*KNOW epithelial linings
AND support tissues of respiratory system structures BIOLOGY 2213: James Adams
Lymphatic System I. Lymphatic Vessels: Capillaries, including lacteals; main trunks/ducts (lumbar,
intenstinal,
bronchomediastinal, subclavian,
jugular trunks; right lymphatic, thoracic ducts) Cisterna chyli
II. Lymphoid Organs: Follicles/germinating centers; cortex/medulla
with medullary cords
Diffuse Lymphatic Tissue
Lymph nodes (with afferent/efferent vessels
exiting hilus/hilum)
-- inguinal, axillary, and
cervical groups
Spleen (with red/white pulp)
Thymus
Tonsils (with crypts): pharyngeal (adenoids) and tubal, palatine, and lingual in/on
nasopharynx, oropharynx and tongue, respectively
Peyer=s Patches (in ileum) and
Appendix
Respiratory System*
CONDUCTING ZONE -- wall: mucosa (know epithelial
linings) and submucosa
I. Nose/Nasal Cavities: (bounded by hard/soft palate
[uvula] on floor)
External/Internal nares
Nasal Conchae/Meati
Paranasal Sinuses -- frontal, maxillary, sphenoid
II. Pharynx: see Tonsils, under lymphatic system (above)
Nasopharynx, with tubal/pharyngeal tonsils
Oropharynx, with palatine tonsils
Laryngopharynx
III. Larynx (Voice Box)
Epiglottis/glottis
Vocal cords/folds
Cartilages: know thyroid (laryngeal prominence), cricoid, and arytenoid
Cricothyroid ligament
Hyoid bone
IV. Trachea (with hyaline cartilage C-rings and trachealis muscles)
V. Bronchial Tree --
Carina (hyaline cartilage
wedge) at base of trachea; begins separation of . . .
Primary bronchi (R & L), secondary (lobar)
bronchi
Bronchioles (including terminal)
RESPIRATORY ZONE
V. (continued). Respiratory bronchioles
VI. Alveoli Respiratory membrane
