1 Respiratory Models & Histology Lab Book Page 339

2 Fig. not in your lab book

3 The Upper Respiratory Structures Nasal Cavity –Contains the superior, middle and inferior nasal conchae Pharynx –Divided into three sections the nasopharynx, oropharynx and laryngopharynx

4 Lab Book page 340

5 Sagittal Head Superior Nasal Conchae Middle Nasal Conchae Inferior Nasal Conchae External nares

6 Sagittal Head Frontal Sinus Sphenoid (Sphenoidal) Sinus Nasopharynx Oropharynx Laryngopharynx

7 Sagittal Head Larynx – Epiglottis Larynx – Thyroid Cartilage Esophagus

8 The Lower Respiratory Structures Larynx –Made of cartilage and ligaments – 3 Major cartilages of the larynx: Thyroid cartilage Cricoid cartilage Epiglottis –Contains vocal cords, which surround an opening called the glottis

9 Lab Book page 342

10 Larynx Anterior View Epiglottis Thyroid Cartilage Laryngeal Prominence Cricoid Cartilage Tracheal Cartilage Hyoid Bone

11 Larynx Superior View Epiglottis Glottis (hole) Vocal Cords Arytenoid Cartilage

12 Trachea Windpipe – brings air to/from lungs Contains tracheal cartilages which protect the airway and prevent collapse Fig. not in you lab book

13 Bronchial Tree Fig. not in you lab book

14 Thoracic Model – Internal View Right Brachiocephalic vein Left Brachiocephalic vein Superior Vena Cava Esophagus Aortic Arch Pulmonary Arteries Pulmonary Veins

15 Thoracic Model – Internal View Trachea Primary bronchus Secondary bronchus Tertiary Bronchus

16 Thoracic Model – External View Right Lung Superior Lobe Right Lung Middle Lobe Right Lung Inferior Lobe Diaphragm Left Lung Superior Lobe Cardiac notch of left lung Left Lung Inferior Lobe

17 2 Respiratory Slides 1. Slide of the TRACHEA 2. Slide of a BRONCHIOLE

18 SLIDE OF TRACHEA – lab book pg. 345 Fig. 6 LUMEN of Trachea Pseudostratified Ciliated Columnar Epithelium Hyaline Cartilage Goblet Cells

19 Close-up of Trachea showing a Goblet Cell Goblet Cell

20 Bronchiole & Alveoli Fig. not in you lab book

21 Also known as a septal cell: produces SURFACTANT which reduces the surface tension in the alveoli Fig. not in you lab book

22 Slide of a Bronchiole Bronchiole (notice it is filled with air so it is empty inside) Alveoli or Alveolar Sacs Simple Squamous Epithelia Blood Vessel (notice it is filled with RBC’s) Lab Book page 346 Fig. 7 (b) Alveoli or Alveolar Sacs

23 Practice Slides!!!
