What is the name of the passageway shared by the digestive and respiratory system for air and food?
The pharynx is also known as the throat. The nasal cavity and the mouth share this passageway. Air moves down the larynx and food travles into the esophogus
What happens to your diaphragm during inhalation?
B) moves upward
Inhalation is an active process. The diaphragm contracts in a downward motion drawing air into the lungs
What leaf shaped structure closes during swallowing to prevent foods and foreign objects from entering the trachea?
D) cricoid cartilage
The epiglottis is a small leaf shaped cartilaginous tissue that prevents food and water from entering the trachea. When you swallow, it falls down and covers the trachea opening. When you breathe, it lifts upward and allows air to pass.
Where is Sellick's maneuver applied?
B) cricoid cartilage
C) thyroid gland
Sellick's maneuver is also called cricoid pressure. It inhibits gas entering the stomach during assisted ventilations.
What ring shaped structure forms the lower portion of the larynx?
C) cricoid cartilage
The inferior portion of the larynx is a cartilaginous ring. It is located directly inferior of the Thyroid cartilage.
What is the name of the muscular structure that divides the chest cavity from the abdominal cavity?
A) smooth muscle
The diaphragm is a large muscle used for breathing. On inhalation it contracts downward, allowing air to be drawn in the mouth or nose and proceed down into the lungs. Upon exhalation the diaphragm relaxes, allowing air to passively leave the airway
What part of the respiratory system contains the vocal cords?
This structure is directly above the trachea. The vocal cords are located here. It is also known as the voice box
What area is directly posterior to the mouth?
The oropharynx is the central location of the pharynx. It is located from the opening of the mouth until the epiglottis
What is the name of the cartilaginous ridge in the trachea at which the right and left lungs split?
B) cricoid cartilage
D) xiphoid process
The trachea splits into 2 main stems, the left and right, at the carina. Each direction leads into a lung. The carina is located beneath the sternum
How many lobes are in the lungs?
The lungs have a total of 5 lobes, 3 on the right and 2 on the left
What is the name of the hollow, semi flexible tube that carries inhaled air from the larynx to the lungs?
The trachea is a tube like structure that allows air passage from the upper airway into the lungs
What is directly posterior to the nose?
The nasopharynx connects the opening of the nostrils to the soft palate, which is located at the back of the mouth. This passage is designed to warm up inhaled air and filter out fine particulate
What is the common location for an airway obstruction?
This passageway is shared by air and food, so it is a common site for a partial or complete obstruction, which could be food or a flaccid tongue
What is the normal respiratory rate for an adult?
The normal respiratory rate for an adult is 12-20. This number allows for adequate oxygen and carbon dioxide exchange
What are the small sacs in the lungs that are responsible for gas exchange?
Alveoli are the smallest portions of the lung tissue. This is where gas exchange takes place. Capillaries are located on the outside of the alveoli and they share a wall (membrane) with the alveoli sacs. The small sacs are kept open by a soapy substance known as surfactant. Without surfactant the alveoli collapse and gas exchange is inhibited. With congestive heart failure (CHF) blood replaces surfactant and the alveoli collapse, and when they collapse, this decreases the amount of surface area for gas exchange
