Respiratory System Ch.7 Flashcards
functions of respiratory system
responsible for exchange of 02 and CO2, helps regulate the pH of the blood.
Pharynx consists of how many and what chambers?
nasopharynx, oropharynx, and laryngopharynx
Larynx
Voice box
Upper respiratory tract
Nasal cavity, pharynx, larynx, trachea
Lower respiratory tract
bronchi, lungs, bronchioles, and aveoli

Space between the right and left lungs (contains heart, aorta, esophagus, and bronchi)
Respiration process
pulmonary ventilation, external respiration, transport or respiratory gases, internal respiration
Pulmonary ventilation
breathing. moves air into and out of the lungs in response to changes in the blood O2/CO2 levels.
External respiration
the exchange of O2 and CO2, between the alveoli and the pulmonary capillaries.
Transport of respiratory gases
occurs when blood, aided by the cardiovascular system, transports CO2 to the lungs and O2 to the body cells
Internal respiration
The exchange of O2 and CO2 between body cells and the blood in systemic capillaries
