Respiratory Flashcards
By changing breathing rate, the PCO2 of the blood is changed, leading to a change in blood pH.
This is called?
Physiological buffer
The walls of alveoli are comprised of __________ epithelium.
Simple squamous epithelium
Where does gas exchange between inspired air and blood occur?
Alveoli
The movement of air in and out of the lungs.
What is this called?
VENTilation
Warms, filters, and moistens air as it enters respiratory tract
What organ is this?
Nasal cavity
Reduces weight of skull; voice modulation
What organ is this?
Paranasal Sinuses
Voice production
What organ is this?
Larynx
ex LA LA LA-rynx
Conveys air from nasal cavity to larynx
What organ is this?
Pharynx
Conveys air from larynx to bronchial tree
What organ is this?
Trachea
Structure Entry point for airflow during inspiration
What organ is this?
Nose
Branching structures carrying air to alveoli
What organ is this?
Bronchial Tree
Diaphragm contracts; thoracic cavity expands; intra-alveolar pressure drops; air flows into lungs.
What event this is?
Inspiration
exchange of gas of alveoli & blood = transportation to tissues
INternal respiration
Gas exchange between alveolar AIR and blood (or air & lungs)
EXTERnal respiration
Use of oxygen for metabolic reactions within cells
INTERnal respiration
