Respiration Flashcards
Two process in respiration
Internal respiration and external respiration
Respiratory system include
Lungs
airways leading to lungs
and structures in the thorax which is responsible for moving air into and out of the lungs
In airway branching what are the two zones
Conducting zone and respiratory zone
What type of discharge for contraction of bronchi and bronchioles
Cholinergic discharge
Nor Adri genic discharge for
Relaxation from beta-2 receptor
Number of alveoli
300 million
Length of alveoli
Zero. 5 µm
Alveoli’s are made up of what type of tissue
Elastic tissue
Alveoli are surrounded by
Pulmonary capillaries
Which type of epithelial cells in the alveoli produces surfactant
Type two
Three pressure consideration
Atmospheric pressure
Intra-alveolar pressure
Intrapleural pressure
Atmospheric pressure also known as
Barometric pressure
Range of atmospheric pressure at sea level
760 mm Hg
Intrapulmonary pressure also known as
Intraalveolar pressure
Intrathoracic pressure also known as
Intrapleural pressure
