| show | arytenoid, corniculate, and cuneiform cartilages
🗑
|
||||
| All cartilages of the larynx except the epiglottis are composed of __ cartilage. The epiglottis is composed of the more flexible __ cartilage. | show 🗑
|
||||
| The __ __ (true vocal cords) are elastic ligaments covered with a mucous membrane that extend between the thyroid and arytenoid cartilages. These folds surround the rima glottidis and are involved in sound production. | show 🗑
|
||||
| show | intrinsic muscles
🗑
|
||||
| show | sound production
🗑
|
||||
| The __ of a voice is determined by the length and thickness of the vocal cords. Males generally have longer and thicker folds than do females, thus males produce sounds that are in a lower __. | show 🗑
|
||||
| __ refers to the frequency of sound waves. Determined by amount of tension or tautness on the vocal folds as regulated primarily by intrinsic layngeal muscles. Increased tension on folds cause more vibration = higher sound. Reverse for lower sound. | show 🗑
|
||||
| __ depends on the force of air passing across the vocal cords. A lot of air forced through rima glottidisproduces loud sound; little air produces soft sound. | show 🗑
|
||||
| show | trachea, windpipe
🗑
|
||||
| show | tracheal cartilages
🗑
|
||||
| show | pseudostratified ciliated columnar
🗑
