Respiratory system Flashcards
Osmotic and chemical process
Respiration
3 separate but related functions
- Ventilation
- Gas Exchange
- Oxygen utilization
Ventilation and gas exchange in the lungs.
External respiration
Gas exchange between the blood and other tissues.
Internal respiration
Structures of the Respiratory System
- nasal cavity
- pharynx
- larynx
- trachea
- bronchi
- bronchioles
- pulmonary alveoli
Nasal cavity, pharynx and larynx
Upper respiratory
Trachea and lungs
Lower respiratory
Nsal cavity, pharynx, larynx, trachea, bronchi, bronchioles
Conducting division
Respiratory bronchioles, alveolar ducts and sacs and pulmonary alveoli
Respiratory division
Pumping Mechanism of the Respiratory System
Thoracic cage
Diaphragm
Types of Breathing
Costal (thoracic)
Abdominal (diaphragmatic)
Occurring when more air is needed than movement of the diaphragm produces.
Costal (thoracic)
Occurring during ordinary quiet breathing.
Abdominal (diaphragmatic)
Normal quiet respiration
Eupnea
Difficult breathing
Dyspnea
Absence or cessation of respiration
Apnea
Increased depth or rate of breathing or both
Hypernia
Rapid, shallow breathing
Polypnea
- embodied within the skeleton of the face
- extends from about the transverse level of the eyes to the rostral extremity of the head
- comprises the parts of the face rostral to the eyes and dorsal to the mouth
Nose
External openings of the respiratory tract
External nares (nostrils)
Lacks a planum, its nose being instead covered with fine hair.
