Anatomy and Physiology Flashcards
Three processes of Respiration
Ventilation, Diffusion and Perfusion
Process of gaseous exchange between individual and environment
RESPIRATION
Movement of gases in and out of the lungs
Ventilation
The Upper Respiratory Tract consists of:
Nose, Pharynx, Larynx and Trachea
The Lower Respiratory Tract consists of:
Bronchi and Bronchioles
Alveolar ducts and Alveoli
Pleural cavities
Larynx consists 5 cartilages and these are
Thyroid Cricoid Arytnoid Corninuate Cuneiform
This organ performs phonation
Larynx
What is the diameter and length of trachea?
Diameter 2.5 cm
Length 10-14 cm
Division part of Left bronchus and Right bronchus
CARINA
Right Lung and Left lung consists of how many lobes?
Right Lung - 3 lobes
Left Lung - 2 lobes
This cell responsible for surfanctant production
Septial Cells
This engulfs the debris
Alveolar macrophages
What is Mucociliary Transport System?
Defense mechanism for foreign bodies (macro and micro)
This cavity bounded by the ribcage and the muscular diaphragm
Thoracic cavity
Exchange of gases between the alveolar-pulmonary capillaries
External respiration
