HCB 102 Respiratory Test Questions and
Correct Answers
No breathing ✅Apnea
A bluish or purplish color of the skin due to insufficient oxygen levels in the blood.
✅Cyanosis
A process by which molecules move from an area of high concentration to an area of
low concentration. ✅Diffusion
Difficult and labored breathing, shortness of breath. ✅Dyspnea
A deficiency of oxygen reaching the tissues of the body. ✅Hypoxia
Situated or extending between the ribs. ✅Intercostal
Increased work of breathing; sensation of shortness of breath. ✅Respiratory distress
Reduction of breathing to the point where oxygen intake is not sufficient enough to
support life. ✅Respiratory failure
Pulling in the skin and soft tissue between the ribs when breathing. ✅Retractions
The oropharynx and nasopharynx are both include in the ✅pharynx
Closes over the glottis to prevent food and foreign objects from entering the trachea.
✅Epiglottis
Contains the vocal cords; connects the pharynx with the trachea (contains thyroid
cartilage, known as the adams apple). ✅Larynx
Forms the lower portion of the larynx. ✅Cricoid cartilage
The tube that carries inhaled air from the larynx toward the lungs. ✅Trachea
Splits into two branches (one going to each lung). ✅Bronchi
Consists of the trachea, primary and secondary bronchi, tertiary bronchi, bronchioles
and terminal bronchioles. ✅Bronchial tree
Air passages end at the ✅Alveoli
, Small sacs within the lungs where gas exchange takes place with the bloodstream,
across the alveolar-capillary membrane. ✅Alveoli
Divides the chest cavity from the abdominal cavity (helps a person inhale and exhale).
✅Diaphragm
Active process in which the muscles of the rib cage and the diaphragm contract.
✅Inhalation
The expanding size of the chest creates a negative pressure inside the chest causing
the cavity to ✅pull air into the lungs
Passive process during which the intercostal muscles and the diaphragm relax.
✅Exhalation
The chest decreases in size and positive pressure builds inside the chest cavity which
causes air to be ✅pushed out of the lungs
Classified as adequate (sustains life) or inadequate (does not sustain life). ✅Breathing
_______________ detect increasing levels of carbon dioxide as well as low levels of
oxygen and stimulates the respiratory system to breath more rapidly.
✅Chemoreceptors
Process of inhaling and exhaling. ✅Ventilation
Oxygen is transferred from the air inside the lunges to the alveoli to the bloodstream via
the ✅Pulmonary capillaries
Carbon dioxide is moved from the bloodstream via the pulmonary capillaries into the
✅Alveoli
Refers to the exchange of gases between the alveoli and the blood (external
respiration) and between the blood and cells (internal respiration). ✅Respiration
Inhaled air fills the ✅Alveoli
____________ _____________ bring circulated blood to the outside of these tiny sacs
(alveoli). ✅Pulmonary capillaries
The diffusion of oxygen and carbon dioxide that takes place between the alveoli and
circulating blood is called ✅Pulmonary respiration
