Respiratory Flashcards
is the tubular and cavernous organs that allow atmospheric air to reach the membranes
Respiratory System
is the act of breathing or act of respiring
Respiration
Two phases of respiration
Inspiration
Expiration
is the taking in of air or breathing in
Inspiration
is the breathing out or the expelling air from the lungs
Expiration
At ____ the intercostal contract to elevate the ribs and at the same time
Inspiration
contracts and is displaced downwards thus, increase in size of the chest cavity
Diaphragm
air then passes out from the lungs to aqualize the pressure is
Expiration
Respiration occurs about ____
18 times per minute
what are the parts of the respiration system
Respiratory passages
Lungs
Respiratory Passages
- Nasal cavities or Nasal fossae
- Pharynx / Throat
2.1 Nasopharynx
2.2 Oropharynx
2.3 Laryngeal Part - Larynx / Voice box
- Trachea / Windpipe
- Bronchi / Bronchial tubes
- Bronchioles ā- Little Bronchi
Lungs
A. Right Lung
B. Left Lung
in right lung how many lobes
3 Lobes
in left lung hoe many lobes
2 lobes
is a hollow tube about 4.5 inches in length extending from the larynx to the bronchi below
Trachea / Windpipe
it commences opposite the sixth cervical vertebra (C6) and extends down to the fourth dorsal body (T4)
Trachea / Windpipe
lies in the neck below the adams apple and the rest lies in the superior mediastinum and in front of the esophagus
Upper part of Trachea
is lined by epithelium and the walls are straightened by the incomplete rings of cartilage which are open behind like a letter āCā
Trachea
fill in the gap behind
Muscle Fibers
the trachea divides into two tubes called
Bronchi (sing. bronchus)
is divided into 3 divisions one for each lobe of the (R) lung
Right Main Bronchus
is also divided into 2 lobar bronchi, one for each lobe of the (L) lung
Left Main Bronchus
is the panty-like structure on the bifurcation of the two bronchi
Carina / Keel
are tye final minute tubes and are continuous with the air spaces of the lungs
Bronchioles / Little Bronchi
are the organs of respiration that occupy the right and left chest cavities
Lungs
the partition between the two halves of the chest
Mediastinum (Middle Septum)
it extends from the the base of the neck to the diaphragm
Mediastinum (Middle Septum)
each lung is con-shaped with ____ reaching about one inch above the clavicle
pointed end or apex
the pointed end or alex in the lungs is also called
Cupula
it rest upon the convex surface of the diaphragm
lower end or base
are spongy, crepitant, float on water and have elastic tissue in their walls
Lungs
frequently blue-gray in color because of inhaled dusts
Lungs
natural division that separate the lobes of the lungs
Fissure or Grooves
the right lung is divided into (3) lobes or division
- Upper / Superior Lobe
- Middle Lobe
- Lower / Inferior Lobe
the left lung us divided into (2) lobes or division
- Upper / Superior Lobe
- Lower / Inferior Lobe
are the structural units or divisions of the lobes of the lungs, one for each segmental bronchus
Bronchopulmonary Segments
in right lung, 3 lobes, there are 10 bronchopulmonary segments of the lungs what are they
Upper Lobe:
Apical
Posterior
Anterior
Middle Lobe:
Lateral Middle Lobe
Medial Middle Lobe
Lower Lobe:
Superior Basal
Posterior Basal
Medial Basal
Anterior Basal
Lateral Basal
in left lung, 2 lobes, there are 8 bronchopulmonary segments of the lungs what are they
Upper Lobe:
Apical Posterior
Anterior
Middle Lobe:
Superior Lingual
Inferior Lingual
Lower Lobe:
Superior Basal
Posterior Basal
Anterior Medial Basal
Lateral Basal
are small units of each bronchopulmonary segment containing many minute air sacs
Lobules (Little Lobes)
is the active tissue of the lungs
Parenchyma
is a depression on the medial surface of each lung where vessel and bronchi enters into the lungs
Hilum / Hilus
is its attachment to the mediastinum and is composed of all the structures
Lung Root
is the lining membrane of the chest cavity and the covering membrane of each lung
Pleura
What are the covering membrane of Pleura
A. Visceral Pleura
B. Parietal Pleura
is the space between the lungs and the chest wall between the visceral and parietal pleura
Pleural Cavity
is the triangular space in the lower chest between the chest wall and the adjacent rounded margin of the diagphram
Costophrenic Sinus or Sulcus
